Integrated Circuit Systems, Inc. User-Programmable Dual High-Performance Clock Generator Description The ICS2572 is a dual-PLL (phase-locked loop) clock gener- ator with differential video outputs specifically designed for high-resolution, high-refresh rate, video applications. The video PLL generates any of 16 pre-programmed ...
