Description
The MK2761A 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.
