AUSTIN, TX – Abracon, LLC (Abracon), an industry leader in providing frequency control & timing, RF & antenna, and inductor & connectivity component solutions, announces the release of a new application note titled “ABS05 Tuning Fork Crystal: 1.6 x 1.0 x 0.5 mm device optimized for energy-saving MCUs.”

Please read the excerpt below:

Over the past two years, supply chain challenges have significantly complicated high-volume availability of the industry-standard 3.2 x 1.5 mm and 2.0 x 1.2 mm tuning fork quartz crystals with lower plating loads. Abracon took this challenge into consideration and developed the 4.0pF plated version of its miniature ABS05 series. 

Abracon’s ABS07 family of 3.2 x 15 x 0.9 mm tuning fork quartz crystals have been the workhouse solution utilized in a broad breadth of applications from industrial and medical electronics to consumer IoT gadgets. As the utilization of next-generation MCUs has taken hold, the need for a lower plating load (down to 4.0pF) version of the ABS07 gained momentum.

Simultaneously, the industry’s continuous trend to miniaturize end-product designs has given way to demand for 2.0 x 1.2 x 0.6 mm tuning fork quartz crystals, which is represented by Abracon’s ABS06 family products. In particular, Abracon’s ABS06-107 at 4.0pF plating load has drawn popular interest. It presents a unique combination of lower plating load coupled with optimized equivalent series resistance (ESR) performance, making it ideally suited for energy-saving gorilla chips.

However, the 1.6 x 1.0 x 0.5 mm ABS05 family can easily replace the larger-sized ABS06 and ABS07 families in current designs without sacrificing performance requirements or adding extra design pressure. It can also enable further reduction of consumed surface area in newer designs.

Employing state-of-the-art tuning techniques, the ABS05 devices are now available with ±20 ppm and ±25 ppm set-tolerance into an effective oscillator-loop load capacitance of 4.0pF. Further, the ESR is optimized to maintain a threshold of 90 kΩ maximum, enabling robust operation when mating with the latest energy-saving MCUs and other gorilla chipsets.

Furthermore, due to the recent supply chain issues, designers might want to consider a comprehensive, all-encompassing land pattern in their designs. This approach provides design flexibility by enabling the use of either the ABS07, the ABS06 or the ABS05 package within the same layout to satisfy design requirements.
