THC63LVDM83R/THC63LVDM63R

REDUCED SWING LVDS 24Bit/18Bit COLOR HOST-LCD PANEL INTERFACE

General Description

The THC63LVDM83R transmitter converts 28bits of

CMOS/TTL data into LVDS (Low Voltage Differential

Signaling) data stream. A phase-locked transmit clock

is transmitted in parallel with the data streams over a

fifth LVDS link. At a transmit clock frequency of

85MHz, 28bits of RGB data and 4bits of LCD timing

and control data (HSYNC, VSYNC, CNTL1, CNTL2)

are transmitted at a rate of 595Mbps per LVDS channel.

Also available is THC63LVDM63R that converts 21bits

of CMOS/TTL data into LVDS(Low Voltage Differential Signaling) data stream. Both transmitters can be

programmed reduced swing LVDS through a dedicated

pin for low power consumption and EMI.
