3. GM5120
The gm5116/26 is a graphic processing IC for Liquid Crystal Display (LCD) monitors at XGA/SXGA
resolution. It provides all key IC functions required for the highest quality LCD monitors. On-chip
functions include a high-speed triple-ADC and PLL, Ultra-Reliable DVI
T M
receiver, a high quality
zoom and shrink scaling engine, an on-screen display (OSD) controller, digital color controls and an
on-chip microcontroller (OCM). With this level of integration, the gm5116/26 devices simplify and
reduce the cost of LCD monitors while maintaining a high-degree of flexibility and quality.
4. LVDS (THC63LVDM83A)
The THC63LVDM83A transmitter converts 28 bits 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. The HC63LVDM83A can be programmed for rising edge or
falling edge clocks through a dedicated pin. The THC63LVDF84A receiver converts the LVDS data
streams back into 28 bits of CMOS/TTL data with falling edge clock. At a transmit clock frequency of
85MHz, 24 bits of RGB data and 4 bits of LCD timing and control data (HSYNC, VSYNC, CNTL1,
CNTL2) are transmitted at a rate of 595 Mbps per LVDS data channel.
