IDT, Integrated Device Technology Inc MK3727HLF

Description
The MK3727H is a low-drive, low-cost, single-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 ±115ppm minimum. Using analog Phase Locked Loop (PLL) techniques, the device uses an external, fundamental mode 13.5 MHz pullable crystal input to produce output clocks of 27 MHz. The drive parameters are optimized for low EMI.
