FEATURES
• Micro-power Bipolar technology
• Complies with Bellcore and ITU-T
specifications
• Supports 2.488 Gbps (OC-48)
• 8-bit LVDS data path
• Compact 100 TQFP/TEP package
• Diagnostic loopback mode

• Low jitter serial interface
• Single 3.3V supply
The S3042 SONET/SDH receiver chip is a fully
integrated deserialization SONET OC-48 (2.488
Gbps) interface device. The chip performs all
necessary serial-to-parallel and framing functions
in conformance with SONET/SDH transmission
standards. The device is suitable for SONET-
based ATM applications. Figure 1 shows a typical
network application.
The low jitter serial interface guarantees compliance
with the bit-error rate requirements of the Bellcore
and ITU-T standards. The S3042 is packaged in a
100 TQFP/TEP, offering designers a small package
outline.
