THCV220_16 Datasheet, PDF (5/18 Pages) THine Electronics, Inc. – THCV220 is designed to support video data transmission between the host and display.

Functional Description
Functional Overview
With V-by-One^® HS proprietary encoding scheme and CDR (Clock and Data Recovery) architecture,
THCV220 enable transmission of 8/10 bit RGB, 2bits of user-defined data (CONT), synchronizing signals
HSYNC, VSYNC, and DE by a pair cable with minimal external components.
THCV220 automatically extracts the clock from the incoming data streams and converts the serial data into
video data with DE being high or synchronizing data with DE being low, recognizing which type of serial data is
being sent by the transmitter. And it outputs the recovered data in the form of CMOS/TTL data.
THCV220 can operate for a wide range of a serial bit rate from 600Mbps to 3.75Gbps.
It does not need any external frequency reference, such as a crystal oscillator.
Internal Reference Output/Input Function (CAPOUT,CAPINA)
An internal regulator produces the 1.2V (CAPOUT). This 1.2V linear regulator can not supply any other
external loads. Bypass CAPOUT to GND with 2.2uF.
CAPINA supplies reference voltage for any internal analog circuit also. Bypass CAPINA to GND with 0.1uF
to remove high frequency noise. CAPOUT and CAPINA must be tied together.
Analog power supply AVCC is supposed to be stabilized with de-coupling capacitor and series noise filter (for
example, ferrite bead).
