38.88, 51.84 or 77.76 MHz
• Interface to both LVPECL and TTL logic
• Simple interface with 3.3 V or 5 V Optical
modules
• Directly compatible with 3.3 V or 5 V network
interface devices

• Compact 14 mm 80 PQFP package
• Diagnostic loopback mode
• Lock detect
• Low jitter LVPECL interface
• Single 3.3 V supply
The S3019 SONET/SDH transceiver chip is a fully
integrated serialization/deserialization SONET OC-12
(622.08 Mbit/s) and OC-3 (155.52 Mbps) 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 S3019
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 S3019 also per-
forms SONET/SDH frame detection. The chip can be
used with a 19.44, 38.88, 51.84 or 77.76 MHz refer-
ence clock, in support of existing system clocking
schemes.
The low jitter LVPECL interface guarantees compliance
with the bit-error rate requirements of the Bellcore
and ITU-T standards. The S3019 is packaged in a
14 mm 80 PQFP, offering designers a small package
outline.
