BROADCOM 25 MHZ LVDS CLOCK
Description
The ICS556-01 is a clock oscillator with LVDS outputs. Using a standard 25 MHz crystal, the device outputs a .25 mHz (reference) differential output clock. The operation voltage is 2.5 V to support today’s popular interfaces. The termination resistor is off-chip.
Features
Packaged in 8-pin TSSOP Requires no external components Low Phase Jitter: <1 ps from 10 kHz to 10 MHz Differential LVDS outputs Operating voltage of 2.5 V. Advanced, low power, sub-micron CMOS process
