Abracon Announces 10ppb Stability OCXOs for Precision Holdover Applications

2021-08-09 | 반환

Austin, Texas – Abracon, LLC (Abracon), The Heartbeat of the IoT®, a leading global manufacturer of frequency control, timing, synchronization, RF, connectivity and power solutions, expanded its offering of SMD oven-controlled crystal oscillators (OCXO), with the AOC2012, AOC1409 and AOC2522A/AOC2522B.

These OCXO solutions employ a precision SC-cut high “Q” quartz crystal resonator design, coupled with precision temperature monitoring and control circuitry. This combination enables Abracon to meet Stratum 3 and 3E requirements with this family of OCXOs.

This family of OCXOs works ideally for 5G or GPS applications requiring high frequency stability with low phase noise and precision holdover performances, such as base stations, small cell platforms, internet data centers, and satellite and aerospace communications.

Precision stability over temperature combined with an ultra-low ±1ppb daily aging enables a ±15ppb, 24-hour holdover accuracy, depending on system conditions. Holdover extends a system’s useful operating period in the event it loses its reference clock, which is an important consideration when designing RF, networking, telecommunications, GPS and reference-timing applications. Additionally, tight short-term stability improves acquisition time in low-bandwidth phase-locked loops and overall accuracy in GPS applications.

The AOC1409 supports the 20MHz frequency in a small 14.9 x 9.7 x 7.0 (6-pin) package. The AOC2012 has a 20.32 x 12.70 x 11.00mm SMD (4-pin) package and a -20°C to +70°C operating temperature range. The AOC2522 series features ±750ppb long-term aging and is available in a 25.4 x 22 x 12.7mm (5-pad) package size. The AOC1409 and AOC2522 offer a -40°C to +85°C operating temperature range.

This family of OCXOs are now available through Abracon’s global distribution network.
