New low phase noise TCXO from IQD

IQD’s new IQXT-60 series Temperature Compensated Crystal Oscillator (TCXO) is able to offer improved 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 provides greater versatility.

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 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.
