MK3721
Low Cost 3.3 Volt VCXO
Description
The MK3721 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 techniques,
the device uses an inexpensive external pullable
crystal in the range of 16.2 - 28 MHz to produce a
VCXO output clock at that same frequency.
ICS/MicroClock 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/MicroClock to eliminate
VCXOs, crystals and oscillators from your board.
Features
• Packaged in 8 pin SOIC
• 3.3 V operating voltage
• 16.2 MHz to 28 MHz operation
• Uses an inexpensive external crystal
• On-chip VCXO (patented) with pull range of
200 ppm (minimum)
• VCXO tuning voltage of 0 to 3.3 V
• 12 mA output drive capability at TTL levels
• Advanced, low power, sub-micron CMOS process
• For frequencies between 8 MHz to 16 MHz, use
the MK3711A. For frequencies between 1 MHz
and 8 MHz, use the MK3713. For higher than
28 MHz, use the MK3732-05
