ICS722
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 ICS’ 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.
ICS manufactures the largest variety of Set-Top Box
and multimedia clock synthesizers for all applications.
Consult ICS to eliminate VCXOs, crystals, and
oscillators from your board.
