The launch of the ABMxW and ABSxW series results in the industry's most comprehensive family of crystals, addressing the leap to lower power. Oscillators within next generation energy saving MCUs and chipsets are failing to drive traditional crystals with higher CL and ESR. Reducing the load capacitance to a new industry level of 4pF for MHz crystals and 3pF for tuning fork crystals, while simultaneously providing guaranteed low ESR, enables operation with design margin for many chipsets starved of gain and reduced transconductance (gm). These optimized crystals ensure the crystal oscillator design retains enough margin to operate over temperature and across all process and voltage corners.

"gm (amplifier transconductance) is a critical parameter that determines your oscillator loop's design margin," said Syed Raza, VP of Engineering for Abracon. "To minimize total power consumption, techniques employed in the latest SoC/µC/µP/RFIC/FPGA's reduce the value of gm within the oscillator loop. To maintain the original design margin as gm drops, crystals must meet a lower gm_critical metric. Abracon's performance optimized IoT crystals achieve exactly that, by simultaneously reducing plating load, ESR, and electrode capacitance of these devices. After all, lower power consumption should not be achieved at the expense of long term reliability or design risk."
"The IoT, wearables, and portable markets demand the power savings achieved with next generation ICs. Those ICs directly benefit from this industry leading series of low CL crystals," commented Juan Conchas, Director of Marketing for Abracon.
The ABMxW and ABSxW series are offered in a variety of package, stability and tolerance options down to +/-10ppm. A comprehensive offering overall operating temperatures up to -40°C to 125°C makes these crystals suitable for both consumer and industrial designs.
