TC-140

Temperature Compensated Crystal Oscillators (TCXO’s) TC-140 (R Series) Description: The TC-140 series offers performance for short-term stability, phase noise, aging and temperature stability normally only associated with Oven Controlled Crystal Oscillators, while consuming typically <20 mA. Features: Stratum 3 option Frequency from 0.5 to 160 MHz “1 ppm Forever” option TTL, HCMOS and Sinewave Over 600,000 units produced Performance Characteristics Parameter Standard Frequencies: Supply Voltage (Vdd): (other options are available upon request) Characteristics 4.096, 10.00, 12.80, 13.00, 16.384, 19.44, 20.00, 20.48 MHz Available from 0.5 MHz to 160 MHz 12.0 Vdc ±5% 5.0 Vdc ±5% Current draw will vary greatly depending on frequency and output type. For this series TCXO typical current draw will be about 20 mA. Please consult the factory about your exact current requirements.
