LOW COST 27 MHZ VCXO
IDT™ LOW COST 27 MHZ VCXO
Description
The MK2727 is IDT’s lowest cost, low-jitter,
high-performance VCXO and PLL clock synthesizer
designed to replace expensive 27MHz 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 the largest 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. Consult IDT to eliminate VCXOs, crystals
and oscillators from your board.
