The ICS627-01 is a low cost, low jitter, high
performance clock synthesizer which can generate
frequencies required for HDTV receivers and set-
top boxes. Using ICS’s patented analog/digital
Phase-Locked Loop (PLL) techniques, the device
uses an inexpensive fundamental 27 MHz crystal
input to produce low jitter HDTV pixel clocks. It
has a separate input for a 1001/1000 or
2(1001/1000) conversion from a 13.5 MHz,
27 MHz or 54 MHz input.
