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 ...

Würth Elektronik has introduced two families of surface-mount multi-channel galvanic isolators for digital signals. Devices in the WPME-CDIP family have four 100Mbit/s isolated channels and a built-in dc-dc converter that provides isolated power from one side to the other. Different versions have different combinations of digital isolator directions: all from input to output, three in that direction and one returning, ...

Infineon has created a 10Gbit/s USB peripheral controller, intended to be used in devices that connect to a host via USB-C. Called CYUSB4014-BZXI, it has an Arm Cortex-M4 processing core, a Cortex-M0+, 1,024kbyte of ram and 512kbyte of flash. Alongside USB-C, it has LVDS, LVCMOS and QSPI serial interfaces, and a crypto processor. This is actually one of four in ...

Diodes has created a series of automotive-compliant PCI Express 3.0 packet switches for in-vehicle networking. “The architecture used enables flexible port configuration with upstream, downstream and CDEP [cross-domain end-point] ports being assigned according to requirements,” according to the company. “They can connect with up to seven different endpoints and support multi-host applications.” PI7C9X3G606GPQ offers 6-port/6-lane operation, PI7C9X3G808GPQ 8-port/8-lane and PI7C9X3G816GPQ ...

Toshiba has introduced a series of multi-channel digital signal isolators that “ensuring stable high-speed digital communications even in the toughest factory floor environments”, it claims. They have 100kV/μs minimum common-mode transient immunity (1.5kV common-mode, 25°C), and carry data rates up to 150Mbit/s. Isolation is 5kV for 1 minute. Called the DCL54xx01 series, they are four-channel devices with different combinations of ...

At Embedded World today, Microchip announced six secure authentication devices that meet Common Criteria Joint Interpretation Library (JIL) secure key storage, and support algorithms that comply with the Federal Information Processing Standard (FIPS). They are intended to be companion devices, compatible with any microprocessor or microcontroller. “This portfolio lowers the barrier to entry and enables developers of products for new ...
