Description
The MK3725 is a low cost, high-performance, two output 3.3 Volt VCXO and PLL clock synthesizer designed to replace expensive VCXOs and crystals. The patented on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3.3 V input voltage to cause the output clocks to vary by ±115 ppm minimum. Using our analog Phase Locked Loop (PLL) techniques, the device uses an external, fundamental mode pullable crystal input to produce output clocks of 2x the input frequency.
