MK0220
Video CD Clock Source
Description
Features
The MK0220 provides clocks for video CD
systems. It is designed to work specifically with
the C-Cube CL480, and supports audio DAC’s
like the Crystal CS4333, and NTSC/PAL
encoders such as Brooktree’s Bt851.
• Packaged in 16 pin narrow (150 mil) SOIC
• Fully compatible with C-Cube CL480
• Supports Crystal Semiconductor’s CS4333
• Supports timing for Bt851 NTSC/PAL encoder
• CD clock input eliminates crystals and oscillators
• All clocks are frequency-locked to the CD clock
• 2.7V to 5.5V operation
The chip uses MicroClock’s proprietary analog
Phase-Locked Loop technology, and locks to the
CD output reference clock of 2.1168 MHz to
produce four output clocks.
MicroClock can customize this device for any
different frequencies for a small NRE.
• Zero ppm error 16.9344, 13.5, 27.0 MHz clocks
• Power down mode reduces IDD to 10µA (typ)

Note on reference input - the MK0220 is
designed to be used with a clock input into
pin 3. This clock will come from the CD kit.
While the chip can also be used with a
2.1168 MHz crystal, this is not a commonly
stocked value. If a 2.1168 MHz clock is not
available, contact MicroClock for other
devices.

External Components
The MK0220 requires a minimum number of external components for proper operation. Decoupling
capacitors of 0.1µF should be connected between VDD and GND on pins 4/5 and pins 13/12, as close to
the MK0220 as possible. A series termination resistor of 33Wmay be used for each clock output. The device
does not require (nor do we recommend) capacitors connected to the crystal pins. If a 2.1168 MHz crystal
is used, it must be connected as close to the chip as possible. Recommended load capacitance for the crystal
is 12pF.
