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
Frequency
5.0MHz to 52.0MHz
Frequency Tolerance
±1.00ppm
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.
Electrical Parameters
Supply Voltage Range: 2.8V to 5.5V
Supply Current (@ TA=25°C, Vs max and load as stated in
Output Details section): 2.9mA max
Frequency Adjustment
Pulling
±6ppm to ±30ppm
Control Voltage
2.5V ±2.0V
Input Impedence
100kΩ min
Linearity (deviation from straight line curve fit): 10% max
Note: VC of 4.5V is only applicable when a Vs of 5.0V is
applied.
Operating Temperature Ranges
-40 to 85°C
