rakon gowiemperature Compensated Crystal Oscillators Low cost SMD TCXO with voltage control option, using an analogue IC for compensation. Frequencies ranging from 10MHz to 40MHz. aSduct description The IT3200C with voltage control option, employs an analogue IC for the oscillator and temperature compensation. The RSX-8 crystal is surface mounted on top of the ceramic IC carrier. The segregation of the crystal from the oscillator further improves the reliability of the product. Applications • Feature phone • GPS • Wi-Fi • WiMAX/W-LAN • Other 1.0 SPECIFICATION REFERENCES Line Parameter Description 1.4 Rakon part number 2.0 FREQUENCY CHARACTERISTICS Line Parameter Test Condition 2.2 Frequency calibration 2.3 Reflow shift over temperature 2.6 Frequency slope 2.10 Long term stability Offset from nominal frequency measured at 25°C Two consecutive reflows as per attached profile after 1 hour recovery at 25°C The operating temperature over which the frequency stability is measured 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) Minimum of 1 frequency reading every 2°C, over the operating temperature range (Note 1) Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25°C Supply voltage varied ±5% at 25°C ±10% load change Frequency drift over 1 year at 25°C Unit MHz ppm ppm °C ppm ppm/°C ppm ppm ppm ppm Line Parameter Test Condition Nominal supply voltage At maximum supply voltage (Note 2) Unit V mA
