THC63LVD823_Rev2.0
THC63LVD823
Single(135MHz)/Dual(170MHz) Link LVDS Transmitter for SXGA/SXGA+/UXGA
General Description
The THC63LVD823 transmitter is designed to support
Single Link transmission between Host and Flat Panel
Display up to SXGA+ resolutions and Dual Link trans-
mission between Host and Flat Panel Display up to
UXGA resolutions.
The THC63LVD823 converts 48bits of CMOS/TTL
data into LVDS(Low Voltage Differential Signaling)
data stream. The transmitter can be programmed for ris-
ing edge or falling edge clocks through a dedicated pin.
In Single Link, the transmit clock frequency of
135MHz, 48bits of RGB data are transmitted at an
effective rate of 945Mbps per LVDS channel. Using a
135MHz clock, the data throughput is 472Mbytes per
second.
In Dual Link, the transmit clock frequency of 85MHz,
48bits of RGB data are transmitted at an effective rate
of 595Mbps per LVDS channel. Using a 85MHz clock,
the data throughput is 595Mbytes per second.
