MK3200
32.768 kHz Clock Oscillator
Description
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.
Features
• 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

Notes: 1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the
device. Prolonged exposure to levels above the operating limits but below the Absolute Maximums may affect
device reliability.
External Components
The MK3200 requires a minimum number of external components for proper operation. A decoupling capacitor of
0.01µF should be connected between VDD and GND on pins 2 and 3, as close to the MK3200 as possible. A series
termination resistor of 33 may be used for the clock output if the trace is longer than a few inches. The input crystal
must be connected as close to the chip as possible. The input crystal should be a parallel mode watch crystal with 12
pF load capacitance.
