1 / 29 page  FN8217 Rev 3.00 Page 1 of 29 March 8, 2006 FN8217 Rev 3.00 March 8, 2006 X98014 140MHz Triple Video Digitizer with Digital PLL DATASHEET The X98014 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 140MSPS conversion rate supports resolutions up to SXGA at 75Hz refresh rate, while the front end's high input bandwidth ensures sharp images at the highest resolutions. To minimize noise, the X98014'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 140MSPS 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 X98014's digital PLL generates a pixel clock from the analog source's HSYNC or SOG (Sync-On-Green) signals. Pixel clock output frequencies range from 10MHz to 140MHz with sampling clock jitter of 250ps peak to peak. Features • 140MSPS maximum conversion rate • Low PLL clock jitter (250ps p-p @ 140MSPS) • 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 • 990mW typical PD @ 140MSPS • Pb-free plus anneal available (RoHS compliant) Applications • LCD Monitors and Projectors • Digital TVs • Plasma Display Panels • RGB Graphics Processing • Scan Converters Simplified Block Diagram RGB/YPbPrIN 1 PGA 8 bit ADC Offset DAC ABLC™ 8 or 16 x3 SOGIN1/2 HSYNCIN1/2 VSYNCIN1/2 Sync Processing Digital PLL Voltage Clamp RGB/YPbPrIN 2 3 3 RGB/YUVOUT PIXELCLKOUT HSOUT HSYNCOUT AFE Configuration and Control VSYNCOUT + NOT RECOMMENDED FOR NEW DESIGNS - THE ISL98001-140 IS A 100% COMPATIBLE IMPROVED ALTERNATIVE |
