GUARANTEED CAPTURE RANGE/ABSOLUTE PULL RANGE
Guaranteed Capture Range (GCR) and Absolute Pull Range (APR) are terms often used interchangeably.
MF's Guaranteed Capture Range (GCR) is defined as the minimum guaranteed frequency deviation or
"pull" (in ppm) around the nominal frequency, with all effects of temperature, variations in VDD and load
taken into account. This amount of absolute frequency deviation is available under all operating conditions
for modulation or capturing other signals. No additional frequency capture allowances are necessary.
FEATURES

•
Start-up time is less than 5ms
•
Each unit is ATE-tested to guarantee full compliance with all electrical specifications
TYPICAL APPLICATIONS
•
Phase locked loops and data acquisition projects, including:

Description
These SMD VCXOs generate a 5 volt
HCMOS/TTL frequency output which is
controlled ("pulled") by an input voltage.
MF Electronics' VCXO specification
defines not only the end-point frequency/
voltage parameters, but also the center
voltage at which the nominal frequency
is acheived.

FREQUENCY STABILITY
Frequency stability vs. Temperature (0 to 70°C) is typically better than
±20 ppm. Since the deviation of each oscillator is tested and guaranteed
over the whole operating temperature range, it is not necessary to make
additional capture allowances. All oscillators will capture frequencies with
the full minimum values of the deviation under all conditions.
QUALITY
Each VCXO is computer-tested at three temperatures to guarantee
full compliance to the specification.
