MK2771-15 VCXO and Set-Top Clock Source Description The MK2771-15 is a low cost, low jitter, high performance VCXO and clock synthesizer designed for set-top boxes. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3V input voltage to cause the output clocks to vary by ±100 ppm. Using ICS/MicroClock’s patented VCXO and analog Phase-Locked Loop (PLL) techniques, the device uses an inexpensive 13.5 MHz pullable crystal input to produce multiple output clocks including two selectable processor clocks, a selectable audio clock, two munications clocks, and three fixed clocks. All clocks are frequency locked to the 27.00MHz output (and to each other) with zero ppm error, so any...
