• < 2.0 Watt per set typically
The S3017/S3018 SONET/SDH/ATM transmitter and
receiver chips are fully integrated serialization/
deserialization SONET OC-12 (622.08 Mbit/s) interface
devices. With architecture developed by PMC-Sierra,
Inc., the chipset performs all necessary serial-to-paral-
lel and parallel-to-serial functions in conformance with
SONET/SDH transmission standards. The devices are
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 S3017 transmitter
chip allowing the use of a slower external transmit clock
reference. Clock recovery is performed on the S3018
receiver chip by synchronizing its on-chip VCO directly
to the incoming data stream. The S3018 also performs
SONET/SDH frame detection. The chipset can be used
with a 19.44 or 77.76 MHz reference clock, in support of
existing system clocking schemes.
The low jitter PECL interface guarantees compliance
with the bit-error rate requirements of the Bellcore,
ANSI, and ITU-T standards. The S3017 and S3018 are
packaged in a compact 52 PQFP, offering designers a
small package outline.
