描述 Description

The MK2732-05 is a low cost, low jitter, high performance VCXO and PLL clock synthesizer designed to replace expensive discrete VCXOs and multipliers. The on-chip Voltage Controlled Crystal Oscillator (VCXO) accepts a 0 to 3 V 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 10 MHz to 14.318 MHz pullable crystal input to produce one or two output clocks.
