HDTV Clock Synthesizer

The 667-01 is a low-cost, low jitter, high-performance PLL clock synthesizer designed to produce the 74.176 MHz clock necessary for HDTV systems. Using IDT's patented analog Phase-Locked Loop (PLL) techniques, the device accepts a 27 MHz crystal or clock input. The zero ppm synthesis error exactly locks the display to the digital stream. IDT manufactures the largest variety multimedia clock synthesizers for all applications. Consult IDT to eliminate crystals and oscillators from your board.
