MK3724GLFTR

VCXO PLUS AUDIO CLOCK FOR
The MK3724 is a low cost, low jitter, high-performance VCXO and PLL clock synthesizer designed to replace expensive discrete VCXOs and multipliers. 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. Using IDT's analog/digital Phase-Locked Loop (PLL) techniques, the device uses an inexpensive 27 MHz pullable crystal input to produce a reference output and a selectable audio clock.
The frequency of the on-chip VCXO is adjusted by an external control voltage connected to VIN. Because VIN is a high impedance input, it can be driven directly from an PWM RC integrator circuit.
IDT manufactures the largest variety of VCXO-based timing devices for all applications. Consult IDT to eliminate VCXOs, crystals, and oscillators from your board.
