APPLICATIONS
GENERAL DESCRIPTION
The S3091 SONET/SDH MUX chip is a fully inte-
grated serializer with SONET OC-192 with FEC and
Digital Wrapper (9.953 to 10.709 Gbps) rate capabil-
ity. The chip performs all necessary parallel-to-serial
functions in conformance with SONET/SDH/Digital
Wrapper transmission standards. The device is suit-
able for SONET-based ATM applications. Figure 1
shows a typical network application.
On-chip clock synthesis PLL components are con-
tained in the S3091 MUX chip, allowing the use of a
slower external transmit clock reference. The chip can
be used with a 155.52 or 622.08 MHz reference clock
(or equivalent FEC or DW rate), in support of existing
system clocking schemes.
