Digital Integrated Circuits

UK-based Imagination Technologies is aiming at in-car graphics and automated driving, with GPU intellectual property designed to achieve ISO 26262 qualification. For customers seeking such qualification, Imagination is backing the IP with additional investment “in the people, resources, culture and management structure needed to support automotive solutions,” company marketing director Bryce Johnson told Electronics Weekly. “Our testing, documentation and built-in hardware ...

Cadence has introduced DSP intellectual aimed at neural network-based complex speech recognition on the local PCB, without the need for cloud-based services to do the heavy lifting. Resources are sufficient for far-field voice recognition, where the user is metres away from the microphone. Voice-controlled digital home assistants and automotive infotainment are intended applications. Why process speech on the local PCB? ...

Aiming at industrial and automotive applications, Hampshire-based TouchNetix has introduced a high-immunity capacitive touch screen controller that can work with thick screens, and even variable thickness screens – performance that is impossible for modified consumer-grade touchscreen controllers, according to the firm. Claimed noise immunity is far higher than competing controllers – 80dB against typically 50-55dB, company MD Chris Ard told ...

Cypress introduces a seven-port USB-C hub controller with USB Power Delivery

Silicon Labs is aiming at 56Gbit/s PAM-4 serdes and 112Gbit/s serial applications with a set of clock generators, jitter attenuating clocks and voltage-controlled crystal oscillators. Si5391 is an ‘any-frequency’ clock generator with up to 12 outputs and sub-100fs RMS phase jitter. A precision calibrated version (‘P-grade’) typically achieves 69fs RMS phase jitter and can create the primary frequencies needed in 56Gbit/s ...

Microsemi has launched a radiation-resistant matchbox-sized atomic clock

TI has introduced a new automotive Ethernet PHY transceiver that cuts the external component count and board space in half and claims to consume half the power of competitive solutions. The DP83TC811S-Q1’s support for serial gigabit media independent interface (SGMII), small packaging and integrated diagnostic features enable designers to bring greater intelligence via Ethernet connectivity to space-constrained automotive body electronics, ...

Maxim has introduced a partner security chip for microcontrollers. Called the DS28E38 secure authenticator, it includes security keys created on-die by a ‘physically un-cloneable function’ (PUF), which the firm is branding ChipDNA. “We looked at existing PUF designs – we would have bought one, but they fell short,” said Maxim v-p of security business Dan Loomis, who warned of continuing poor IoT ...

Silicon Labs has produced a 'clock tree on a chip' with up to 12 outputs, called Si5332

Silicon Labs is sampling a family of multi-channel jitter attenuating clocks for 4.5G and Ethernet-based Common Public Radio Interface (eCPRI) wireless applications.
