MK3727 - LOW COST 24 - 36 MHZ 3.3 VOLT VCXO

General Description

The MK3727 series of devices include the original MK3727S, MK3727A, and the new MK3727C and MK3727D.

The MK3727D and MK3727C are drop-in replacements for the MK3727S and MK3727A devices.

Key Features

  • MK3727D and MK3727C are drop-in upgrades to the earlier MK3727S and MK3727A devices.
  • MK3727D and MK3727C offer 24-36 MHz output frequency range (output frequency = 2x crystal frequency) and improved power supply noise rejection.
  • Uses an inexpensive 12 to 18 MHz external crystal.
  • Ideal for ADSL.

MK3727 LOW COST 24 - 36 MHZ 3.3 VOLT VCXO Description The MK3727 series of devices include the original MK3727S, MK3727A, and the new MK3727C and MK3727D. The MK3727D and MK3727C are drop-in replacements for the MK3727S and MK3727A devices. Compared to these earlier devices the MK3727D and MK3727C offer a wider operating frequency range and improved power supply noise rejection. The MK3727D is recommended for new designs. The MK3727 series combines the functions of a VCXO (Voltage Controlled Crystal Oscillator) and PLL (Phase Locked Loop) frequency doubler onto a single chip. Used in conjunction with an external pullable quartz crystal, this monolithic integrated circuit replaces more costly hybrid (canned) VCXO devices.
