SI5355
Overview
The Si5355 is a highly flexible 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 Eight CMOS clock outputs Guaranteed 0 ppm frequency synthesis
- error for any combination of frequencies
- 25 or 27 MHz xtal or 5-200 MHz input clk
- Five programmable control pins (output
- enable, frequency select, reset) Separate OEB pins to disable individual
- banks or all outputs Loss of signal output
- Low 50 ps (typ) pk-pk period jitter
- Phase jitter: 2 ps rms 12 kHz-20 MHz Excellent PSRR performance eliminates need for external power supply filtering Low power: 45 mA (core) 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 Custom versions available using ClockBuilder™ web utility Samples available in 2 weeks
