PECL 10KH –
Thru-Hole VCXOs, 5V
These thru-hole VCXOs are designed for
compatibility with digital and communications
systems based on the PECL 10KH logic family.
They provide fast rise times, wide frequency
range, and good waveform symmetry at
economical cost.
Users have a choice of a dozen off-the-shelf
models. Diverse combinations of pull, control
voltage and center frequency deviation are
available, accommodating a wide variety of
filtering and driving circuitry. These VCXOs are
hermetically sealed in full size (M) DIL packages
with four pins. MF Electronics’ PECL VCXOs
and are available at frequencies from 12.5 to
175 MHz. Frequency stability choices extend
from ±25 ppm, to 50 ppm.
All VCXOs are single-ended and tested and
guaranteed over the full operating temperature.
For superior performance, including comple-
mentary outputs, see our series 2900s VCXOs
based on ECLPS logic.
These thru-hole PECL VCXOs generate a PECL
frequency output which is controlled by an input
voltage. The end-point frequency/voltage parameters
are defined, as is the center frequency.
CAPTURE RANGE
The Frequency-Capture range is equal to the (Center-Frequency ± the
Frequency Deviation), because every MF VCXO is ATE-tested to meet the
Frequency-Deviation over the temperature range.
Frequency Capture
specification includes all effects of temperature and supply voltage.
It is not necessary to make additional capture allowances.
FEATURES
•
Frequency from 1 MHz to 175 MHz
•
Capture-range is fully defined, under all conditions
•

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 allowance. 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.
