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 (–40 to 85 °C).
