Sinewave output TCXO 50 Ohms
Wide frequency range 9.6MHz to 360.0MHz
Supply Voltage from 3.0 to 15.0 Volts
Output 50 Ohm load, power <13dBm
Produced as TCXO or VCTCXO with EFC
DESCRIPTION
EM62E series TCXOs are packaged in an industry-standard, 11.4 x
9.6 x 4.7mm SMD 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).
