PRELIMINARY INFORMATION
ICS270
Triple PLL Field Programmable VCXO Clock Synthesizer
Description
The ICS270 field programmable VCXO clock synthesizer generates up to eight high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal input. It is designed to replace crystals and crystal oscillators in most electronic systems. Using ICS’ VersaClockTM software to configure PLLs and outputs, the ICS270 contains a One-Time Programmable (OTP) ROM for field programmability. Programming features include VCXO, eight selectable configuration registers and up to two sets of four low-skew outputs. Using Phase-Locked Loop (PLL) techniques, the device runs from a standard fundamental mode, inexpensive crystal, or clock.
