Image processor and sensor module support for AI starters

Fri, Apr 30, 2021

Swiftly following the announcement of the Kria K26 System on module (SOM) and KV260 Vision AI starter kit by Xilinx, Pinnacle Imaging Systems has introduced the Denali 3.0 soft image signal processor and high dynamic range (HDR) sensor module for use with the SOM and kit.

The KV260 Vision AI starter kit was created to help artificial intelligence (AI) innovators streamline development of smart vision applications and rapidly deploy them in production with the Kria K26 SOM. Pinnacle Imaging’s real time HDR imaging capability (up to 120dB) will enable AI developers to capture data-rich imaging streams for neural networks even in high contrast lighting conditions, says the company.

Pinnacle Imaging is also announcing an imager access system (IAS) HDR sensor module, paired with and tuned for the KV260 Vison AI starter kit. Th sensor module is based on ON Semiconductor’s AR0239 CMOS imager which can capture up to 120dB/20EV of dynamic range at 1080p/30 full HD resolution. The sensor captures three exposures per frame which are then merged and tone mapped in the ISP for HDR video optimised for AI-enabled security and surveillance applications.

“Having the powerful capabilities of Pinnacle Imaging’s Denali Soft HDR ISP available on the Kria KV260 starter kit will be invaluable for designers developing next generation vison systems designed to work in variable or difficult lighting conditions.” Chetan Khona, director of industrial, vision, healthcare and sciences at Xilinx.

The Denali 3.0 programmable ISP IP leverages Pinnacle Imaging’s proprietary algorithms to accurately tone map high contrast scenes and extract the full scope of rich image data for mission critical computer vision and AI applications requiring real-time imaging.

“Xilinx is really pushing to democratise these development tools and make them available to a wider audience of innovative thinkers,” said Alfred Zee, CEO of Pinnacle Imaging Systems. “The beauty of our programmable ISP on the Xilinx platform, is that it is easy for us to customise it to meet specific customers’ needs or adapt it to any sensor type, even those with non-traditional colour filter arrays. The AR0239 based IAS HDR sensor module is our first sensor module for this platform, but we expect to support additional sensors in the future based on customer requirements.”

Denali 3.0 delivers real-time video capable of producing up to 120dB or 20-EV steps of dynamic range while ensuring low latency. The HDR IP eliminates halo artefacts and colour shifts to capture up to 1080p HDR video in real time that is fully tone-mapped at 30 frames per second. Denali 3.0 is also able to accommodate automated or full-user control modes.

The Denali 3.0 ISP will be available as a trial download with licensed IP from the Xilinx app store connected to the Kria KV260 Vision AI starter kit from 01 June 2021. Pinnacle Imaging’s AR0239 HDR Sensor module will be available for sale from Avnet.

Rohde & Schwarz validates 5G RRM FR2 conformance tests

Thu, Apr 29, 2021

Conformance tests are vital for mobile communications technology as mobile network operators worldwide rely on conformance to the Global Certification Forum (GCF) before accepting mobile devices in their networks. Rohde & Schwarz has announced that the GCF has approved the first two radio resource management (RRM) conformance test cases for 5G FR2 frequencies, implemented on the R&S TS-RRM-NR 5G RRM conformance test system.

The test cases have been validated in seven FR2 and LTE band combinations.
The availability of validated RRM conformance tests in both FR1 and FR2 frequency bands is crucial for a successful rollout of 5G NR technology worldwide.

The GCF has officially accepted the R&S TS-RRM-NR as suitable for the 5G RRM FR2 requirements described in the 3GPP specifications. The GCF validation process requires ‘pass’ verdicts of the complete test case performed on two different end user devices. The updated version of the R&S TS-RRM family of RRM conformance test systems has accomplished this for FR2. RRM testing is a combination of several protocol and RF test methods. It is used to determine the reaction time of a mobile phone to changes in signal quality from the available sources, and the time it takes for the device to switch between different signal sources.

The new R&S CMX500 radio communication tester has added 5G NR signaling functions for both FR1 and FR2 to the updated R&S TS-RRM-NR, which now covers LTE, WCDMA, and 5G technologies. The integrated test system is operated by the sequencer software R&S CONTEST and offers high efficiency and precise, reproducible measurement results.

The 5G RRM test cases are also supported by the R&S TS8980, the integrated RF conformance test system supporting mobile technologies all the way from 2G to 5G including FR2.

Rohde & Schwarz has supplied conformance and operator acceptance testing throughout mobile radio from 2G through to LTE.

Simplified design for FemtoClock2 lowers power budget for data centres

Wed, Apr 28, 2021

With jitter as low as 64fs RMS, the FemtoClock2 family is available in a small 4.0 x 4.0mm2 24- and 28-pin QFN package options from Renesas Electronics. Power consumption is just 600mW.

The sub-100fs point-of-use clock is designed for data centre, server and network infrastructure markets. The FemtoClock2 family includes low jitter clock generators and jitter attenuators in a single package, enabling cost-effective and simple clock tree implementation for next generation, high speed interconnect designs.

The best-in-class jitter enables customers to easily meet next-generation PAM4 requirements on new switch or router designs, says Renesas. The form factor makes it less than one third the size of similar products available today, says the company. Designers can place the clock source at the point of use – very close to the device receiving the clock signal – for streamlined PCB layout design, reduced cross talk, and cleaner signals. The FemtoClock2 can be configured as a DCO, clock generator, or jitter attenuator.

“PAM4 technology is enabling a major leap in data transmission rates in both communications and data centre segments resulting in stringent requirement on the clock in such systems,” said Bobby Matinpour, vice president of Renesas’ timing products, data centre business division. The small size of the FemtoClock allows it to be placed anywhere on the board at the point of use. “This greatly simplifies the design by eliminating the additive jitter associated with the extensive clock routing on the board,” said Matinpour.

Customers can combine the FemtoClock2 with Renesas’ small, single-output, high-performance oscillators, or the broader ClockMatrix portfolio of timing solutions to address challenging timing needs for their high-performance server and network infrastructure designs. FemtoClock2 also works seamlessly with systems using the recently introduced PTP Clock Manager software for IEEE 1588 support, and can be combined with Renesas’ complementary power and microcontroller offerings to create comprehensive solutions for a variety of applications, such as the IEEE 1588 Winning Combination. FemtoClock2 also serves as the downstream clock capable of delivering 100fs at the pin without disrupting the synchronization.

The RC32504A and RC22504A FemtoClocks and an evaluation board are available now.

Renesas Electronics supplies microcontrollers, analogue, power, and SoC products for automotive, industrial, infrastructure and IoT applications.
