Hot-selling and scarce AD9983AKSTZ-140 High Performance 8-Bit Display Interface LQFP80 spot stock

Product Descriptions

The AD9983A is a complete 8-bit, 170 MSPS, monolithicanalog interface optimized for capturing YPbPr video and RGBgraphics signals. Its 170 MSPS encode rate capability and fullpower analog bandwidth of 300 MHz support all HDTV videomodes up to 1080p as well as graphics resolutions up to UXGA(1600 x 1200 at 60 Hz).

The AD9983A includes a 170 MHz triple ADC with an internalreference, a PLL, and programmable gain, offset, and clampcontrol. The user provides only a 1.8 V power supply and ananalog input. Three-state CMOS outputs can be powered from1.8 V to 3.3 V.

The AD9983A on-chip PLL generates a sample clock from thetri-level sync (for YPbPr video) or the horizontal sync (for RGBgraphics). Sample clock output frequencies range from 10 MHzto 170 MHz. With internal coast generation, the PLL maintainsits output frequency in the absence of sync input. A 32-step​ sampling clock phase adjustment is provided . Output data,sync, and clock phase relationships are maintained.
