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.

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.

I C R O C LOC K 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. MK3721 Low Cost 3.
