Integrated Circuit Systems, Inc. ICS1523 High-Performance Programmable Line-Locked Clock Generator General Description The ICS1523 is a low-cost but very high-performance frequency generator for line-locked and genlocked highresolution video applications. Using ICS’s advanced low-voltage CMOS mixed-mode technology, the ICS1523 is an effective clock solution for video projectors and displays at resolutions from VGA to beyond UXGA. The ICS1523 offers pixel clock outputs in both differential (to 250 MHz) and single-ended (to 150 MHz) formats. Dynamic Phase Adjust™ circuitry allows user control of the pixel clock phase relative to the recovered sync signal. A second differential output at half the pixel clock rate enables deMUXing of multiplexed analog-to-digital converters.
