SI5356
Overview
The Si5356 is a highly flexible, I2C programmable clock generator capable of synthesizing four completely non-integer related frequencies up to 200 MHz. The device has four banks of outputs with each bank supporting two CMOS outputs at the same frequency.
- Generates any frequency from 1 to
- 200 MHz on each of the 4 output banks Programmable frequency configuration
- Guaranteed 0 ppm frequency synthesis error for any combination of frequencies
- 25 or 27 MHz xtal or 5-200 MHz input clk Eight CMOS clock outputs Easy to use programming software
- Configurable “triple A” spread spectrum:
- any clock, any frequency, and with any
- spread amount Programmable output phase adjustment
- with resolution of 20 ps per step
- Interrupt pin indicates LOS or LOL OE pin disables all outputs or per bank OE control via I2C Low jitter: 50 ps pk-pk (typ), 100 ps pk-pk period jitter (max) Excellent PSRR performance eliminates need for external power supply filtering Low power: 45 mA Core VDD: 1.8, 2.5, or 3.3 V Separate VDDO for each bank of outputs: 1.8, 2.5, or 3.3 V Small size: 4x4 mm 24-QFN Industrial temperature range: -40 to +85 °C
