OSCILLATORS
FIXED FREQUENCY
These surface mount oscillators are available from 1.20 MHz
SMD EF Models, TCXOs, 3.0 or 5.0 Volts
to 40 MHz
MF Electronics EF (SMD) TCXOs are intended to fit the
standard full size DIL layout for a 14 pin oscillator. These
are versatile oscillators with many specification combina-
tions. They may be had within the frequency range of 1.2
MHz to 40 MHz, and are ideal for high volume, low cost
applications.
VOLTAGE CONTROL OF FREQUENCY
±5 ppm or ±10 ppm min is controlled by external voltage
MECHANICAL CONTROL OF FREQUENCY
±3 ppm min
STABILITY
±1 to ±5 ppm
Many choices of stability and temperature are possible,
resulting in the optimum cost-performance tradeoff.
Oscillators may be for 3.3 or 5.0 volts. Mechanical control
is standard, but electronic control may be added, allowing
the frequency to be set to, or track to a reference frequen-
cy.
TEMPERATURE
Four temperature-stability ranges
AGING
Less than 1 ppm per year
INPUT VOLTAGE
3.3 or 5.0 volts availlable
HCMOS output may be chosen to drive logic devices. but
when clipped sine wave is used, the current is less than 3
mA. They are furnished in tape and reel for automated pro-
duction.
