IQD launches a new GNSS-disciplined crystal oscillator.

IQD has launched a new series of GNSS-disciplined oven controlled crystal oscillators (OCXOs), the IQCM-112 series.

The new design incorporates an internal GNSS receiver with a 1PPS output, which is compatible with an external GPS, GLONASS, BeiDou and Galileo source. It is housed in a 14-pin 60-millimeter-square package.

The design incorporates an internal adaptive algorithm that enables the module to “learn” the parameters of the GNSS signal after a period of three days of lock, so that the holdover function can start in the event of signal failure.

A built-in internal alarm indicates lock failure and subsequent restoration of signal. The unit incorporates a serial connection for more detailed interrogation of the device’s performance.
