SET-TOP CLOCK SOURCE
Description
The MK2761 is a low-cost, low-jitter, high-performance
clock synthesizer for set-top box applications. Using
analog Phase-Locked Loop (PLL) techniques, the
device accepts a 27 MHz crystal or clock input to
produce multiple output clocks including the processor
clock, the UART clock, a selectable audio clock, and
four low skew copies of the 27 MHz. The audio clocks
are frequency-locked to the 27 MHz using our patented
zero ppm error techniques. This allows audio and video
to track exactly, thereby eliminating the need for large
buffer memory.
ICS manufactures a large variety of Set-top Box and
multimedia clock synthesizers for all applications.
Consult ICS to eliminate crystals and oscillators from
your board.
