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:

over 0C to +50C
Note: Not all stabilities are available
B-156 - 1.5 x 10
-6
over 0C to +50C
with all frequency/output combinations.
C-106 - 1.0 x 10
-6
over 0C to +70C
Please consult the factory.

F-256 - 2.5 x 10
-6
over -40C to +85C
NOTE: Tighter stabilities and wider temperature ranges are available, please
consult the factory.
Aging (typical):
<10 ppm for ten years @ +70C
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 @ +25C
Package Size:
20.32 x 12.70 x 10.287 mm (0.80" x 0.50" x 0.405")
