LOW COST 24 TO 36 MHZ 3.3 VOLT VCXO
PRELIMINARY INFORMATION
Description
The ICS3727XP combines the functions of a VCXO
(Voltage Controlled Crystal Oscillator) and PLL
(Phase-Locked Loop) frequency doubler onto a single
chip. It is designed primarily for data and clock recovery
applications within end products such as set-top box
receivers.
The ICS3727XP exhibits a moderate VCXO gain of 200
ppm/V typical, when used with a high quality external
pullable quartz crystal.
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.
Features
ICS3727XP offers 24 to 36 MHz output frequency
range (output frequency = 2x crystal frequency) and
improved power supply noise rejection
Uses an inexpensive 12 to 18 MHz external crystal
Ideal for DV CODEC applications using 27 MHz
external pullable crystal with extended pull range to
generate locked 27 MHz clock transport video clock
On-chip VCXO with guaranteed pull range of ±200
ppm minimum
VCXO input tuning voltage 0 to 3.3 V
Packaged in 8-pin SOIC (150 mil wide)
