Description

Features

The MK3200 is ICS’ lowest cost, low power clock

oscillator that generates a low power 32.768 kHz

output from an inexpensive 32.768 kHz watch crystal.

This part includes a power down pin and allows you to

tri state the output clock for in-circuit testing.

ICS manufactures the largest variety of clock

synthesizers for all applications. If more clock outputs

are needed, including MHz frequencies, see the

MK32xx family of parts. Consult ICS to eliminate

VCXOs, crystals and oscillators from your board.

• Packaged in 8 pin SOIC

• Operates from 2.5 V to 5 V

• Consumes only 3.5 µA in normal operation

• Accepts an inexpensive 32.768 kHz crystal input

• Offers power down mode

• Includes an Output Enable pin to tri state

the output for in-circuit testing

• Advanced, low power, sub-micron CMOS process

• For other 32.768 kHz-based clocks with MHz

outputs, please consult ICS

• Industrial temperature version available
