Datasheet
XT Family of Ultra-low Phase Noise XT Quartz-based PLL Oscillators Datasheet 

## Description 

The XT devices are ultra-low phase noise quartz-based PLL oscillators supporting a large range of frequencies and output interface types. 

The XT devices can be programmed to generate an output frequency from 15MHz to 2100MHz with a resolution as low as 1Hz accuracy. The configurability of this family of devices provides fast delivery times for both sample and large production orders. 

Parts may be factory programmed for fixed frequency applications, or may be field configured using the I2C interface. 

## Features 

- Output types: LVDS, LVPECL, CML 

   - Frequency range: 15MHz to 2100MHz 

- Output type: HCSL 

   - Frequency range: 15MHz to 725MHz 

- Supply voltage options: 1.8V, 2.5V, 3.3V 

- Phase jitter (12kHz to 20MHz): 135 fs typical 

- Package options: 

   - 3.2 × 2.5 × 0.85 mm 

- Operating temperature and stability: 

   - -40°C to +85°C, ±3ppm 

- Frequency stability for life: 

   - -40°C to +85°C, ±13ppm

## Absolute Maximum Ratings 

Stresses above the ratings listed below can cause permanent damage to the device. These ratings, which are standard values for Renesas commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure t ~~o~~ absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range. Thermal characteristics, in actual applications, should be assessed case by case to guarantee junction temperature does not exceed 125°C.

## LVDS Output Termination 

For a general LVDS interface, the recommended value for the termination impedance (ZT) is between 90Ω and 132Ω. The actual value should be selected to match the differential impedance (Z0) of your transmission line. A typical point-to-point LVDS design uses a 100Ω parallel resistor at the receiver and a 100Ω differential transmission-line environment. In ~~o~~ rder to avoid any transmission-line reflection issues, the components should be surface mounted and must be placed as close to the receiver as possible. Renesas offers a full line of LVDS compliant devices with two types of output structures: current source and voltage source. 

The standard termination schematic as shown in Figure 7 can be used with either type of output structure. Figure 8, which can also be used with both output types, is an optional termination with center tap capacitance to help filter common mode noise. The capacitor value should be approximately 50pF. If using a non-standard termination, it is recommended to contact Renesas and confirm if the output structure is current source or voltage source type. In addition, since these outputs are LVDS compatible, the input receiver’s amplitude and common-mode input range should be verified for compatibility with the output.

## HCSL Output Termination 

Figure 9 is the recommended source termination for applications where the driver and receiver will be on a separate PCBs. This termination is the standard for PCI Express™ and HCSL output types. All traces should be 50Ω impedance single-ended or 100Ω differential. Figure 10 is the recommended termination for applications where a point-to- ~~po~~ int connection can be used. A point-to-point connection contains both the driver and the receiver on the same PCB. With a matched termination at the receiver, transmission-line reflections will be minimized. In addition, a series resistor (Rs) at the driver offers flexibility and can help dampen unwanted reflections. The optional resistor can range from 0Ω to 33Ω. All traces should be 50 Ω impedance single-ended or 100Ω differential.

## Marking Diagram 

## Figure 12.  Marking Configuration for the 3.2 × 2.5 mm (LNG8) Package (example based on XTL312625.000000I) 

▪ Line 1 denotes the truncated part number as follows: 

- Dxxxxxx • “D” = a combination of the 3rd digit (output type, e.g. “ **L** ”) and the 5th digit (voltage supply, e.g. “ **3** ”), in accordance with the mapping key as follows: 

- YWW**$ 

      - C1 = A, C2 = B, C3 = C, **L1 = D** , L2 = E, L3 = F, N1 = G, N2 = H, N3 = J, P1 = K, P2 = L, P3 = M 

   - “xxxxxx” = the first three digits to the left of the decimal point and the last three digits to the left of the decimal point as shown in the above example. This number will vary depending upon the frequency value selected in the orderable part number. (e.g. 625000). 

## ▪ Line 2 indicates the following: 

- “YWW” denotes the last digit of the year and week when the part was assembled. 

- “**” denotes the sequential lot number. 

- “$” denotes the mark location.
