One of the components, the 8-bit CDK3404 offers a sampling frequency of 180MSPS making it ideal for display standards of 60Hz VGA (640 x 480), 72Hz SVGA (800 x 600), 75Hz XGA (1024 x 768), and 60Hz SXGA (1280 x 1024). It offers video signal conversion for RGB, YCBCR, and Composite, Y, C signals.

Operating from a single 3.3V supply the CDK3404 has additional circuitry for bi-level sync and blanking level generation. The current-steering DACs, 3401/2/3/4, have been specifically designed to produce standard video output levels when connected directly to a single-ended double-terminated 75-O coaxial cable.

High resolution, ease of use, and the extended temperature range of -40°C to +125°C will satisfy the requirements of applications which include LCD displays, medical ultrasound, automotive entertainment, ultra-mobile personal computers (UMPCs), mini-USB to VGA connectors, and other multimedia systems.
