MK1604
Low Cost Video CD Clock Source
ICRO CLOC K
Description
Features
The MK1604 provides clocks for video CD
systems. It is designed to work with many popular
MPEG 1 decoder solutions and microcontrollers.
The chip uses MicroClock’s proprietary analog
Phase-Locked Loop technology, and generates all
of the outputs from a 16.9344MHz input crystal.
This chip eliminates multiple crystals and
• Packaged in 16 pin narrow (150 mil) SOIC
• Compatible with all popular MPEG I decoders
• Nine different microcontroller frequencies
selectable from 4 MHz to 32 MHz
oscillators in video CD systems, saving component
cost, component count, board stuffing cost, and
increasing reliability by removing mechanical
quartz devices from the system.
• Fixed clocks of 13.5, 27, and 40.5 MHz
• Power Down pin turns off some outputs
• All clocks are frequency-locked to each other
• Two outputs of 16.9344. Each can drive 2-3 loads
• 2.7V to 5.5V operation
MicroClock can customize this device for any
different frequencies for a small NRE.

External Components/Crystal Selection
The MK1604 requires a minimum number of external components for proper operation. For a crystal input,
a parallel resonant 16.9344 MHz, 18pF load, crystal is recommended. The frequency tolerance of the
crystal should be 50ppm or better. For a clock input, connect to X1 and leave X2 unconnected. VDD and
GND pins should be connected together, a decoupling capacitor of 0.1µF must be connected between
them very close to the chip, and 33Wterminating resistors should be used on clock outputs with traces
longer than 1 inch.

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.
2. Provided the crystal is properly tuned, or an accurate 16.9344 MHz input clock is used.
3. This spec applies only to the 32 and 23MHz controller clock selections.
