MK3727

LOW COST 24 - 36 MHZ 3.3 VOLT VCXO

VIN is a high impedance input, it can be driven directly

from an PWM RC integrator circuit. Frequency output

Description

increases with VIN voltage input. The usable range of

VIN is 0 to 3V.

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.

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

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. The MK3727 is

designed primarily for data and clock recovery

• Uses an inexpensive 12 to 18 MHz external crystal

• Ideal for ADSL applications using 17.664 MHz

external pullable crystal to generate locked 35.328

MHz clock physical layer clock

applications within end products such as ADSL

modems, set-top box receivers, and telecom systems.

• Ideal for set-top box applications using 13.5 MHz

external pullable crystal to generate lock 27 MHz

clock transport video clock

The MK3727D is recommended for new designs. The

MK3727D exhibits a moderate VCXO gain of

120ppm/V typical, when used with a high quality

external pullable quartz crystal. The MK3727C offers a

higher VCXO gain of 150ppm/V, similar to the earlier

MK3727A. The higher intrinsic VCXO gain of the

MK3727C may help compensate for the reduced

pullability of a low quality crystal used in some

applications. However, higher VCXO gain may also

increase clock output phase noise.

• On-chip VCXO with guaranteed pull range of ±115

ppm minimum (MK3727D)

• VCXO input tuning voltage 0 to 3.3 V

• Packaged in 8 pin SOIC (150 mil wide)

MK3727D is Recommended for New Designs.

The frequency of the on-chip VCXO is adjusted by an

external control voltage input into pin VIN. Because
