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 to 85 °C).
