INTERCONECTS Rapid media converters support Ethernet applications in realtime With their short latency, the FL MC 2000T Ethernet media converters from Phoenix Contact have been specially optimized for use in applications with time-critical protocols. The optical converters are optionally available with pass through operating mode. This enables the latency to be halved in comparison to standard mechanisms such as store-and-forward. As a result, they are suitable for Ethernet protocols such as Profinet, Powerlink, Ethercat or Sercos lll. The devices are in robust metal housing and satisfy high environmental requirements for implementing a variety of applications. Distances of up to 40 kilometers can be bridged using single-mode fiberglass. In addition to numerous diagnostics LEDs, the media converters feature the Link Fault Pass Through function. This provides permanent connection monitoring. If the connection drops, direct redundancy measures can come into play. A relay output on the device also informs you of a voltage or connection drop. Data transmission via fiber optics optimizes Ethernet applications with regard to their performance and transmission reliability. In addition to the increased range, the advantages of electrical isolation are also apparent. Phoenix Contact www.phoenixcontact.com Hermetic-sealed multi-fibre connection systems Molex’ Hermetic-Sealed Multi-Fibre Circular MT Optical Assemblies promise extreme sealing performance in the smallest footprint. These assemblies provide system reliability in extreme environments, including severe weather conditions, high altitudes and high atmospheric pressures. These conditions can cause ordinary surveillance and sensor equipment to fail, which can create critical communications problems. Hermetic sealing can address this problem, but only under certain circumstances. Hermetic-Sealed Multi-Fibre Circular MT Optical Assemblies contain 12 to 24 fibres in one smallfootprint connector compared with similar products that utilise discrete-fibre (one fibre per contact) connector designs. The assemblies are appropriate for applications that require optimal environmental and pressure-sealing capabilities, such as aerospace and defence, mining, oil and gas exploration, industrial process control, and medical. They can operate in temperatures ranging from -40° to 70° C. A Multi-Fibre MT interface with 12 to 24 flat-ribbon fibre counts provides the densest fibre count in a compact hermetic interface for maximum data transfer. This suits the HSMFC MT Optical Assemblies for tight panel configurations where space is at a premium. Sealing rates are to 1x10-6 helium (He) cc/s at one atmosphere differential pressure. Stainless steel connector housings provide high durability and corrosion resistance. Molex www.molex.com/link/hermeticsealed.html Phase matched cable assemblies from DC to 50GHz The Cable Assembly division of Intelliconnect (Europe) Ltd, the UK based specialist manufacturer of RF connectors, now offers phase matched cable assemblies. This allows customers to specify the electrical length in time or degrees at the frequency of operation for a specific cable assembly. Phase matching of a cable assembly is essential when connecting to multi-channel receivers as it is important for discrete channels to match and track each other over frequency of operation. Cables can be matched in “sets” or pairs. One of two methods may be used - electrical length (matched to a golden standard), or phase matched to another cable. Applications for phase matched cable assemblies include high power amplifiers, RF combiners and filters, multi-beam antenna arrays, phased array radars. Coaxial, triaxial and multi-way connectors may be specified and fully immersible waterproof versions are available. All Intelliconnect cable assemblies are 100% electrically tested before despatch. In addition phase matching is available where required to ensure signal integrity in individual, or batches of, assemblies. Intelliconnect www.intelliconnect.co.uk USB 3.0 interface in 56-pin QFN package The FT600Q and FT601Q are FTDI Chip’s first generation USB 3.0 products that function as SuperSpeed USB 3.0 to FIFO bridges, providing data bursting rates of up to 3.2Gbps. The FT600Q comes in 56-pin QFN package and has a 16-bit wide FIFO bus interface, while FT601Q comes in 76-pin QFN package and has a 32-bit wide FIFO bus interface. Both these chips support up to 8 endpoints, other than the management endpoints. The endpoints are linked to a configurable endpoint buffers of 16kByte length for IN and 16kByte for OUT. Both FT600Q and FT601Q support two interfacing modes; the 245 FIFO mode and the multi-channel FIFO mode, and thus provide more flexibility for system designers. The 245 FIFO mode has a simpler protocol, but for more sophisticated customers, the multi-channel FIFO mode supports up to 4 logical FIFO channels and data structures optimised for higher throughputs. The FIFO is provided with a 16kByte configurable buffer. The remote wake up function on these chips can be used to rapidly bring the USB host controller out of suspend mode. The USB battery charger detection function enables USB peripheral devices to detect the presence of a higher current power source in order to boost charging capabilities. It means that the FT600 can detect connection to a USB-compliant dedicated charging port (DCP) and transmit a signal allowing external logic to switch to charging mode. The IC can also benefit from the higher power delivery capabilities that the USB 3.0 standard supports while still being able to transfer data.
