## **DescripTion**
The LTC[®] 6930 series is a family of very low power precision silicon oscillators with a frequency error less than 0.09%. For each oscillator, the user can select one of 8 frequencies between 32.768kHz and 8.192MHz. Based on a fixed master oscillator frequency, internal frequency dividers between 1 and 128 provide the 8 different frequencies. The LTC6930 requires no external components other than power supply bypass capacitors. Requiring only a single 1.7V to 5.5V supply enables operation from a single Li-Ion cell or 2 AA alkaline cells.
The LTC6930 features a proprietary control architecture that allows for ultralow power operation while maintaining industry leading accuracy and jitter specifications. The exceptionally fast start-up time, combined with the low power consumption, is ideal for battery operated applications with frequent power-up cycles.
Any frequency from 32.768kHz to 8.192MHz can be provided by the factory. Minimum order sizes apply for custom frequencies. Please consult LTC Marketing for details.

**Note 1:** Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.
**Note 2:** LTC6930C is guaranteed functional over the operating range of –40°C to 85°C.
**Note 3:** The LTC6930C is guaranteed to meet specified performance from 0°C to 70°C. The LTC6930C is designed, characterized and expected to meet specified performance from –40°C to 85°C but is not tested or QA sampled at these temperatures. The LTC6930I is guaranteed to meet specified performance from –40°C to 85°C. The LTC6930H is guaranteed to meet specified performance from –40°C to 125°C. The LTC6930MP is guaranteed to meet specified performance from –55°C to 125°C.
**Note 4:** Frequency accuracy and frequency drift are defined as deviation from the nominal frequency or the nominal frequency divided by the integer set through the DIV pins for each part. The nominal frequency for
the LTC6930 family of parts are defined as follows:
LTC6930-4.19 fNOM = 4.194304MHz LTC6930-5.00 fNOM = 5.000000MHz LTC6930-7.37 fNOM = 7.372800MHz LTC6930-8.00 fNOM = 8.000000MHz LTC6930-8.19 fNOM = 8.192000MHz
**Note 5:** Long-term drift of silicon oscillators is primarily due to the movement of ions and impurities within the silicon and is tested at 30°C under otherwise nominal operating conditions. Long-term drift is specified as ppm/√kHr due to the typically non-linear nature of the drift. To calculate drift for a set time period, translate that time into thousands of hours, take the square root and multiply by the typical drift number. For instance, a year is 8.77kHr and would yield a drift of 89ppm at 30ppm/√kHr. Drift without power applied to the device may be approximated as 1/10th of the drift with power, or 3ppm/√kHr for a 30ppm/√kHr device.

## **pin FuncTions**
**V[+] (Pins 1, 8):** Positive Supply Pins. Each supply pin should be bypassed directly to the neighboring GND pin with a 0.1µF ceramic capacitor, and must be externally connected to the other V[+] pin (see recommended layout).
**GND (Pins 2, 6):** Ground Pins. Each should be connected to a low inductance ground plane and must be connected to the other GND pin and on the DFN package, Pin 9.
**DIVA, DIVB, DIVC (Pins 3, 4, 5):** Output Prescaler. Selects divide ratio of master oscillator frequency used to generate the output. See frequency setting Table 1 for function. These are standard CMOS logic inputs with a typical threshold of 1.25V
**OUT (Pin 7):** Oscillator Output. Drives up to 50pF capacitive or 1k resistive load (Refer to Supply Current vs Load Capacitance in Typical Performance Characteristics section). Typical series resistance is less than 80Ω at 1.7V and less than 40Ω at 3V supply. The output trace should be isolated as much as possible from Pin 1 and Pin 2. The OUT pin is held low during start-up, and remains free from glitches and runt pulses during DIV pin switching.
**Exposed Pad (Pin 9, DFN Only):** The Exposed Pad must be soldered to a PCB plane connected to GND.
## **applicaTions inForMaTion**
## **Theory of Operation**
The LTC6930 is an entirely self contained all silicon oscillator which consists of a master oscillator, a control loop and an output frequency divider. The master oscillator operates between 4.2MHz and 8.2MHz and is factory programmed. The master oscillator frequency is accurately maintained over temperature and environmental extremes by a proprietary switched capacitor feedback loop.
Each LTC6930 oscillator has an output frequency divider which is controlled via the DIVA, DIVB and DIVC inputs. The divider divides the master frequency by 2[N] , where N is an integer from 0 to 7 (divider ranges from 1 to 128). See Table 1 for the full range of frequencies covered by the LTC6930 family.
The presence of two sets of supply pins and careful internal layout reduce interference between the oscillator output and the control loop. This allows the LTC6930 to provide a clean output frequency with very little deterministic jitter, even in cases of heavy output loading and noisy operating environments.
The supply voltage of the LTC6930 is internally regulated to maintain a very low frequency drift over supply.
## **Output Driver and Loading**
The output of the LTC6930 is a low series resistance 40Ω CMOS driver with controlled rise/fall times to limit RF interference and power supply spikes generated by the output while preserving the ability to drive low impedance loads. Especially at high frequencies, the capacitive loading of the output of the LTC6930 may cause the majority of the power supply dissipation of the part.
The LTC6930 supply current is specified at an output load of 5pF, which is equivalent to two standard HC logic inputs. The portion of the power supply current needed to drive a capacitive load may be calculated as:
## ISUPPLY = CLOAD • VSWING • fOSC
where CLOAD is the 5pF load capacitance, VSWING is the voltage swing, in this case up to 5.5V, and fOSC is the frequency of the oscillator output. Driving a 5.5V swing into a 5pF load at 8MHz takes an average of 220µA. To calculate the portion of the supply current needed for a 50pF load, simply substitute 50pF for CLOAD in the same equation:
50pF • 5.5V • 8MHz = 2.2mA
The majority of this power is expended during the rise and fall time of the output signal, not while it is in a steady

