GenClockHSYNC to Video Clock
Description
The MK1573 GenClock™ provides genlock
timing for video overlay systems. The device
accepts the horizontal sync (HSYNC) signal as the
input reference clock, and generates a frequency-
locked high speed output. Stored in the device are
the multipliers for 16 combinations of popular
frequencies for analog and digital TV and set-top
box systems. Frequency-locked outputs include
1X, 4X, and 8X the subcarrier frequencies of
NTSC and PAL systems, and 27MHz plus
13.5MHz for digital video systems. In most
selections, the chip recovers the HSYNC clock by
outputting a low jitter 50% duty cycle version of
HSYNC. Also available is an inverted recovered
HSYNC clock, and a double speed recovered
HSYNC clock.
MicroClock can customize this device for any
other different frequencies.
Features
• Packaged in 16 pin narrow (150 mil) SOIC
• The -02 version has one frequency changed
(32MHz was added), and tracks the HSYNC
better than the -01 version.
• Exact ratios stored in the device eliminate the need
for external dividers
• Accepts HSYNC of 15.625kHz or 15.73426kHz
• Highly accurate frequency generation within 1 ppm
• Generates NTSC/PAL subcarrier frequencies, and
4X and 8X of those frequencies
• Generates 27MHz and 13.5MHz
• 2X HSYNC clock available
• Recovered HSYNC clock available
• Inverted HSYNC clock available
• 4.5V to 5.5V operation

External Components/Crystal Selection
The MK1573 requires a minimum number of external components for proper operation. A 0.1µF low
leakage capacitor (see Capacitor Selection on following page) should be connected between CAP1 and
CAP2 as close to the chip as possible. A high quality ceramic capacitor is recommended. A decoupling
capacitor of 0.1µF must be connected between VDD and GND pins (pins 2 and 3, 5 and 7) close to the
chip, and 33terminating resistors can be used on clock outputs with traces longer than 1 inch.

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.
2. Most selections have zero ppm error. Some selections have a maximum of 1 ppm synthesis error .
