THine THCS251 Instruction Manual

THCS251_Rev.3.01_E
General description
The THCS251 integrates Serializer and Deserializer
onto a single chip, which supports general purpose
input and output (GPIO) signals through two pairs of
differential signal.
GPIO sampling clock is selectable from external
reference clock or internal oscillator clock.
The 8B10B encoding and decoding adopted by
THCS251 is easy to connect to optical / wireless
communication devices with high robustness and DC
balanced signal.
The built-in adaptive equalizer enables flexible cable
selection.

Application

The THCS251 can applicable to any systems which
have many control signals between PCBs, for
example Multi-function printers, Amusement
machines, Factory Automation and TVs.
