210MHz Triple Video Digitizer With Digital PLL
The X98021 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 AFEs 210MSPS conversion rate supports resolutions up to UXGA at 75Hz refresh rate, while the front end's high input bandwidth ensures sharp images at the highest resolutions.
To minimize noise, the X98021 '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 210MSPS 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 X98021 '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 210MHz with sampling Clock jitter of 250ps peak to peak.
