Si5010
Description
The Si5010 is a fully integrated low-power clock and data recovery (CDR)
IC designed for high-speed serial communication systems. It extracts
timing information and data from a serial input at OC-12/3 or STM-4/1 data
rates. DSPLL™ technology eliminates sensitive noise entry points thus
making the PLL less susceptible to board-level interaction and helping to
ensure optimal jitter performance in the application.
The Si5010 represents an industry-leading combination of low jitter, low
power, and small size for high speed CDRs. It operates from a single 2.5 V
supply over the industrial temperature range (–40°C to 85°C).
