SI5013

Si5013 OC-12/3, STM-4/1 SONET/SDH CDR IC WITH LIMITING AMPLIFIER Features High-speed clock and data recovery device with integrated limiting amplifier: Supports OC-12/3, STM-4/1 Loss-of-signal level alarm DSPLL® technology Data slicing level control Jitter generation 2.3 mUIrms (typ) Small footprint: 5 x 5 mm 10 mVPP differential sensitivity 3.3 V supply Reference and reference-less operation supported Applications SONET/SDH/ATM routers Add/drop multiplexers Digital cross connects Board level serial links SONET/SDH test equipment Optical transceiver modules SONET/SDH regenerators 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). Functional Block Diagram LTR LOS DSQLCH VDD DIN+ DIN– VDD Ordering Information: See page 22.
