MK2771-12 Datasheet (Integrated Circuit Systems)

MK2771-12, VCXO and Set-Top Clock Source

The MK2771-12 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 MicroClock’s patented VCXO and analog Phase-Locked
