AD9984AKCPZ-140

The AD9984AKCPZ-140 is a 10-bit monolithic Analogue Interface optimized for capturing YPbPr video and RGB graphics signals. Its 170MSPS encode rate capability and full power analogue bandwidth of 300MHz support all HDTV video modes up to 1080p, as well as graphics resolutions up to UXGA (1600 x 1200 at 60Hz). The AD9984A includes a 170MHz triple ADC with an internal reference, a PLL and programmable gain, offset and clamp control. The user provides only a 1.8V power supply and an analogue input. Three-state CMOS outputs can be powered from 1.8 to 3.3V. The interface on-chip PLL generates a sample clock from the tri-level sync (for YPbPr video) or the horizontal sync (for RGB graphics). Sample clock output frequencies range from 10 to 170MHz. With internal coast generation, the PLL maintains its output frequency in the absence of a sync input.