state. The 2ns rise and fall times of the LTC6930 mean that the instantaneous power supply current required during the rise and fall portions of the waveform is much greater than the average.
The instantaneous power supply current may be calculated by a similar formula:
**==> picture [133 x 30] intentionally omitted <==**
where trf is the rise/fall time of the signal. In this case, 14mA spikes are generated by driving 5.5V into a 5pF load.
Power is supplied to the output driver of the LTC6930 from the V[+] and GND pins on each side of the output pin (Pins 6 and 8). Allowances must be made in the design to provide for output load related supply current spikes, especially in high accuracy applications. A 0.1µF ceramic capacitor connected between V[+] and GND (Pins 6 and 8) as close as possible to the device will decouple the rest of the circuit from spikes caused by powering a capacitive output load of up to 50pF. See Figure 1.

## **Switching the DIV Pins**
The LTC6930 is designed to quickly and cleanly respond to the digital inputs. The output will respond to the DIV pins within a single clock cycle without introducing any sliver or runt pulses.
## **Start-Up Time**
The start-up time of the LTC6930 is typically 50µs from the time that valid power is applied to the first output pulse. The output is held low for the first 50µs to prevent any glitches, runt pulses, or invalid frequency output during start-up.
## **Long-Term Drift**
Long-term stability of silicon oscillators is specified in ppm/√kHr, which is typical of other silicon devices such as operational amplifiers and voltage references. Because drift in silicon-based oscillators is generated primarily by movement of ions in the silicon, most of the drift is accomplished early in the life of the device and the drift can be expected to level off in the long term. The ppm/√kHr unit models this time variant decay. Crystal oscillators are often specified with drift measured in ppm/year because their drift mechanism is different. A comparison of various drift rates over a five year time period is shown in Figure 2.
When calculating the amount of drift to be expected, it is important to consider the entire time in the calculation, because the relationship to time is not linear. The drift for

5 years is not 5 times the drift for one year. A sample calculation for drift over 5 years at 30ppm/√kHr is as follows:
5 years • 365.25 days/year • 24 hours/day = 43,830 hours = 43.830kHr
- √43.830kHr = 6.62√kHr
6.62√kHr • 30ppm/√kHr = 0.0198% over 5 years.
Drift calculations assume that the part is in continuous operation during the entire time period of the calculation. The movement of ions which results in drift is usually aided by electric fields in the operating parts, and the typical drift spec applies while the part is powered up. Conservative calculations would use a tenth of the drift specification for time when power is not applied to the part.
## **Setting the Frequency**
The output frequency of the LTC6930 is chosen from the values in Table 1 and set using the DIV pins, as noted in the table. Master oscillator frequency is preset in the factory, and the DIV pins select an internal binary divider of up to 128.
For example, if the desired oscillator output frequency is 2.5MHz, finding 2.5MHz in Table 1 shows that the LTC6930-5.00 should be ordered, having a master oscillator frequency of 5MHz, and a DIV value of [001] should be used. This would equate to grounding DIVC and DIVB, while connecting DIVA to the positive supply. Frequencies other than those shown in Table 1 may be requested.
