Web-based Jitter Measurement Utility gives results in minutes
To use the Jitter Measurement Utility, designers must first create a custom device configuration file with the Timing Commander™ program, also from IDT, then upload the file to the Jitter Measurement Utility page on the IDT website to initiate automated measurement of an evaluation board with the supported device in the company’s Timing lab. Results are typically available in five minutes or less and complete performance reports are sent via email.
“The need for higher timing performance is being driven by the introduction of new technologies such as 5G, mmWave, and 56G PAM-4. The Jitter Measurement Utility enables designers to meet the stringent jitter and phase noise requirements of these applications without setting foot in a lab – they remotely take advantage of ours,” said Bobby Matinpour, vice president and general manager of Renesas’ Timing Products Division. “Our Jitter Measurement Utility is the latest example of our commitment to ensuring product designers can maximize the performance of their systems with our timing solutions, and it complements our Timing Commander software.”
The Jitter Measurement Utility currently supports most of IDT’s programmable timing products, including the VersaClock®, PhiClock™, ProXO™ and UFT™ families.
The recently released ProXO family of programmable, ultra-low noise clock oscillators perform the critical low phase noise clocking functions required by accelerator cards, 100G and 400G switches and routers and optical transceivers used in data center, communications infrastructure, and industrial applications.
ProXO devices are available in multiple package options, including the industry’s smallest XO with sub-120 fs phase jitter performance, measuring just 2.5- x 2.0-mm. The high programmability of the devices gives designers the flexibility to select any frequency including those not readily available in traditional markets. Additionally, the devices have an input voltage range from 1.8-V to 3.3-V and offer four selectable output types (LVDS, CML, LVPECL and HSCL). All of these features are intended to save significant design time and get to market faster.
Additional features of the ProXO family include a self-contained resonator, which eliminates the needs for an external resonator and keeps the footprint small. The analog and digital steerable frequency control simplifies frequency adjustments to synchronize with data recovery clocks and smooths frequency switching to allow frequency tuning on the fly without resetting the system.
