In addition to standard differential signal types, a unique FlexSwing™ output-driver performs like LVPECL and provides independent control of voltage swing and DC offset to simplify interfacing with chipsets having nonstandard input voltage requirements and eliminate all external source-bias resistors. The device also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for an external dedicated LDO. The SiT9375 can be factory programmed for specific combinations of frequency, stability, output signaling, voltage, and output enable functionality. Programmability enables designers to optimize clock configurations while eliminating long lead times and customization costs associated with quartz devices where each combination is custom built. The wide frequency range and programmability makes this device ideal for communications, enterprise, and industrial applications that require a variety of frequencies and operate in noisy environments. Refer to Manufacturing Notes for proper reflow profile, tape and reel dimension, and other manufacturing related information. ## **Block Diagram** ## **Features** - Standard frequencies from 25 MHz to 644.53125 MHz - 150 fs RMS typical phase jitter, 12 kHz to 20 MHz - 9 fs/mV typical PSNR - LVPECL, LVDS, HCSL, Low-power HCSL, and FlexSwing signaling options - ±20, ±25, ±30, and ±50 ppm frequency stabilities - Wide temperature range (-40°C to 105°C) - Factory programmable options for low lead time - 1.8 V, 2.5 V, 3.3 V, and wide continuous power supply voltage range options - 2 x 1.6, 2.5 x 2, 3.2 x 2.5 mm x mm package (Contact SiTime for 7 x 5, and 5 x 3.2 mm x mm packages) ## **Applications** - 100G/200G/400G/800G network equipment - Optical modules - Coherent optics - Network switches, routers - Industrial networking equipment - Server and storage systems - Test and measurement - Broadcast video ## **Package Pinout** **==> picture [107 x 67] intentionally omitted <==** **----- Start of picture text -----**

The conduction thermal resistances θJB and θJC are obtained with the assumption that all heat flows from the junction to a heat sink through either the solder pads (θJB) or the top of the package (θJC,Top). These may be used in a two-resistor compact model. The values of θJA and ΨJT are strongly application dependent, and we report values based on the JEDEC thermal environment. θJA is the thermal resistance to ambient on a JEDEC PCB - it is a highly conservative estimate, since the JEDEC board does not have vias to PCB planes in the vicinity of the package. ΨJT can be used to estimate the junction temperature from measurements of the temperature at the top of the package, if the thermal environment is similar to the JEDEC environment. ## **Table 14. Maximum Operating Junction Temperature[[5]]** |**Max Operating Temperature (ambient)**|**Maximum Operating Junction Temperature**| |---|---| |70°C|85°C| |85°C|100°C| |95°C|110°C| |105°C|120°C| ## **Notes:** 5.

OE pin includes a 120 kΩ internal pull-up resistor to VDD when active high, and a 120 kΩ internal pull-down resistor to GND when active low. In noisy environments, the OE pin is recommended to include an external 1 kΩ resistor (Use 1 kΩ pull-up if active high OE; use 1 kΩ pull-down if active low OE) when the pin is not externally driven. 8. Differential Logic high means OUTP=VOH, OUTN=VOL. 9. Can be left open. SiTime recommends grounding it for better thermal performance. 10. A capacitor of value 0.1 µF or higher between VDD and GND pins is required. Proprietary & Confidential of SiTime Page 14 of 29 Rev 0.91 PRELIMINARY **SiT9375** Low Jitter Differential XO for Standard Frequencies ## **FlexSwing Configurations** A FlexSwing output-driver performs like LVPECL and additionally provides independent control of voltage swing and DC offset voltage levels. This simplifies interfacing with chipsets having non-standard input voltage requirements and can eliminate all external source-bias resistors. FlexSwing supports power supply voltages from 1.71 V to 3.63 V, and the programmable VOH and VOL levels may be referenced to the voltage on either VDD or GND pins. **Table 17.

The above table identifies supported combinations of nominal VOH (i.e. VHn) and nominal VOL (i.e. VLn) in colored boxes. The two-character code in each box corresponds to the VHn and VLn codes specified in the 2[nd] column and 2[nd] row in the table, respectively. The number in each box indicates the nominal differential swing (i.e. VHn – VLn). For example, order code “FS selects VHn code “F (i.e. Vdd-1.144 V) and VLn code “S (i.e. Vdd-1.530 V) corresponding to a V_Swing of 0.845 V peak-peak, which may be used for supply voltages of 2.5 V ±10%, 3.3 V ±10% or (2.25 V to 3.63 V). Alternatively, an order code of “GS corresponds to a VHn code “G (i.e. Vdd-1.193 V) and a VLn order code “S (e.g. Vdd-1.530 V) corresponding to a V_Swing of 0.760 V peak-peak, which may be used for a supply voltage of 3.3 V ±10%.

## **Notes:** 20. Top Marking: Y denotes manufacturing origin and XXXX denotes manufacturing lot number. The value of “Y will depend on the assembly location of the device. 21. A capacitor of value 0.1 µF or higher between VDD and GND is required. An additional 10 µF capacitor between VDD and GND is required for the best phase jitter performance.
