PRELIMINARY INFORMATION
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
Zero ppm error 16.9344, 13.5, 27.0 MHz clocks
Power down mode reduces IDD to 10A (typ)
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.
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.
