Description
Commercial: 0º to 70ºC
15 MHz to 175 MHz
These ECLPS VCXOs feature super-low
jitter of 20 ps peak-to-peak — within the
bandwidth of 12 KHz to 20 MHz the jitter
will not exceed 1 ps RMS. They are
based on the same logic as our M2910s
fixed frequency oscillators, and therefore
exhibit identical waveform characteristics.
These thru-hole VCXOs are designed for
compatibility with digital and communica-
tions systems based on the ECLPS
These VCXOs provide complementary PECL outputs thru 175 MHz
with extremely fast rise and fall times. Each oscillator is computer
tuned and computer tested to guarantee stability and frequency
pull at 0º, 25º and 70ºC. All oscillators will capture the rated pull
at all operating temperatures.
FEATURES
family of high speed PECL logic.
• Jitter less than 1 ps RMS from 12 KHz to 20 MHz
• Super low jitter of 20 ps peak to peak maximum limits loss of data packets in digital data recovery
• Will drive standard interface chips in complementary PECL.
• Duty Cycle is typically 48/52
Users have a choice of the three most
widely used combinations of pull, control
voltage and center frequency deviation.
The oscillators are available at frequencies
from 15 to 175 MHz. Standard frequency
stability is ±20 ppm.
• Three frequency deviation choices
• Output is PECL with typical rise and fall times of 225 ps
• Exceptional linearity with Deviation Sensitivity Ratio not exceeding 2.0
• Package is choice of double DIL, standard DIL with 7 pins (M1)
All models have dual complementary
outputs. All feature 250 ps typical rise/fall
times and provide superior jitter. Their low
output impedance and dual complemen-
tary outputs preserve waveform symmetry
when sending the timing waveforms over
appreciable distance. Output symmetry of
45/55 is standard.
TYPICAL APPLICATIONS
• Used in Sonet ST33 interface for generation of the transmitter data clock
SPECIAL APPLICATION NOTES
All outputs must be loaded with 270 ohms to ground, or 50 ohms to +3V
•
Outputs will drive all PECL families when they are operated in PECL configurations
•

(24.89)
Designed originally for advanced SONET
applications, their combination of advanced
characteristics provides special appeal to
designers of highly evolved phase-locked-
loop circuits. They provide tight control of
the voltage-to-frequency (∆F/∆V) transfer
function and feature jitter specifications of
less than 20 pico-seconds peak-to-peak.
Typical RMS jitter is 2.048 ps RMS.

Fig. 1: 155.52 MHz PECL oscillator,
showing steep rise and fall times and
excellent duty cycle. Levels have 900 mv
difference between “1” and “0”.
Fig. 2: M2912-77.76 MHz oscillator with
expansion of transition at 3.7 volts. Jitter is
shown by the histogram of the distribution
of the waveform at 3.7 volts. The distribu-
tion is unimodal, with peak-to-peak jitter
of 16 ps peak-to-peak, and 2.27 ps RMS.
HOW TO ORDER
For Part Number, put package type before model number,
and add frequency in MHz, for example:
M 2 9 1 2- 7 7 .7 6 M
“M” is full size DIL
“W” is double wide DIL is model
type
“2912”
