MK2727S

LOW COST 27 MHZ VCXO
The MK2727 is a low cost, low jitter, high-performance VCXO and PLL clock synthesizer designed to replace expensive 27 MHz VCXOs. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3V input voltage to cause the output clocks to vary by ±100 ppm. Using IDT'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 27 MHz output clock.

IDT manufactures a large variety of Set-Top Box and multimedia clock synthesizers for all applications. If more clock outputs are needed, see the MK2731 or MK277x family of parts.
