Temperature Compensated Crystal Oscillators (TCXO’s)
TC-210 (Z5 Series)
Description:
Vectron International has introduced a series of
surface mount, Temperature Compensated Crystal Oscillators
(TCXO’s) available in frequencies from 0.5 to 160 MHz.
Features:
• Stratum 3 option
• Frequency from 0.5 to 160 MHz
• Aging to <3.5 ppm for ten years
• 3.3 Vdc or 5 Vdc operation
• All outputs available (TTL, HCMOS, PECL, Sine)
Performance Characteristics
Standard Frequencies: 10, 12.8, 16.384, 19.44, 20, 38.88, 40, 77.76, 155.52 MHz
Package Size: 29.21 x 25.40 x 10.03 mm (1.15” x 1.00” x 0.395”)
Supply Voltage: 3.3 Vdc +5% or 5 Vdc +5% (other options are available upon request)
Current: Current draw will vary greatly depending on frequency and output type.
Typical current draw will be about 15 mA and depending on output type
may be less than 2 mA. Please consult the factory about your exact
current requirements.
Output Type: HCMOS/ACMOS 0.5 to 160 MHz
10 TTL 0.5 to 160 MHz
Complementary PECL 10 to 160 MHz
0 dBm / 50 ohm 5.0 to 100 MHz
Temperature Stability: B-307 - +0.3 x 10-7 over 0oC to +50°C
B-ST3*- Stratum 3 over 0oC to +50°C
C-ST3*- Stratum 3 over 0oC to +70°C
C-507 - +5.0 x 10-7 over 0oC to +70°C
F-106 - +1.0 x 10-6 over -40oC to +85°C
NOTE: Tighter stabilities and wider temperature ranges are available, please
consult the factory.
*STRATUM 3 per GR-1244-CORE Table 3-1
Total Stability: <+4.6 x 10-6 for all causes and 10 years
Vs Holdover: <+3.7 x 10-7 for all causes and 24 hours
Aging (typical): <3.5 ppm for ten years @ +70°C
Phase Noise (Typical): Offset Phase Noise
10 MHz, + 3.3 Vdc, A-output 100 Hz -115 dBc/Hz
1 kHz -145 dBc/Hz
10 kHz -150 dBc/Hz
100 kHz -155 dBc/Hz
For HCMOS/ACMOS/TTL & PECL outputs with frequencies above
35 MHz a low phase noise PLL multiplier may be used. Please inform the factory
of your phase noise requirements.
Frequency vs. Supply: <+0.1 ppm for a ±5% change in supply voltage
Electrical Frequency Adjust: +5 ppm minimum via external voltage, 0 to Vdd, positive slope
