TCXO Specification
IQXT-317
ISSUE 1; January 2016
Outline (mm)
Description
A high performance, surface-mount Temperature
Compensated Crystal Oscillator (TCXO) offering excellent
phase noise, frequency stability and VC tilt compensation. The
IQXT-317 employs an analogue IC for the oscillator and
temperature compensation.
FEATURES:
Excellent Phase Noise and Frequency Stability performance.
Frequency Slope and Perturbation specifications can be
customized.
APPLICATIONS:
Communications, Base Station, Femtocell,
DSL/ADSL, LTE, SONET/SDH, WiMAX/WiBro, WLAN,
IP Timing, Precision GPS.
Frequency Parameters
5.0MHz to 52.0MHz
Frequency
±1.00ppm
Frequency Tolerance
Tolerance Condition
@ 25°C ±2°C
Frequency Stability (referenced to (Fmax+Fmin)/2,
temperature ramp ≤1°C/min and VC=2.5V): ±0.1ppm to
3.0ppm
Ageing (@ 25°C): ±1ppm max over 1yr
Frequency Slope (minimum of one frequency reading every
2°C over the operating temperature range, temperature ramp
≤1°C/min and VC=2.5V): 0.1ppm/°C max
Static Temperature Hysteresis (frequency change after
reciprocal temperature ramped over the operating range frequency measured before and after @ 25°C): 0.4ppm max
Supply Voltage Variation (±5% change @ 25°C): ±0.1ppm max
Load Variation (±10% change @ 25°C and load as stated in
Output Details section): ±0.2ppm max
Reflow Variation (after two consecutive reflows as per profile
shown and 1hr recovery @ 25°C): ±1ppm max
Note: Parts should be shielded from drafts causing unexpected
thermal gradients. Temperature changes due to ambient air
currents can lead to short term frequency drift.

Output Details
Output Compatability
HCMOS/Clipped Sine
HCMOS Output Waveform:
Output Voltage Level Low (VoL): 10%Vs max
Output Voltage Level High (VoH): 90%Vs min
Rise and Fall Times (measured @ 10pF): 5ns max
Duty Cycle (measured @ 50% level): 40/60% max
Output Load Capability: 10pF
Settling Time (time taken for frequency to reach specified
Frequency Tolerance): 10ms max
Note: Assumes no phase noise filtering - if low phase noise is
required the Settling Time will be extended.

1ms max
Settling Time (time taken for frequency to reach specified
Frequency Tolerance): 10ms max
Note: Assumes no phase noise filtering - if low phase noise is
required the Settling Time will be extended.
Noise Parameters
Phase Noise (typical for a 10MHz HCMOS oscillator @ 25°C):
-75dBc/Hz @ 1Hz
-98dBc/Hz @ 10Hz
-127dBc/Hz @ 100Hz
-147dBc/Hz @ 1kHz

-155dBc/Hz @ 100kHz
-157dBc/Hz @ 1MHz
Environmental Parameters
Storage Temperature Range: -40 to 85°C
Mechanical Shock: IEC 60068-2-27: Half sine-wave
acceleration of 100G peak amplitude for 6ms duration, 3 times
in 3 mutually perpendicular planes.
