This datasheet describes the AD9886, an 8-bit 140 MSPS monolithic analog interface for capturing RGB graphics signals from PCs and workstations.
The AD9886 is a complete 8-bit 140 MSPS monolithic analog interface optimized for capturing RGB graphics signals from personal computers and workstations. It features a 140 MHz triple ADC with an internal 1.25 V reference and a PLL to generate a pixel clock from an HSYNC signal. The device supports resolutions up to SXGA (1280 × 1024 at 75 Hz) and is fully programmable via a 2-wire serial interface.
