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
Frequency: Available from 2.0 MHz to 160 MHz
Supply Voltage (Vdd): 5.0 Vdc ±5%
(other options are available upon request) 3.3 Vdc ±5%
Current: 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.
Output Type: HCMOS/ACMOS 2.0 to 160 MHz
10 TTL 2.0 to 160 MHz
PECL 10.0 to 160 MHz
0 dBm/50 ohm 16.384 to 77.76 MHz
Temperature Stability: B-106 - ±1.0 x 10-6 over 0°C to +50°C
Note: Not all stabilities are available B-156 - ±1.5 x 10-6 over 0°C to +50°C
with all frequency/output combinations. C-106 - ±1.0 x 10-6 over 0°C to +70°C
Please consult the factory. C-156 - ±1.5 x 10-6 over 0°C to +70°C
D-156 - ±1.5 x 10-6 over -20°C to +70°C
D-206 - ±2.0 x 10-6 over -20°C to +70°C
F-156 - ±1.5 x 10-6 over -40°C to +85°C
F-256 - ±2.5 x 10-6 over -40°C to +85°C
NOTE: Tighter stabilities and wider temperature ranges are available, please
consult the factory.
Aging (typical): <10 ppm for ten years @ +70°C
Frequency vs. Supply: <±0.2 ppm for a ±5% change in supply voltage
Pin 1 Options: A= Electrical Frequency Adjust -- ±10 ppm minimum via external
voltage, 0 to Vdd - positive slope
B= Tri-state -- HCMOS/TTL
Enable/Disable -- PECL
C= No connect -- Initial Accuracy ±2.5 ppm @ +25°C
Package Size: 20.32 x 12.70 x 10.287 mm (0.80” x 0.50” x 0.405”)
