MK3754
Low Cost 54 MHz 3.3 Volt VCXO
Description
Features
The MK3754 is ICS/Microclock’s lowest cost, low
jitter, high performance 3.3 Volt VCXO and PLL
clock synthesizer designed to replace expensive
54 MHz VCXOs. The on-chip Voltage Controlled
Crystal Oscillator accepts a 0 to 3.3 V input voltage
to vary the output clocks by ±100 ppm. Using
ICS/Microclock’s patented VCXO and
analog/digital Phase-Locked Loop (PLL)
techniques, the device uses an inexpensive external
13.5 MHz pullable crystal input to produce a
54 MHz output clock.
The MK3754A is a drop-in replacement to the
earlier MK3754S.
• Packaged in 8 pin SOIC
• 3.3 V only operating voltage
• Uses an inexpensive 13.500 MHz external crystal
• On-chip VCXO (patented) with pull range of
200ppm (minimum)
• VCXO tuning voltage of 0 to 3.3 V
• 12mA output drive capability at TTL levels
• Advanced, low power, sub-micron CMOS process
• The A version is the latest, manufactured in a
smaller geometry process. The MK3754A gives a
wider pull range than the MK3754S, and so is
recommended for all new designs, and cost
reductions of existing designs.
