ICS556-01
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
