New OCXO series in miniature form-factor provides high stability

IQD, part of the Würth Elektronik eiSos Group, announced the release of a new miniature OCXO in its range of enhanced performance oscillators: IQOV-116 at electronica 2024. This extended operating temperature range of OCXOs offers high stability in an extremely small 7.5mm x 5.5mm surface mount package. It is the smallest SMD OCXO in the IQD range and brings OCXO performance down to the size of standard 7mm x 5mm clock oscillators.

The series has an HCMOS output and boasts a range of features, including high stability of ±20ppb over a wide temperature range of -40C to 95C, low phase noise (-150dBc/Hz typ @ 1KHz), 3.3V supply voltage, and low power consumption at 230mA steady state. It is supplied in three standard frequencies: 10MHz, 19.2MHz, and 20MHz, with others available upon request.

This small device is excellent for a range of applications, including wireless communication, small cells, further communication infrastructure, frequency reference, and measurement systems.

The series can be packaged on tape and reel, which is ideal for assembly using standard ‘pick-n-place’ equipment.

An OCXO offers frequency stabilities vastly tighter than those seen in standard clock oscillators and even from TCXOs. Due to temperature shift, the frequency drift of the quartz crystal is lowered to a minimum by heating the crystal in an oven and holding the temperature of the quartz at a fixed point.
