Description
An ultra stable, surface-mount Temperature Compensated
Crystal Oscillator (TCXO) delivering exceptional phase noise
and jitter performance and enhanced frequency versus
temperature stability.
FEATURES:
RMS phase jitter down to 0.13ps.
Phase noise < ‐160dBc/Hz noise floor.
Voltage Control and T‐sense options available.
APPLICATIONS:
Positioning
Test & Measurement
Telecommunications
Hi‐Rel / Defence
Standard Frequencies: 10.0MHz, 12.80MHz, 16.3840MHz,
19.20MHz, 19.440MHz, 20.0MHz, 25.0MHz, 26.0MHz,
30.720MHz, 38.880MHz and 40.0MHz.
Frequency Parameters
Frequency
1.25MHz to 52.0MHz
Frequency Tolerance
±1.00ppm
Tolerance Condition
@ 25°C ±1°C
Frequency Stability
±0.05ppm to ±2.50ppm
Frequency Stability: Measurement referenced to
(Fmax+Fmin)/2.
Note: The best available stability depends on the nominal
frequency and selected operating temperature range.
Ageing:
F≤26.0MHz: ±1ppm max/yr, ±3ppm max over 10yrs
F>26.0MHz: ±2ppm max/yr, ±5ppm max over 10yrs
Root Allan Variance (F=20.0MHz @ 25°C, tau=1sec): 5xE-11
typ
Acceleration Sensitivity (gamma vector of all 3 axes from 30 to
1500Hz): Typically 2ppb/G max
Supply Voltage Variation (±5% change @ 25°C ref to
frequency @ nominal Vs): ±25ppb typ
Load Variation:
HCMOS & ACMOS (±5pF change @ 25°C ref to frequency @
nominal load): ±50ppb typ
Sine & Clipped Sine (±10% change @ 25°C ref to frequency
@ nominal load): ±50ppb typ
Reflow Variation (after 1hr recovery @ 25°C): ±0.5ppm max
Electrical Parameters
Supply Voltage Range: 2.5V to 5.7V
(Standard Voltages are 3.0, 3.3 & 5.0V)
Supply Current:
HCMOS: 4mA typ
ACMOS: 8mA typ
