THCV213 and THCV214

LVDS SerDes transmitter and receiver

General Description

THCV213 and THCV214 is designed to support a pixel

data transmission between the Host and Display. The

chipset can transmit 18bit data and 4bit control data

through only a single differential cable at pixel clock

frequency from 5MHz to 40MHz.

and proprietary CDR technique, a link synchlonization

is achieved without any frequency reference such as

crystal oscillator. It drastically improves the cost and

size of the display system.

THCV213 transmitter converts the data into a single

LVDS serial data stream with embedded clock. It sup-

ports pre-emphasis mode for long cable transmission.

THCV214 receiver extracts the clock from the embed-

ded clock and transforms the serial data stream back

into the parallel data.

To confirm the reliability of link, several functions are

supported. THCV213 can transmit a INIT pattern to

establish a link if INIT sequence is required. THCV214

indicates the LOCK status.
