MULTI-RATE SONET/SDH CDR IC WITH LIMITING AMPLIFIERThe 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). By Silicon Laboratories
