1 / 3 page  IQXT-317 TCXO Specification ISSUE 1; January 2016 Outline (mm) Pb-Free Reflow 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 ±1.00ppm Frequency Tolerance @ 25°C ±2°C Tolerance Condition 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 Printed on 26 Apr 16 14:49 using Model Data Sheet V1.2550 Page 1 of 3 Sales Office Contact Details: USA: +1.760.318.2824 France: 0800 901 383 UK: +44 (0)1460 270200 Germany: 0800 1808 443 Email: info@iqdfrequencyproducts.com Web: www.iqdfrequencyproducts.com |
