Data Sheet
S19237 OVERVIEW
The S19237 transceiver incorporates SONET/SDH/10
Gigabit Ethernet serialization and deserialization func-
tions. This chip can be used to implement the front end
of SONET/10 Gigabit Ethernet equipment, which con-
sists primarily of the serial transmit interface and the
serial receive interface. The chip includes parallel-to-
serial, and serial-to-parallel conversion and system
timing. The system timing circuitry consists of high-
speed phase detectors, clock dividers, and clock distri-
bution throughout the front end.The sequence of
operations is as follows:
Transmitter Operations
1.
16-bit parallel input
2.
Parallel-to-serial conversion
3.
Serial data output
Receiver Operations
1.
Serial input to limiting post-amp
2.
Inter Symbol Interference (ISI) compensation
3.
Limiting amplifier
4.
Threshold adjustment
5.
Clock and Data recovery
6.
Phase adjustment for improved BER
7.
Serial-to-parallel conversion
8.
16-bit parallel data and clock output
