Description
The Si5013 is a fully-integrated, high-performance limiting amplifier (LA) and clock
and data recovery (CDR) IC for high-speed serial communication systems. It
derives timing information and data from a serial input at OC-12/3 and STM-4/1
rates. Use of an external reference clock is optional. Silicon Laboratories®
DSPLL⢠technology eliminates sensitive noise entry points, thus making the PLL
less susceptible to board-level interaction and helping to ensure optimal jitter
performance.
The Si5013 represents a new standard in low jitter, low power, small size, and
integration for high-speed LA/CDRs. It operates from a 3.3 V supply over the
industrial temperature range (â40 to 85 °C).
