Description

The MK2754 is MicroClock’s lowest cost, low jitter, high performance VCXO and PLL clock synthesizer designed to replace expensive 54 MHz VCXOs. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3V input voltage to vary the output clocks by ±100 ppm. Using MicroClock’s patented VCXO and analog Phase-Locked Loop (PLL) techniques, the device uses an inexpensive external 13.5 MHz pullable crystal input to produce a 54 MHz output clock.
