MK2771-15

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 MK2771-15 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, MK2771-15 uses an inexpensive 13.5 MHz pullable crystal input of MK2771-15 to produce multiple output clocks including two selectable processor clocks, a selectable audio clock, two communications 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 output can be used as the VCXO output.
