GENERAL DESCRIPTION
The S3037 SONET/SDH transceiver chip is a fully
integrated serialization/deserialization SONET OC-12
(622.08 Mbit/s) and OC-3 (155.52 Mbit/s) interface de-
vice. The chip performs all necessary serial-to-parallel
and parallel-to-serial functions in conformance with
SONET/SDH transmission standards. The device is
suitable for SONET-based ATM applications. Figure
1 shows a typical network application.
On-chip clock synthesis is performed by the high-
frequency phase-locked loop on the S3037
transceiver chip allowing the use of a slower external
transmit clock reference. Clock recovery is performed
on the device by synchronizing its on-chip VCO directly
to the incoming data stream. The S3037 also per-
forms SONET/SDH frame detection. The chip can be
used with a 19.44 or 77.76 MHz reference clock, in
support of existing system clocking schemes.
The low jitter LVPECL interface guarantees compli-
ance with the bit-error rate requirements of the
Bellcore and ITU-T standards. The S3037 is pack-
aged in a 10 mm 64 PQFP, offering designers a small
package outline.
