EM14E - OUTLINES AND DIMENSIONS
DESCRIPTION
EM14E series TCXOs are packaged in an industry-standard, 14 pin
dual-in-line package. The TCXO may be specified to operate at any
supply voltage from 3.0 to 15.0 Volts. Close tolerances from ±1ppm
over -40° to +85°C are available. With true sine wave output, the part
can be produced as either a standard TCXO or a voltage-controlled
TCXO (VCTCXO).
