FIXED FREQUENCY
These surface mount oscillators are available in eight standard
SMD ER Models, TCXOs, 3.0 or 5.0 Volts
frequencies. Other frequencies on special order
MF Electronics ER (SMD) TCXOs are -30 to +75 ºC oscilla-
tors which offer 4 choices of supply voltage and frequency
control. These are available at eight standard frequencies
from 12.0 to 19.68 MHz. They are ideal for high volume, low
cost applications.
VOLTAGE CONTROL OF FREQUENCY
±4 ppm min is user-controlled by external voltage
MECHANICAL CONTROL OF FREQUENCY
±4 ppm min via externally accessible trimmer
STABILITY
±2.5 ppm
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 frequency.
TEMPERATURE
-30 to +75ºC
AGING
Less than 1 ppm year
Output is a clipped sine wave, and the current is less than 2
mA. Phase noise is within -125 dBc/Hz at 1 KHz offset.
These oscillators are recommended for wireless, PCS, GSM
and PC applications. They are furnished in tape and reel for
automated production.
