1.16. IC8702 (RH-iXC150WJQZY)
The ICS275 field programmable VCXO clock synthesizer generates up to four high-quality, high-frequency clock outputs including multiple reference
clocks from a low-frequency crystal input. Using ICS’ VersaClockTM software to configure PLLs and outputs, the ICS275 contains a One-Time Pro-
grammable (OTP) ROM for field programmability. Programming features include VCXO, eight selectable configuration registers and up to two sets of
two low-skew outputs.
Using Phase-Locked Loop (PLL) techniques, the device runs from a standard fundamental mode, inexpensive crystal, or clock.
