MK3721

LOW COST 16.2 TO 28 MHZ 3.3 VOLT VCXO

Description

Features

The MK3721 series of devices includes the original

MK3721S and the new MK3721D. The MK3721D is a

drop-in replacement for the MK3721S device.

Compared to the earlier device, the MK3721D offers a

wider operating frequency range and improved power

supply noise rejection.

• MK3721D is a drop-in replacement for the earlier

MK3721S device

• Packaged in 8-pin SOIC

• Operational frequency range of 16.2 MHz to 28 MHz

• Uses an inexpensive external crystal

• On-chip patented VCXO with pull range of 200 ppm

The MK3721 is a low cost, low-jitter, high-performance

3.3 volt VCXO designed to replace expensive discrete

VCXOs 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’ patented VCXO techniques, the device uses an

inexpensive external pullable crystal in the range of

16.2 to 28 MHz to produce a VCXO output clock at that

same frequency.

(minimum)

• VCXO tuning voltage of 0 to 3.3 V

• Operating voltage of 3.3 V

• 12 mA output drive capability at TTL levels

• Advanced, low-power, sub-micron CMOS process

• For frequencies between 1 MHz and 8 MHz, use the

MK3713D. For higher than 28 MHz, use the

MK3732-05.

ICS 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 to eliminate

VCXOs, crystals, and oscillators from your board.

• Available in a lead-free package

MK3721D is recommended for new designs.

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

external control voltage input into pin VIN. Because

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

from an PWM RC integrator circuit. Frequency output

increases with VIN voltage input. The usable range of

VIN is 0 to 3.3 V.
