Functional Overview

With High Speed CML SerDes, proprietary encoding scheme and CDR (Clock and Data Recovery) architecture,

THCV233 and THCV234 enable transmission of 24/32bit video data, 2bit control data and Data Enable (DE)

through high speed serial line by single/dual differential pair cable with minimal external components.

THCV233, LVDS data (including video data, control data and DE) and serializes video data and control data

separately, depending on polarity of DE. DE is a signal which indicates whether video or control data are active.

When DE is high, it serializes video data inputs into CML data streams. And it transmits serialized control data

when DE is low. Instead of DE in the LVDS format, THCV233 has DEIN LVCMOS-input pin, which enables to

transfer LVDS input data with external DE input via DEIN.

THCV234, automatically extracts clock from the incoming data streams and converts high-speed serial data into

video data with DE being high or control data with DE being low, recognizing which type of serial data is being

sent by transmitter. And it outputs the recovered data in the form of LVDS data. THCV234 has DEOUT output pin

which transmits DE signal in LVCMOS. THCV234 can seamlessly operate for a wide range of a serial bit rate

from 270Mbps to 3.4Gbps/lane.
