The MF ECL oscillators are available in a variety of common configu-
rations. Models are full size in 10 KH logic, with and without comple-
mentary outputs. Frequencies are from 10 MHz to 210 MHz. Frequency
tolerances from 100 ppm to 25 ppm include all effects of voltage,
load and aging.
FEATURES
• DIL full size
• Single or dual complementary outputs
• Start up time less than 5 ms.
Description
MF Electronics’ high speed clock oscillators
for digital and communications applica-
tions are based on 5V 10KH ECL logic
and are available in full size (M) DIL thru-
hole/gull wing packages. Designs in ECL
10KH logic develop 10 MHz to 210 MHz
output, and are available with 45/55
symmetry. They can be provided with
dual complementary output at frequen-
cies through 210 MHz. Frequency stabili-
ty extends from the high end at ±25 ppm
to ±100 ppm. For superior performance,
see our model 2900s using ECLPS logic.
• Stability options from .01% (100 ppm) to .0025% (25 ppm)
• Guaranteed start-up with ramping DC Supply
• Terminating resistor may be internal – consult factory
