MULTI-RATE SONET/SDH CDR IC WITH LIMITING AMPLIFIER

The SI5023 is a fully-integrated, high-performance limiting amp 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-48/12/3, STM-16/4/1, or Gigabit Ethernet (GbE) rates. Support for 2.7 Gbps data streams is also provided for OC-48/STM-16 applications that employ forward error correction (FEC). 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 SI5023 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).
