3. GM5120
The gm5110/20 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
(OSD) controller, digital color controls and an on-chip microcontroller (OCM). With this level of integration, the
gm5110/20 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.
