Toshiba is aiming at UART and SPI interfaces with three four-channel dual-supply level-translator-transceivers. “The bus transceivers support level-up and level-down voltage translation from either of their dual power supplies in bidirectional communication systems using signal voltages between 0.8V and 3.6V,” said Toshiba. “These devices have been designed without any restrictions on the on-off sequencing of power supply terminals Vcca and ...

Microchip has combined a chip-scale caesium atomic clock for good accuracy with a ovened crystal oscillator for good phase noise, in a through-hole package measuring 0.4 x 50.4 x 12.7mm (2 x 2 x 0.5inch, both plus pins). The crystal oscillator “offers phase noise at 10Hz [of] <-120 dBc/Hz and Allan deviation stability of <10-11 at a 1s averaging time. ...

Infineon is claiming ‘world’s smallest GSMA-compliant’ e-SIM IC for its OC1230, which measures 1.8 x 1.6 x 0.4mm and is made on a 28nm process. Inside is an Arm v8 processor and Infineon’s ‘Integrity Guard 32’ intellectual property. Security is evaluated according to BSI-CC-PP-0100-2018 specified in GSMA SGP.25, said Infineon, which added that it is based on post-quantum-cryptography-ready hardware. GSMA ...

SiTime has introduced SiT5977, a ±1ppb/°C mems-based 156.25MHz oscillator for network timing in data centres. It is “capable of driving 800G and higher links via 80fs phase jitter and LVDS outputs,” according to the company. Inside the tiny package, which measures 3.5 x 5mm, is what is claimed to be “the world’s most accurate silicon temperature sensor”. This sensor consists ...

ADI is aiming at Industrial Ethernet with ADIN6310, a deterministic six-port switch that implements TSN (time sensitive networking) and security. “TSN facilitates a single converged network where both mission-critical real-time and non-real time data co-exist,” according to the company. “Redundancy features allow for fail-over and increased network up-time, while the packet assist engine off-loads the host processor.” The IC has ...

PhotonDelta, the European hub for photonics, will launch a worldwide competition for new applications for photonics chips at PIC Summit 2024 (Eindhoven 15 October). Partners include imec, LioniX International, Smart Photonics, Phix Photonics Assembly, Ephiphan and Bright Photonics and engineering community platform Werolver. Engineers are invited to use photonics ICs in designs to tackle challenges in, for example, healthcare, AI, ...

SiTime has announced a series of clock generators for automotive systems, calling them: “Industry’s first integrated clock system-on-a-chip with built-in fault monitoring mechanisms for the entire clock generation signal path, with the capability to alert a safety microcontroller of a clock-related fault within microseconds instead of milliseconds.” The devices, branded Chorus, include a MEMS resonator, oscillator and safety mechanisms into ...

U-blox has created an all-band all-constellation precision GNSS receiver, a successor to its F9 IC with L6 reception and global precision coverage. X20, as it will be known, “addresses the current high-precision GNSS needs around the world, and its design is equipped to also handle new and emerging technologies and standards”, according to the company. “The platform is designed for ...

Toshiba has created a pair of 32Gbit/s multiplexer/demultiplexer switches, intended to switch two differential pair signal paths, or four single-ended signal paths, between a single port on one side and two ports on the other. The devices are aimed at high speed serial busses including PCIe 5.0/4.0, CXL 2.0/1.0,  USB4 Version 2.0, Gen3/Gen2, USB 3.2 Gen 2/Gen 1,  Thunderbolt 4, ...

Microchip is aiming at automotive single-pair Ethernet links up to 40m long with a 7 x 7mm transceiver ICs called LAN8870B. Single-pair Ethernet is also being used in avionics, robotics and automation, it said. “For interoperability across industries, LAN887x PHYs are designed to be compliant with IEEE 802.3bp for the 1000BASE-T1 specification, and IEEE 802bw-2015 for the 100BASE-T1 specification*,” according ...
