FIXED FREQUENCY
These surface mount oscillators are available in thirteen stan-
dard frequencies
SMD EB Models, TCXOs, 3.0 Volts
VOLTAGE CONTROL OF FREQUENCY
±5 ppm min is user-controlled by external voltage
MF Electronics EB (SMD) TCXOs are ideal for high volume,
low cost applications. With miniature 7 x 5 x 2 mm size,
these oscillators use tiny precise crystals operating at stan-
dard frequencies from 10 to 20 MHz. Thirteen common fre-
quencies are available. They have electronic frequency con-
trol of ±5ppm, allowing the frequency to be set to, or to
track a reference frequency.
STABILITY
±2.0 or ±2.5 ppm
TEMPERATURE
-30 to +80ºC or -20 to +70ºC
AGING
Less than 1 ppm per year
Operating at 3.0 volts and with current not exceeding 2
mA, they are ideal for battery operated equipment. This
group of models include the 10 MHz and 20 MHz frequen-
cies which may be used for counting and timing applica-
tions.
INPUT VOLTAGE
3.0 volts is standard. 5.0 volts may be had on special order

They are furnished in tape and reel, for automated produc-
tion and come with large gold or solder plated pads. Side-
castellations accept solder flow, and facilitate automated
solder joint inspection.

(1) Number in date code is year. In example, “1” is 2001.
(2) Letter in date code is one two-week period. Year is divided
into 26 two-week intervals. Each two-week interval is repre-
sented by one letter of the alphabet, in sequence.
