GENERAL DESCRIPTION
The S3059 SONET/SDH transceiver chip is a fully
integrated serialization/deserialization SONET
OC-48 (2488.32 Mbps), OC-24 (1244.16 Mbps), Gi-
gabit Ethernet (1250 Mbps), OC-12 (622.08 Mbps)
and OC-3 (155.52 Mbps) interface device. 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 WDM applications. Figure 1 shows a
typical network application.
On-chip clock synthesis is performed by the high-
frequency Phase Locked Loop (PLL) on the S3059
transceiver chip allowing the use of a slower external
transmit clock reference. The chip can be used with
a 155.52 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 S3059 is pack-
aged in a 218 TBGA, offering designers a small
package outline.
