General Description

The ICS1532 is a high-performance, cost-effective, 3-channel, 8-bit analog-to-digital converter with an integrated line-locked clock generator. They are part of a family of chips for high-resolution video applications that use analog inputs, such as LCD monitors, projectors, plasma displays, and HDTVs. Using low-voltage CMOS mixed-signal technology, they are an effective data-capture solution for VGA to UXGA.
