LOW COST 27 MHZ 3.3 VOLT VCXO
Description
The MK3727E 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 MK3727E is
designed primarily for data and clock recovery
applications within end products such as set-top box
receivers.
The MK3727E exhibits a moderate VCXO gain of 120
ppm/V typical, when used with a high quality external
pullable quartz crystal.
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 V.
Features
MK3727E offers 24-36 MHz output frequency range
(output frequency = 2x crystal frequency) and
improved power supply noise rejection
Uses an inexpensive 12 to 18 MHz external crystal
Ideal for set-top box applications using 13.5 MHz
external pullable crystal to generate lock 27 MHz
clock transport video clock
Ideal for ADSL applications using 17.664 MHz
external pullable crystal to generate locked 35.328
MHz clock physical layer clock
On-chip VCXO with guaranteed pull range of ±115
ppm minimum
VCXO input tuning voltage 0 to 3.3 V
Packaged in 8 pin SOIC (150 mil wide)
Available in Pb (lead) free packaging
Exact drop-in replacement for MK3727S
