PRELIMINARY INFORMATION

ICS525-07/08

LVCMOS User Configurable Clock

Description

Features

• Packaged as 28-pin SSOP (150 mil body)

• Available in Pb (lead) free package

The ICS525-07/08 are the most flexible way to

generate a high-quality clock output from an

inexpensive crystal or clock input at low supply

voltages. The user can configure the device to produce

nearly any output frequency from any input frequency

by grounding or floating the select pins or by driving or

hard wiring the select pins high or low. Neither

microcontroller, software, nor device programmer are

needed to set the frequency. Using Phase-Locked

Loop (PLL) techniques, the device accepts a standard

fundamental mode, inexpensive crystal to produce

output clocks up to 250 MHz. It can also produce a

highly accurate output clock from a given input clock,

keeping them frequency locked.

• User determines the output frequency by setting all

internal dividers

• Eliminates need for custom oscillators

• Low voltage operation

• Pull-ups on all select inputs

• Input crystal frequency of 5 - 27 MHz

• Input clock frequency of 2 - 50 MHz

• Compensated loop bandwidth

• Enhanced low frequency operation (-08 version)

• Low jitter

For similar capability with a serial interface, use the

ICS307.

• Duty cycle of 45/55 up to 200 MHz

• Operating voltage of 1.8 V to 2.5 V

• Ideal for oscillator replacement

This product is intended for clock generation. It has low

output jitter (variation in the output period), but input to

output skew is not defined nor guaranteed.

• Available in commercial and industrial temperature

ranges
