LOW COST 27 MHZ 3.3 VOLT VCXO
IDT™ / ICS™ LOW COST 27 MHZ 3.3 VOLT VCXO
Description
The ICS722 is a low cost, low-jitter, high-performance 3.3
volt VCXO designed to replace expensive discrete VCXOs
modules. The on-chip Voltage Controlled Crystal Oscillator
accepts a 0 to 3.3 V input voltage to cause the output
clocks to vary by over ±100 ppm. 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 to eliminate VCXOs, crystals, and oscillators from your
board.
