LOW COST 24 TO 36 MHZ 3.3 VOLT VCXO
Description
The MK3727D combines the functions of a VCXO (Voltage
Controlled Crystal Oscillator) and PLL (Phase Locked
Loop) frequency doubler onto a single chip. Used in
conjunction with an external pullable quartz crystal, this
monolithic integrated circuit replaces more costly hybrid
(canned) VCXO devices. The MK3727D is designed
primarily for data and clock recovery applications within end
products such as ADSL modems, set-top box receivers,
and telecom systems.
The frequency of the on-chip VCXO is adjusted by an
external control voltage input into pin VIN. Because VIN is a
high impedance input, it can be driven directly from an
PWM RC integrator circuit. Frequency output increases
with VIN voltage input. The usable range of VIN is 0 to 3 V.
