MK3200STR General Description

32.768KHZ CLOCK OSCILLATO
The MK3200 is IDT's lowest cost, low power clock oscillator that generates a low power 32.768 kHz output from an inexpensive 32.768 kHz crystal. This part includes a power down pin and allows you to tri state the output clock for in-circuit testing.

IDT 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 IDT to eliminate VCXOs, crystals and oscillators from your board.

Packaged in 8 pin SOIC or 8-pin MSOP (3.00 mm body)

8-pin MSOP available in Pb (lead) free package

Operates from 2.5 V to 5 V

Consumes only 3.5 A 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 IDT

MK3230 General Description

The MK3230 is the smallest size, lowest power system clock synthesizer available. It is the ideal way to generate clocks for portable computers, PDAs, and other devices where low power is required. Using analog Phase-Locked Loop (PLL) techniques, the device operates from a single 32.768 kHz crystal to produce the 32.768kHz, CPU, system, keyboard controller, and floppy (or super I/O) controller output clocks.

The device has two power down modes. From the CPU decoding table (when FS0, FS1, and FS2 all are low), the CPU and 14.3 MHz system clocks can be turned off. Also, the keyboard and 24 MHz peripheral clocks can be shut off from <a href="#" style="text-decoration:overline;">PD24+KBD</a> (pin 10). The part has a separate VDD32 pin for the 32 kHz clock, allowing it to run at a different voltage (down to 2.0V) from the rest of the chip, allowing it to run from a back-up
