The MF PECL oscillators are available in a variety of common config-
urations. Models are full size or half size, in 10 KH logic, with and
without complementary outputs. Frequency tolerances from 100 ppm
to 20 ppm include all effects of voltage, load and aging.
Description
MF Electronics’ high speed clock
oscillators for digital and communications
applications are based on 5V PECL logic
and are available in full size (M) and half
size (H) thru-hole packages. Designs in
10KH logic develop 10 MHz to 210 MHz
output, and are available with 45/55
symmetry. They can be optionally provid-
ed with dual complementary output.
Frequency stability extends from the
high end at ±20 ppm to ±100 ppm.
For superior performance, see our
model 2900s using ECLPS logic.
FEATURES
• DIL – full size or half size
• Single or dual complementary outputs
• H1900 and M1900 have Enable/Disable, reducing noise of unwanted frequency
• Start up time less than 5 ms
• Stability options from .01% (100 ppm) to .002% (20 ppm)
• Guaranteed start-up with ramping DC Supply
• Terminating resistor may be internal – consult factory

ENABLE/DISABLE
The M1900 and H1900 have Enable-Disable feature, which allows several
oscillators to be wire-OR'd, so that one frequency of several may be
selected. If Pin1. is “0”, the output is normal, However, when Pin1. is “1”,
the oscillator shuts-down, and the output goes to logic “0”'. The logic “0”
may be wire-OR'd.

AUTOMATED TESTING (ATE)
+5V
Automated testing can effectively be performed using the M1900, since
this model may be turned-off and “0”'d, allowing an ECL test frequency
to be inserted on the output node.
