DescriptionSET TOP CLOCK SOURCE
The MK2761A is a low-cost, low-jitter, high-performance clock synthesizer for set-top box applications. Using analog Phase-Locked Loop (PLL) techniques, MK2761ASTR 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 ofMK2761ASTR 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.
