EM53S - OUTLINES AND DIMENSIONS
DESCRIPTION
EM53 series TCXOs are ceramic SMD TCXOs packaged in an industrystandard, micro-miniature 5 x 3.2mm package. This TCXO can be run
from a supply voltage of 2.3 to 5.5 Volts. Close tolerances from
±1ppm over -30° to +75°C are available. The part can be produced
as either a standard TCXO or a voltage-controlled TCXO (VCTCXO).

voltages. (Contact technical sales if
+2.5±2.0 Volts is required.)
Frequency Deviation: ±6.0 ppm min.
Slope Polarity:
Positive (increase of control voltage increases
output frequency.)
Input Impedance:
1.0M min.
Modulation Bandwidth: 3.0kHz min. measured at -3dB
Linearity:
10% max.
* Stability over temperature is measured from this initial frequency.
