Automotive Ethernet PHY for unshielded pairs
A family of single-chip 10Base-T/100Base-TX Ethernet physical layer transceivers from Microchip are designed for transmitting data over unshielded twisted pair (UTP) cable. For use with inshielded cable, the ICs in the KSZ8061 range include a programmable internal filter to reduce line emissions, which manufacture Microchip has branded ‘Quiet-wire’, for use in automotive networks, industrial networks and ...
Leti strains FD_SOI for more speed and less power
French semiconductor lab CEA-Leti has developed two techniques to induce local strain in FD-SOI (fully-depleted silicon on insulator) for circuits that will produce more speed at the same, or lower, power consumption, and improve performance, it claims. There is compressive SiGe for p-FETs and tensile Si for n-FETs. “In addition to clearing the path to improved ...

12mm² LED for office projectors
Osram has shrunk its projector LED while increasing output power. Ostar Projection Power has 12 mm² of emissive surface and is intended for mainstream projectors rated at >2,500 lm. “This light source is the successor to the P3W,” said the firm. As a monochrome LED it is available in red, converted green and blue. One red, ...

Surface mount switch copes with 5 million operations
Omron has launched two surface mount switches aimed specifically at high use switching applications such as lift push buttons, circuit breakers, digital pens and laser pointers. D2LS switches have a rated life of at least five million operations and can switch at 300 operations per minute. There is a standard version, operating at 0.6N, and ...

UK scientists make fastest THz modulator
The fastest electro-optic THz switch yet has emerged from free electron laser research at the University of Exeter. Graphene, meta-material and plasmonics-based; the exotic device can modulate a THz beam to 60% depth at 40MHz. “40MHz is not fast compared with telecoms modulators, but it is better than state-of-the-art at THz,” Professor Geoff Nash told ...
Relays handle increasing solar loads
Zettler has introduced series of 80, 120 and 200A solar relays for switching ac current in inverters. Contact gaps are wider than the firm’s previous offerings, at 4.6mm for use at up to 5,000m above sea level in the 200A version (pictured). “Zettler is responding to increasing demands for wider contact gaps in solar relays to ...
