Choose the right quartz crystal for your energy saving MCU with THIS simple test

Next generation MCUs and RF chipsets, commonly used in IoT, wearable, and battery powered applications, have presented a problem frequently ignored by many designers across all industries. Lower power consumption requires next generation crystals to optimize for a weaker gain and drive from the Pierce analyzer. The ability to sustain oscillation for a given quartz crystal oscillator design depends heavily on the crystal’s motional parameters, board parasitics, and oscillator circuit characteristics. Yet, as MCUs are upgraded to lower power models, their crystal counterparts have stayed the same. The Pierce oscillator circuit, a closed loop system most commonly integrated into low power ICs, sustains oscillation at an operating point, depending on the crystal plating capacitance (CL), crystal equivalent series resistance (ESR), and oscillator amplifier’s gain and phase response associated with the oscillator’s transconductance (gm). But, how do you know if your crystal’s parameters match your system?

Abracon’s Pierce analyzer system (PAS) was designed by our engineers to help you make the right choice for your industry leading designs. The PAS test validates quartz crystal performance in-circuit and simultaneously measures the crystal, crystal oscillator, and printed circuit board parasitics. Testing in-system accounts for all variables and enables ideal matching of crystal parameters to the board and oscillator in the MCU or RF chipset. This is especially critical for applications using next generation, energy saving technologies requiring optimal gm factors.

Lower CL and lower ESR increase operating gain margin of the loop, ensuring sustained oscillations across all variables including variation in bias, loading, temperature, and over time. Gm_critical is the critical transconductance value that a crystal must achieve in order to remain in the safe zone of loop operation. Crystals that do not meet gm_critical are not well matched to the Pierce oscillator and may cause long term reliability issues associated with startup. Since lower power consumption decreases gm and gm_crictical for a given Pierce oscillator, energy saving designs deployed in IoT and wearables applications are the most at risk of failure. Conducting a PAS test reduces risk and improves the reliability of your system.

“Semiconductor technology strives to wring all the power consumption out of the latest generation of MCUs and RF chipsets,” commented Syed Raza, VP of Engineering with Abracon “the on-chip Pierce oscillator is starved of much needed gain negatively impacting the gm_critical metric. The PAS test is the surest way to diagnose preventable problems.”

“As The Heartbeat of the IoT™, we strive to provide customers with as many tools and services as possible that will take their designs to the next low power plateau. The PAS test service enables validation of a critical subsystem in the design given that nothing will operate if the oscillator fails to run.” commented Juan Conchas, Director of Marketing with Abracon.

The service provides a comprehensive report outlining the functional parameters of the oscillator circuit and recommends changes when necessary. This service is conducted by Abracon and can be ordered through any franchised distributor, with multiple turn-around times from 2-weeks to 4-weeks.

Guaranteed Ultra-Low Jitter 5x7mm XO’s Reduce Design Time in High Bandwidth Applications

150fs RMS max jitter for 156.25MHz output

Austin, TX (December 14, 2016)- Abracon Holdings LLC. (Abracon), a leading global manufacturer of passive & electromechanical timing, synchronization, power, connectivity and RF components has released the ASG-ULJ family of oscillators featuring guaranteed ultra-low phase jitter of 100fs RMS and guaranteed maximum phase jitter of 150fs RMS for 156.25MHz output. Specifying maximum phase jitter removes uncertainty from end system hardware design, reduces clock tree troubleshooting time and speeds time to market in high data rate applications such as 10/40/100/400Gb Ethernet, 5G wireless infrastructure and 25Gbps to 56Gbps chip-to-chip or board-to-board interfaces used by FPGAs and advanced processors.

High performance oscillators targeting clocking applications that drive high bandwidth requirements are ideal for servers, PCI Express accelerator add-on cards, wireless backhaul, base stations, switches, routers, automated test equipment and MRI equipment. The explosive need for higher bandwidth requirements are typical within data centers, telecommunications infrastructure, test equipment and high end medical imaging.

“As part of our strategy to constantly deliver value to our customers, this family of leading performance oscillators directly targets the noise requirements of end equipment that supports the explosive growth of wireless and cloud bandwidth requirements. The ASG-ULJ product family is intended to bring advanced yet accessible clocking technology to these applications,” said Abracon Chief Operations Officer Mike Calabria.

The product family supports industry standard 6-pin 5x7mm footprint with LVPECL, LVDS or LVCMOS output format type. Featuring operation from 3.3V or 2.5V with supply current consumption below 40mA for LVCMOS, these high performance XOs consume no more power than standard performing devices. Operation from -40C to +85C with +/-50PPM total stability including aging is standard.

“We have seen first-hand how engineers grapple with the challenges of designing higher bandwidth into their end equipment. Oscillators with ultra-low jitter performance that are guaranteed to conserve their jitter budget reduce design time off the clocking solution and allow designers to focus on taking their core technology to revenue as soon as possible,” commented Juan Conchas, Abracon’s Director of Marketing.

Priced competitively, these oscillators range in frequency from 1 to 705.8MHz. Available frequencies are 156.25MHz, 190MHz, 705.8MHz, 100MHz, 125MHz and 114.285MHz for jitter attenuator applications.

Best Phase Noise to Jitter Calculator from Abracon

Abracon Holdings, LLC. (Abracon), a leading global manufacturer of passive & electromechanical timing, synchronization, power, connectivity and RF components has held the industry’s best kept secret: the simplest web-based calculator for intuitive and easy conversion of phase noise to rms phase jitter.

Oscillators for high performance applications such as communications, test and measurement, high performance computing (HPC) and RF systems typically specify single-sided phase noise but may not specify jitter or may not specify over the appropriate integration band. Additionally, some suppliers such as FPGA manufacturers provide phase noise requirements in the form of masks instead of an integrated output jitter requirement. Calculating phase jitter from phase noise becomes necessary when comparing clocks and oscillators for a given application. Abracon’s Phase Noise to Jitter Calculator was designed as an interactive tool that easily bridges the gap between phase noise and jitter. To use the calculator, enter the carrier frequency, integration start and stop offsets, phase offset and phase noise in dB/Hz for a given number of points. The calculator outputs total integrated phase jitter over a specified integration band. A key feature, the integration band is user defined allowing multiple integration bands of interest to be compared.

“Engineers often work with phase noise masks and phase noise requirements instead of phase jitter. They are forced to calculate jitter using spreadsheets or math CAD software,” explains Syed Raza, Abracon’s VP of Engineering. “Our calculator has enabled engineers to interactively manipulate phase noise points and immediately evaluate the integrated phase jitter.”

“As the supplier of industry leading ultra-low phase noise and ultra-low jitter oscillator products,” says Juan Conchas, Abracon’s Director of Marketing, “we saw the need to quickly translate phase noise into phase jitter enabling a simple solution for our FPGA and other high performance customers.”

The calculator also features pre-loaded phase noise profiles of existing oscillators operating at various carrier frequencies. For instance, selecting the AOCJY7TQ-100.000MHz shows an impressive 20fs of output jitter over 12kHz to 20MHz band and an amazing 4.5fs over 1kHz to 1MHz band. To save and compare results, you can export your phase noise plot and output jitter data into a PDF download.

Abracon’s phase noise to jitter calculator has received popular reviews from students and professionals in the field. The company expects to roll out additional features and updates in 2017.
