HDTV CLOCK SYNTHESIZER
IDT™ / ICS™ HDTV CLOCK SYNTHESIZER
Description
The MK2716 is a low-cost, low jitter, high-performance PLL
clock synthesizer designed to produce the 74.176 MHz and
74.25 MHz clocks necessary for HDTV systems. Using
IDT’s patented analog Phase-Locked Loop (PLL)
techniques, the device accepts a 27 MHz crystal or clock
input. The zero ppm synthesis error exactly locks the
display to the digital stream.
IDT manufactures the largest variety multimedia clock
synthesizers for all applications. Consult IDT to eliminate
crystals and oscillators from your board.
For applications that require lower jitter, such as SDI and
pixel clocks, use the ICS664.

... Output 8 X2 External Components Decoupling Capacitor As with any high performance mixed-signal IC, the MK2716 must be isolated from system power supply noise to perform optimally. A decoupling capacitor of 0.01µF must be connected between VDD and GND on pins 2 and 3. It must be connected close to the MK2716 to minimize lead inductance ...
