Description
The Si5600 is a complete low-power transceiver for high-speed serial
communication systems operating between 9.9 Gbps and 10.7 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 Si5600 operates from a single 1.8 V supply over the industrial temperature
range (–40
°
C to 85
°
C).
