Description
The IQXT-272 employs an analogue ASIC for the oscillator
and a high order temperature compensation circuit in a 2.0 x
1.6mm size package. The device can be placed in power down
mode through a single input pin. During standard operation,
power consumption is minimised by operating down to a
supply voltage of 1.8V. The IQXT-272's high stability, low
power consumption, small footprint and powerful
compensation method makes it a TCXO ideally suited for
demanding GPS mobile applications.
Applications:
Communications
Consumer
GPS
Features:
Excellent phase noise performance
Low start up drift rate
Height less than 0.8mm
Operates at 1.8V supply
Power Down Mode
Temperature sensor
Standard temperature stability of ±0.5ppm over wide
temperature ranges
Frequency Parameters
Frequency
13.0MHz to 52.0MHz
Frequency Tolerance
±2.00ppm
Frequency Stability
±0.50ppm to ±2.00ppm
Frequency calibration + reflow: Offset from the nominal
frequency measured at 25˚C ±2˚C. Two consecutive reflows as
per profile after 2 hours relaxation at 25°C
Frequency stability over temperature: referenced to the
midpoint between minimum and maximum frequency value
over the specified temperature range. Control voltage set to
midpoint of control voltage (Note 1)
Frequency slope, minimum of 1 frequency reading every 2°C,
over the operating temperature range (Note 1): 0.05 to
1ppm/°C
Static temperature hysteresis: frequency change after
reciprocal temperature ramped over the operating range.
Frequency measured before and after at 25°C: ±0.6ppm max
Supply voltage variation (±5% change at 25°C): ±0.1ppm max
Load variation (±10% change, note 2): ±0.2ppm max
Long term stability, frequency drift over 1 year at 25°C: ±1ppm
max
