(TCXO’s) available in frequencies from 1 to 77.76 MHz.
Features:
• Low profile surface mount package
• Frequency from 1 to 77.76 MHz
• 3.3 Vdc or 5 Vdc operation
• TTL & HCMOS outputs
Performance Characteristics
Standard Frequencies: 10, 12.8, 13, 16.384, 19.44, 20, 20.48, 27 MHz
Available from 1 MHz to 77.76 MHz
Package Size: 22.86 x 17.78 x 3.81 mm (0.90” x 0.70” x 0.15”)
Supply Voltage (Vdd): 3.3 Vdc ±5%, 5 Vdc ±5% (other options are available upon request)
Current: Current draw will vary greatly depending on frequency and output type.
For this series TCXO typical current draw will be about 10 mA. Please
consult the factory about your exact current requirements.
