MK3712

3.3 V

-T

VCXO

Description

The MK3712 series of devices includes the original

MK3712S and the new MK3712D. The MK3712D is a

drop-in replacement for the MK3712S device.

Compared to the earlier device, the MK3712D offers

improved power supply noise rejection.

The MK3712 is a low cost, low jitter, high performance

3.3 Volt VCXO and PLL clock synthesizer designed to

replace expensive VCXOs and crystals used in Set-Top

Box applications. The patented 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

minimum. Using our analog Phase-Locked Loop (PLL)

techniques, the device uses an external, fundamental

mode 27.0 MHz pullable crystal input to produce output

clocks of 11.0592 MHz, 13.5 MHz, and 27 MHz.

ICS manufactures the largest variety of Set-Top Box

and mulitmedia clock synthesizers for all applications.

If more clock outputs are needed, see the MK277x

family of parts. Consult ICS to eliminate VCXOs,

crystals and oscillators from your board.

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.
