LOW COST 27 MHZ 3.3 VOLT VCXO
IDT™ / ICS™ LOW COST 27 MHZ 3.3 VOLT VCXO
Description
The ICS721 is a low cost, low-jitter, high-performance 3.3
volt VCXO designed to replace expensive discrete VCXOs
modules. Using IDT’s patented VCXO techniques, the
device uses an inexpensive external pullable crystal in the
range of 16.2 to 28 MHz to produce a VCXO output clock at
that same frequency.
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 3.3
V.
IDT manufactures the largest variety of Set-Top Box and
multimedia clock synthesizers for all applications. Consult
IDT with your special requirements.
