• Manufacturer Part Number: S3038
• Description: Sonet/sdh/atm OC-12 Quad Transceiver
• Manufacturer: AMCC (Applied Micro Circuits Corp)

S3040 OVERVIEW
The S3040 supports clock recovery for the OC-48/
STM-16 data rate. Differential serial data is input to
the chip at the specified rate and clock recovery is
performed on the incoming data stream. An external
oscillator is required to minimize the PLL lock time and
provide a stable output clock source in the absence of
serial input data. Retimed data and clock are output
from the S3040.
