MK3715
LOW COST 3.3 VOLT VCXO
Description
The MK3715 is a low 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’
patented VCXO techniques, the device uses an
inexpensive external 13.5 MHz pullable crystal to
produce two fixed clock outputs of 54.0 MHz and 108.0
MHz.
ICS manufactures a large variety of Set-Top Box and
multimedia clock synthesizers for all applications. If
more clock outputs are needed, see the MK2731 or
MK377x family of parts. Consult ICS to eliminate
VCXOs, crystals and oscillators from your board.
