The X98027 is a 275MHz triple video digitizer with a digital PLL. It contains all the components necessary to digitize analog RGB or YUV graphics signals from personal computers, workstations, and video set-top boxes. The fully differential analog design provides high PSRR and dynamic performance to meet the stringent requirements of the graphics display industry. The AFE's 275MSPS conversion rate supports resolutions up to QXGA at a 60Hz refresh rate, while the high input bandwidth ensures sharp images at the highest resolutions. To minimize noise, the X98027's analog section features 2 sets of pseudo-differential RGB inputs with programmable input bandwidth, as well as internal DC restore clamping (including mid-scale clamping for YUV signals). This is followed by the programmable gain/offset stage and the three 275MSPS analog-to-digital converters (ADCs). Automatic Black Level Compensation (ABLC™) eliminates part-to-part offset variation, ensuring perfect black level performance in every application. The X98027's digital PLL generates a pixel clock from the analog source.
