TCXO ideal for GPS weak signal detection

11 July 2007 Electronics Technology

With a frequency stability of ±0,5 ppm over a wide temperature range of -30 to 85°C, the IT2200A TCXO (temperature controlled crystal oscillator) from Rakon offers excellent performance in the smallest footprint currently available at 2,5 x 2,0 mm. With a low power requirement, drawing just 1,5 mA from a 3,7 V supply, the IT2200A is ideal for use in portable devices.

Available with a Clipped Sinewave output and in frequencies ranging between 10 and 40 Hz, this SMD RoHS-compliant TCXO uses an analogue IC for the oscillator and temperature compensation circuitry. The high stability enables extended coherent integration periods to increase sensitivity for weak signal applications. High stability can greatly reduce acquisition times, allowing the GPS system to consume less power.

With its low power consumption, high stability and small size, the IT2200A is ideal for weak signal GPS applications including mobile phone emergency location, location based services and personal security.
