| Two new 2-port fast Ethernet controllers for embedded Ethernet applications |
 |
| |
 |
|
Asix announced that it has rolled out two new Ethernet IC solutions. The
AX88742 and AX88783 are the latest series being added to the ASIX’s Embedded Ethernet product portfolio. The 2-port Ethernet devices can be configured as a fully managed, Layer-2 switch with the third port being connected to any host processor. Using AX88742 with 32-bit PCI microcontroller or AX88783 with generic 8/16/32-bit microcontroller, designers can provide 2-port Ethernet connectivity to the embedded systems to distribute voice, video, and data remotely over the network. The AX88783 is a 2-port Ethernet switch featuring a third port, 32-bit Non-PCI/SRAM-like host interface. The AX88742 is a 2-port Ethernet switch with the third port being connected to a 32-bit/33MHz PCI host interface.

FT2232D - Dual USB UART/FIFO IC
|
 |
| |
 |
|
The FT2232D is lead free and pin compatible with the original FT2232C and
FT2232L devices. All the original device features are supported with some additional features available including a CPU-style FIFO mode and an extended operating temperature range.
This device features two multi-purpose UART/FIFO controllers which can be configured individually in several different modes. As well as a UART interface, a FIFO interface and the Bit-Bang IO mode of the 2nd generation FT232B and FT245B devices, the FT2232D offers a variety of additional new modes of operation including a Multi-Protocol Synchronous Serial Engine (MPSSE) interface which is designed specifically for synchronous serial protocols such as I2C, JTAG and SPI bus.

VNC1L - Vinculum USB Host Controller Device
|
|
| |
 |
|
The VNC1L USB Host Controller ICs not only handle the USB Host Interface, and
data transfer functions but owing to the inbuilt 8/32-bit MCU and embedded Flash
memory, VNC1L encapsulates the USB device classes as well. When interfacing to mass storage devices such as USB Flash drives, VNC1L also transparently handles the FAT file structure communicating via UART, SPI or parallel FIFO interfaces via a simple to implement command set. The VNC1L device features two USB Ports which can be individually configured by firmware as Host or Slave ports.
VNC1L brings cost effective USB Host capability to products that previously did not have the hardware resources available. We anticipate that these devices will be especially popular for adding USB Flash drive connectivity to a wide range of consumer and industrial products. As VNC1L comes complete with FTDI's in-house developed firmware, there are no USB software stacks to license, indeed, no knowledge of USB is required to use these devices.

USB security dongle ideal for providing application software and physical system access
|
|
| |
 |
|
FTDI announced the availability of its USB-Key security device. Using a unique,
hard-coded identification number, the device can interface to any USB host or
hub to provide application software access control (security dongle) or as part
of a more sophisticated key-based physical access control. During manufacture,
the USB-Key has a unique FTDIChip-ID number burnt into it. This number is only
readable over the USB interface, making it ideal for PC or embedded security
developments. The USB-Key, compatible with USB 1.1 and USB 2.0 specifications,
derives its power from the USB interface and does not require any external
supply or battery.

High speed five-channel digital isolators
|
 |
| |
 |
|
NVE’s IL260-Series five-channel high-speed digital isolators are CMOS devices manufactured with NVE’s patented* IsoLoop® spintronic Giant Magnetoresistive (GMR) technology.
All transmit and receive channels operate at 110 Mbps over the full temperature and supply voltage range. The symmetric magnetic coupling barrier provides a typical propagation delay of only 10 ns and a pulse width distortion of 2 ns, achieving the best specifications of any isolator. The unique fifth channel can be is used to distribute isolated clocks or handshake signals to multiple delta-sigma A/D converters. High channel density makes these devices ideal for
isolating ADCs and DACs, parallel buses and peripheral interfaces.

IL500 Series Digital Isolators
|
|
| |
 |
|
NVE introduced a new series of low cost digital isolators. Targeting the ADI
1Mbps parts, the IL500 series offers many advantages over the competition. The
IL500 series has:
• 2 Mbps data rate.
• A sync function similar to the “refresh” used by ADI. However, the Sync function can be turned on of off to achieve lower noise that the competition and can be linked to other chips on the PCB to ensure any noise is synchronous.
• Better PWD, skew and propagation delay figures
• Narrow and wide SOIC packages as well as MSOP.

New wave of GEN 2 control plane switches
|
|
| |
 |
|
PLX announced its next-generation family of PCIe switches targeting Gen 2
connectivity in high-performance control plane applications, building on the
company’s industry-first Gen 1 chip family. The new PLX® ExpressLane™ PCIe Gen 2 control plane switch family includes three chips -- PEX 8618 (16 lanes, 16 ports), PEX 8614 (12 lanes, 12 ports) and PEX 8608 (eight lanes, eight ports) -- which represent key configurations specified by leading telecommunications and networking designers.

PLX broadens PCI Express GEN 2 portfolio with low-lane-count switches
|
|
| |
 |
|
PLX announced two new PLX® ExpressLane™ PCIe Gen 2 switches with low lane counts: the PEX 8604 (four lanes, four ports), PEX 8606 (six lanes, six ports). The two switches deliver all the unique features available in their higher-lane-count siblings, including the exclusive PLX performancePAK™ and visionPAK™ suites, non-transparency ports, smallest package footprints, and low power requirements. These new low-lane-count PCIe Gen 2 switches are ideal for price-sensitive, mass-production market segments such as set-top boxes, DVRs and multi-function printers. The new PEX 8604 and PEX 8606 low-lane-count, low-power (0.8W typ.) switches include features such as non-transparency (NT), configurable port flexibility (x1 or x2), true peer-to-peer fan-out, and two virtual channels (VCs) per port that help ensure quality of service (QoS). All PLX Gen 2 (5GT/s) switches are fully backward-compatible with the PCIe Gen 1 (2.5GT/s) standard, allowing designers to reap the benefits of this higher-performance technology, even in Gen 1-based systems. Design engineers also benefit from the industry’s most advanced software and hardware development kit (SDK/RDK) products developed specifically to support PLX silicon.

PCIe switches debut with integrated DMA engine
|
|
| |
 |
|
Each switch provides four DMA channels to support the high data rates
required in storage systems, servers, networking, control plane and embedded
markets. By offloading the DMA function typically required of the processor,
PLX's DMA-capable switches increase system performance and create a wide range
of new options for next-generation PCIe designs.
The ExpressLane PEX 8619 (16 lanes, 16 ports), PEX 8615 (12 lanes, 12 ports) and PEX 8609 (eight lanes, eight ports) PCIe Gen 2-compliant switches offer flexible and configurable ports ranging from x1 to x4 on all three devices, with up to x8 on the PEX 8619. The four DMA channels can support high-speed data transfers between I/O devices connected to any of the available ports, while maintaining independence from the unique transparent switch functionality with up to 3-Gbit/s throughput per DMA channel.

ISOdriver Devices Integrate Isolator and 4 Amp Driver into a Single Chip
Si823x ISOdriver family, the industry’s fastest and most integrated isolated gate drivers are ideal for power supplies, motor control and lighting systems, the ISOdriver family integrates a two-channel isolator and dual driver into a single chip while improving power efficiency, enabling customers to increase power supply density and performance.
Traditionally, power system designers rely on expensive, complex multi-die optocouplers that use exotic process technologies and require a discrete bill-of-materials - including an external FET driver. By integrating the isolator and driver into a single chip, the ISOdriver external BOM is reduced to only three capacitors and a diode, allowing an isolated high-side/low-side or dual low-side driver solution that occupies only 200 mm2.
