The ICS650-05 is a low cost, low jitter, high performance clock synthesizer designed to produce 74.175824 MHz and 74.250000 MHz as necessary for HDTV applications. Using our patented analog Phase-Locked Loop (PLL) techniques, the device uses a 27.0 MHz clock or fundamental crystal input to produce buffered, fixed clocks and a selectable frame rate clock for HDTV systems.
