TCXO Specification

IQXT-314

ISSUE 1; January 2016

Description

Outline (mm)

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.

Example Phase Noise @ 19.20MHz

Frequency Parameters

Frequency

1.25MHz to 52.0MHz

±1.00ppm

Frequency Tolerance

Tolerance Condition

Frequency Stability

@ 25°C ±1°C

±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:

Example Phase Noise @ 51.84MHz

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

Sine: 8mA typ

Clipped Sine: 2mA typ

Frequency Adjustment
