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.
By V-by-One
TM
technologies, unique encoding scheme
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.
