Description
Zarlink approved TCXO for GR-1244 & GR-253 Stratum 3
applications.
Frequency Parameters
Frequency
20.0MHz
Frequency Stability
±0.28ppm
Ageing
±4.6ppm max after 20 years
Holdover Stability [±(Fmax-Fmin)/2Fo]:
Temperature, –5 to 80°C, inclusive of Supply Voltage: 3.3V
±5% and Ageing, 24 hours: <±0.32ppm
Free-Run Accuracy, incl.
Calibration @25°C, Temperature –5 to 80°C, Supply Voltage
3.3V ±5%, Load 15pF ±5%, Reflow Soldering and Ageing 20
years: <±4.6ppm ref. to Follow
Electrical Parameters
Supply Voltage
3.3V ±5%
Operating Temperature Ranges
-5 to 80°C
Output Details
Output Compatability
Drive Capability
HCMOS
15pF max
Output Control
Tri-State Operation:
Logic ‘1’ (60%VS) to pad 8 enables output
Logic ‘0’ (20%VS) to pad 8 disables output
When at logic ‘0’ the output stage is disabled for all output
options, but the oscillator and compensation circuit are still
active (Current consumption <1mA)
Output Levels
VOL: 10% Vs
VOH: 90% Vs
Noise Parameters
Phase Noise (max):
–85dBc/Hz @ 10Hz
–110dBc/Hz @ 100Hz
–120dBc/Hz @ 1kHz
–135dBc/Hz @ 10kHz
Environmental Parameters
Storage Temperature: -55 to 125°C
Shock: IEC 60068-2-27, Test Ea: 980m/s2 acceleration for
6ms, 3 shocks in each of 3 mutually perpendicular planes
Vibration: IEC 60068-2-6, Test Fc, Procedure B4: 10Hz-60Hz
1.5mm displacement, 60-2000Hz at 98.1m/s2, 30mins in 3
mutually perpendicular planes at 1 oct/min
Solderability: MIL-STD-202, Method 208, Category 3
Manufacturing Details
Resistance to Soldering Heat: 260°C, 60sec max above
220°C
