IQD launches "ultra high stability" OCXO
IQD has launched the IQOV-70 series OCXO, designed for use in next generation multimode base station platforms.
Operating at a frequency of 10MHz, the model has a frequency stability of ±3ppb over -10 to +70 degrees C.
Multi-mode base station platforms are based upon TD-LTE technology, fully supporting HSDPA/MBMS/HSUPA/HSPA+ which share the same platform as LTE and accommodating densely populated and suburban areas, rural areas and indoor locations.
The new design is built around a stress compensated-cut crystal, designed and manufactured in-house at IQD FOQ.
Output capability can be either HCMOS or LV-TTL with supply voltage options of 5 or 12V.
Electrical frequency adjustment of ±0.4ppm min allows for ageing over time. Phase noise performance of < -155dBc/Hz at an offset of 10kHz is particularly important bearing in mind the application and its need for high capacity data transfer.
Frequency ageing is limited to ±0.05ppm maximum over a period of 1 year.
As standard, the design is housed in an industry standard IEC C008 5-pin Euro package with a height of only 13mm max but surface mount packages are also available.
