ICS271

Stresses above the ratings listed below can cause permanent damage to the ICS271. These ratings, which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.

The ICS271 field programmable VCXO clock synthesizer generates up to six 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 ICS271 contains a One-Time Programmable (OTP) ROM for field programmability. Programming features include VCXO, eight selectable configuration registers and up to two sets of three low-skew outputs.

Each of the two output groups are powered by a separate VDDO voltage. VDDO may vary from 1.8 V to VDD.

Using Phase-Locked Loop (PLL) techniques, the ICS271 runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace VCXOs, multiple crystals and oscillators, saving board space and cost.

The ICS271 is also available in factory programmed custom versions for high-volume applications.
