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
•
Industrial temperature range of -40 to +85ºC allows for use in harsh environmental conditions
•
Excellent incrememtal and best-straight-line linearity
•
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:
– xDSL customer premise equipment
– Cable modems
– ATM/SONET/SDH
Description
These thru-hole VCXOs generate a 3.3
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.
