LOW COST 8 - 16 MHZ 3.3 VOLT VCXO
Description
The MK3711 series of devices include the original
MK3711S, MK3711A, and the new MK3711B and
MK3711D. The MK3711D and MK3711B are drop-in
replacements for the MK3711S and MK3711A devices.
Compared to these earlier devices the MK3711D and
MK3711B offer a wider operating frequency range and
improved power supply noise rejection.
The MK3711 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 MK3711 is
designed primarily for data and clock recovery
applications within end products such as ADSL
modems, set-top box receivers, and telecom systems.
The MK3711D exhibits a moderate VCXO gain of
120ppm/V typical, when used with a high quality
external pullable quartz crystal. The MK3711B offers a
higher VCXO gain of 150ppm/V, similar to the earlier
MK3711A. The higher intrinsic VCXO gain of the
MK3711C 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.
The frequency of the on-chip VCXO is adjusted by an
external control voltage input into pin VIN. Since 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 3V.
