Analog Interface The complete 8-bit, 170 MSPS, monolithic analog interface is optimized for capturing RGB graphics signals from personal computers and workstations. Its 170 MSPS encode rate capability and full-power analog bandwidth of 330 MHz support resolutions of up to 1600 × 1200 (UXGA) at 60 Hz. The interface includes a 170 MHz triple ADC with internal 1.25 V reference; a phaselocked loop (PLL); and programmable gain, offset, and clamp controls. The user provides only a 3.3 V power supply, analog input, and Hsync. Three-state CMOS outputs can be powered from 2.5 V to 3.3 V. The analog interface also offers full sync processing for composite s...
