MK3713 Datasheet, PDF (1/4 Pages) Integrated Circuit Systems – Low Cost 3.3 Volt VCXO

PRELIMINARY INFORMATION
MK3713
Low Cost 3.3 Volt VCXO
Description
The MK3713 is ICS/MicroClock’s lowest cost,
low jitter, high performance 3.3 Volt VCXO
designed to replace expensive VCXO 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 ±100 ppm. Using
ICS/MicroClock’s patented VCXO and analog
Phase-Locked Loop (PLL) techniques, the device
uses an inexpensive external pullable crystal input
to produce the output clock.
ICS/MicroClock manufactures the largest variety
of communications, 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/MicroClock to eliminate VCXOs, crystals
and oscillators from your board.
Features
