MK2772-01 Datasheet (Integrated Circuit Systems)

MK2772-01, VCXO and Set-Top Clock Source

The MK2772-01 is a low cost, low jitter, high performance VCXO and clock synthesizer for settop 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 Loop (PLL)
