Description
The S19252 MUX/DeMux chip is a fully
integrated serialization/de-serialization SONET
STS-192/10 GB Ethernet/Fiber Channel
transceiver with Electronic Dispersion
Compensation (EDC). This device can be used
to compensate channel impairments caused by
Single Mode Fiber (SMF) and copper medium.
The chip performs all necessary parallel-to-serial
and serial-to-parallel functions in conformance
with SONET/SDH, 10 Gigabit Ethernet (10 GbE)
and 10 Gigabit Fibre Channel (10 G FC)
transmission standards. The figure below shows
a typical network application. The other
application block diagrams are shown on
page 2.
On-chip clock synthesis PLL components are
contained in the S19252 chip, allowing the use
of a slower external transmit clock reference.
The chip can be used with 155.52 MHz or 622.08
MHz (or equivalent FEC/10 GbE/10 G FC rates)
reference clocks, in support of existing system
clocking schemes. The low-jitter LVDS interface
guarantees compliance with the bit-error rate
requirements of the Telcordia and ITU-T
standards.

Overview
The S19252 transceiver incorporates SONET/
SDH/10 GbE/10 G Fibre Channel serialization
and deserialization functions. This chip can be
used to implement the front end of SONET/10
GbE/10 G Fibre Channel equipment, which
consists primarily of the serial transmit interface
and the serial receive interface. The chip
includes parallel-to-serial, and serial-to-parallel
conversion and system timing.
Internal clocking and control functions are
transparent to the user.
Applications

Systems & Modules
• Section Repeaters
• Add Drop Multiplexers (ADM)
• Broad-Band Cross-Connects
• Fiber Optic Test Equipment
