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 ...

Microchip Technology has added the three more ICs to its TrustFlex secure key provisioning service. Secure key provisioning is putting secret information into ICs at a protected facility. Aimed at companies that do not want to handle their own provisioning, TrustFlex is Microchip’s mid-tier secure provisioning service, for 2,000 units and upwards. The most flexible tier starts at 4,000 units, and ...

Texas Instruments has announced a 9 x 9mm controller IC for the DLP472TP 4K (3,840 x 2,160, UHD) digital micromirror device that it revealed recently. Describing the controller, DLPC8445, as “90% smaller than the previous generation”, the company said that it can be used in lifestyle and gaming projectors “that achieve sub-millisecond display latency, matching or exceeding the world’s most ...

Q-Tech has added high-stability microprocessor compensated crystal oscillators (MCXOs) and oven-controlled crystal oscillators (OCXO) to its product range for low-earth-orbit satellite timing and frequency generation. All are available with either sinewave or CMOS logic outputs. QT2021 is the MCXO series, available in standard frequencies from 10 to 100MHz, Key features are radiation tolerance to 50kRad(Si) TID,  frequency stability over temperature ...

On TSMC’s 7nm process, Alphawave Semi has taped-out an IO chiplet covering UCIe (universal chiplet interconnect express – rev1.1) Ethernet, PCIe and CXL, claiming it to be industry’s first. “Delivering a total bandwidth of up to 1.6Tbit/s, the enables up to 16 lanes of multi-standard PHY supporting PCIe 6.0, CXL 3.x and 800G Ethernet in a combination of mixed operating ...

Renesas is aiming at wireline infrastructure and data centres with a family of 25fs rms jitter 25fs-rms clock generators and jitter attenuators with eight or 12 outputs. RC32312 and RC32308 “provide phase noise and jitter required to meet the needs of 112Gbit/s as well as 224Gbit/s SerDes designs using commonly-available 48MHz to 73MHz crystals”, claimed the company. “The devices can ...

New Yorker Electronics has signed a franchised distribution agreement with Geyer Electronic, a manufacturer of quart crystals, oscillators and resonators. “Founded in 1964 in Munich as a retail store with a range of electronic products, Geyer became a manufacturing company in 1992, specializing in frequency products and special batteries. Ultimately it dropped the batteries line and has concentrated completely on ...

A family of clock generators shifts the focus of SiTime from oscillators. The Chorus family is the second announcement from the company, following its introduction of clock generators in 2020. Oscillators make up 95% of the company’s revenue, explained Piyush Sevalia, SiTime’s executive vice president of marketing, but the acquisition of Indian’s Aura Semiconductor brought its clock products and clock ...

NXP Semiconductors has announced hardware secure element certified to FIPS 140-3 Level 3. “SE052F combines the flexibility of a secure element with the newest generation of the Federal Information Processing Standard, a US and Canadian federal standard for data security required by NIST for participation in federal projects,” said NXP. “Many industrial IoT device manufacturers are turning to certifications, such ...

Texas Instruments has introduced a hex level translator for logic that can also be used as a line-driver. Called SN74LV6T17-EP and part of the LVxT logic family, it contains six independent buffers with Schmitt-trigger inputs. The output level is referenced to the supply voltage, which can span 1.6 to 5.5V and supports 1.8, 2.5, 3.3 and 5V cmos levels. The ...
