HIGH PERFORMANCE VCXO
ICS3726-12
PRELIMINARY INFORMATION
Description
The ICS3726-12 is a low cost, low-jitter,
high-performance 3.3 volt VCXO designed to replace
expensive discrete VCXOs modules. The ICS3726-12
offers a wider operating frequency range and improved
power supply noise rejection. The on-chip Voltage
Controlled Crystal Oscillator accepts a 0 to 3.3 V input
voltage. Using ICS’ patented VCXO techniques, the
device uses an inexpensive external pullable crystal in
the range of 20 to 52 MHz to produce a VCXO output
clock at that same frequency.
This part is ideal for Set-Top Box, multimedia clock
synthesizers and ADSL/VDSL applications.
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 VDD.
