IQD’s new IQXT-60 series Temperature Compensated Crystal Oscillator (TCXO) offers excellent phase noise performance in a miniature, low height package. With typical phase noise figures of -63dBc/Hz at 10Hz and -161dBc/Hz at 100kHz coupled with a low current consumption of around 5.0mA, the new model is a very versatile high performance oscillator. Phase noise performance is increasingly critical for applications delivering fast data transfer such as GPS, GSM, WCDMA and WiMAX as well as a very wide range of portable applications.
Housed in a miniature 3.2 x 2.5mm ceramic package measuring only 1.0mm high, the new model is available at any frequency from 4.0MHz to 54.0MHz; this is exceptionally wide for a TCXO and obviates the need for external dividers or multipliers in many applications. The frequency stability of ±2.5ppm over the operating temperature range of –30 to +75 degrees C and frequency tolerance of ±0.5ppm matches existing industry standards. The IQXT-60 series has a HCMOS output capable of driving 15pF whilst operating from a standard 3.3, 2.8 or 2.5V power supply.
