8798_AA's Vectron 05/30/02 3:11 PM Page 58 Temperature Compensated Crystal Oscillators (TCXO’s) TC-400 (14/4 Single DIP Series) Description: Vectron International has introduced a series of Temperature Compensated Crystal Oscillators (TCXO’s) available in frequencies from 2 to 160 MHz. Features: • Industry Standard 14/4 Single DIP package • Frequency from 2 to 160 MHz • 3.3 Vdc or 5 Vdc operation • All outputs Available (TTL, HCMOS, PECL, Sine) Performance Characteristics Parameter Characteristic Frequency: Supply Voltage (Vdd): (other options are available upon request) Current: Output Type: Temperature Stability: Note: Not all stabilities are available with all frequency/output combinations. Please consult the factory. Available from 2.0 MHz to 160 MHz 5.0 Vdc ±5% 3.3 Vdc ±5% Current draw will vary greatly depending on frequency and output type. For this series TCXO typical current draw will be about 15 mA. Please consult the factory about your exact current requirements.
