275MHz Triple Video Digitizer with Digital PLL
The X98027 3-channel, 8-bit Analog Front End (AFE) 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 60Hz refresh rate, while the front end's 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 www.DataSheet4U.com analog source's HSYNC or SOG (Sync-On-Green) signals. Pixel clock output frequencies range from 10MHz to 275MHz with sampling clock jitter of 250ps peak to peak.
Features
• 275MSPS maximum conversion rate • Low PLL clock jitter (250ps p-p @ 275MSPS) • 64 interpixel sampling positions • 0.35Vp-p to 1.4Vp-p video input range • Programmable bandwidth (100MHz to 780MHz) • 2 channel input multiplexer • RGB and YUV 4:2:2 output formats • 5 embedded voltage regulators allow operation from single 3.3V supply and enhance performance, isolation • Completely independent 8 bit gain/10 bit offset control • CSYNC and SOG support • Trilevel sync detection • 1.2W typical PD @ 275MSPS • Pb-free plus anneal available (RoHS compliant)
Applications
• LCD Monitors and Projectors • Digital TVs • Plasma Display Panels • RGB Graphics Processing • Scan Converters
