LOW COST 3.3 VOLT VCXO
MK3723
Description
The MK3723 series of devices includes the original
MK3723S and the new MK3723D. The MK3723D is a
drop-in replacement for the MK3723S device.
Compared to the earlier device, the MK3723D offers a
wider operating frequency range and improved power
supply noise rejection.
The MK3723 is ICS’ low cost, low jitter, high
performance 3.3 volt VCXO designed to replace
expensive discrete VCXO modules. The on-chip
Voltage Controlled Crystal Oscillator accepts a 0 to
3.3V input voltage to cause the output clocks to vary by
±100 ppm. Using ICS’ patented VCXO techniques, the
device uses an inexpensive external pullable crystal in
the range of 16 - 28 MHz to produce a VCXO output
clock that is a divide by 2, 4, 6, or 8 of the crystal
frequency.
ICS manufactures the largest variety of Set-Top Box
and multimedia clock synthesizers for all applications.
If more clock outputs are needed, see the MK3732 or
MK377x family of parts. Consult ICS to eliminate
VCXOs, crystals, and oscillators from your board.
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.
Features
MK3723D is a drop-in replacement for the earlier
MK3723S device
Packaged in 8 pin SOIC
Operating voltage of 3.3 V (±5%)
VCXO Operational frequency range of 2 MHz to 14
MHz
Uses an inexpensive external crystal
On-chip patented VCXO with pull range of 200ppm
(minimum)
