3.3 VOLT SET-TOP BOX VCXO
MK3712
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.
