The Si5100 is a complete low-power transceiver for high-speed serial communication systems operating between OC-48 and 2.7 Gbps.
The receive path consists of a fully-integrated limiting amplifier, clock and data recovery unit
(CDR), and 1:16 deserializer.
The transmit path combines a low-jitter clock multiplier unit (CMU) with a 16:1 serializer.
The CMU uses Silicon Laboratories’ DSPLL technology to provide superior jitter performance while reducing design complexity by eliminating external loop filter components.
To simplify BER optimization in long-haul applications, programmable slicing and sample phase
adjustment are supported.
The Si5100 operates from a single 1.8 V supply over the industrial temperature range (–20 to 85 °C).
