Transmitter/Controller Pair Protects Video Transmission From Piracy According to their manufacturer, the SiI 861 PanelLink controller and SiI 168 transmitter enable the transmission of content-protected video without the fear of piracy. These devices form an end-to-end digital visual interface (DVI) solution that features high-bandwidth digital-content protection (HDCP). The SiI 168 operates with any of the company's PanelLink receivers to transmit DVI 1.0 video. Two transmitters can be used in a dual-link mode to achieve data transfers up to 10 Gbits/s, supporting displays with resolutions up to 2056 by 2048. The SiI 861 controller incorporates a PanelLink receiver and supports resolutions up to SXGA and higher with a parallel and integrated low-voltage differential signaling (LVDS) output.Contact the company for pricing and availability information.

Evaluation Kits Help Designers With Low-Power Radio Applications Designed to assist the engineer with low-power radio applications, the RFEVAL1 radio evaluation kits include easy to build telemetry and data communications applications. These applications use a variety of hardware and software encoders and decoders, as well as a variety of radio modules. Three projects are analyzed in detail: simple radio switched relay using a Keeloq HCS360 encoder and HCS512 decoder, remote telemetry switching using a Keeloq HCS360 encoder and PIC16C73 decoder, and radio data communications transmitting a data byte between two PCs. Other features include range testing, target environment testing, antenna evaluation, AM/FM comparison and selection, encoding/decoding testing, and remote switching.Contact the company for pricing and availability information.

5-Pin Modules Safeguard Telecom Network Lines Against Lightning Designed to protect telecom network lines from the effects of lightning, the T5 series of 5-pin protection modules are available in breakdown voltages from 35 to 250 V and overcurrent ratings from 150 mA to 1.2 A. Their plug-in connector is compatible with industry-standard 5-pin protection blocks. According to their manufacturer, their reaction time is 40% faster than conventional power-protection technology that uses gas-discharge tubes. They also reset repeatedly for uninterrupted protection. Other features include a temperature range of -40°C to 65°C, built-in test points on the top of each module, and a completely soldered, no-contact design. Additionally, the modules meet Telecordia 974, GTE GTS-8700, and N.E.C. requirements. They're UL 497 listed as well.Contact the company for pricing and availability information.

IrDA-Compliant Transceiver Pair Features Very Low Profile The TFDS6401 and TFDS6402, a pair of fast infrared IrDA-compliant transceivers, stand just 1.8 mm above the pc board. The chips are housed in the manufacturer's Dracula package, which mounts to the edge of the pc board to reduce the transceiver's height relative to the board. Their data-transmission rates reach up to 4 Mbits/s at 1-m distances.The chips can be used to enable infrared links among and between notebook and palmtop computers, digital still and video cameras, cell phones and pagers, and medical and industrial data-collection devices. Also, they can enable an exchange of files between these mobile systems and desktop computers, printers, fax machines, photocopiers, and set-top boxes. Integrated components include a photo pin diode, a high-power emitter, and low-power analog control circuitry.
Pricing is $3.50 each in 100,000-unit quantities.
