MANHASSET, N.Y. The hottest products posted this week at www.eeProductCenter.com include a line of wedge-based LEDs, a family of high-definition multimedia interface ICs, a 10-GHz socket, an ambient light sensor and a newly packaged 8-bit PIC microcontroller chip. This selection was based the largest number of page view clicks to our new products web site.
A line of light-emitting diode lamps from JKL Components Corp. (Pacoima, Calif.) attracted great interest. The LEDs aim at applications that currently use incandescent lamps. The wedge-based LEDs are not subject to breaking and other failure modes associated with incandescent filament lamps, and maintenance costs are minimized by eliminating the need for continued replacement.
Available in 12- and 24-volt versions, the LEDs are offered in T 1-3/4 (series LE-0504) and T-3 ¼ (series LE-0503) sizes. These devices suit applications requiring reduced maintenance and energy costs, as well as applications where high shock and lamp durability are factors, said the company. The LEDs come in bright white, amber, red, blue, green, and ultraviolet.
The lamps are suited for harsh environments including automotive, avionics and marine as well as for aging equipment that requires efficient, long-life lighting technologies. The LEDs offer lifetimes of up to 100,000 hours. Pricing starts at 29 cents each in production quantities.
Poised for emerging high-definition audio and video systems, Analog Devices (Wilmington, Mass.) has extended its line of High-Definition Multimedia Interface ICs with seven new transmitter, receiver and multiplexer chips that support HDMI v1.2a signals up to UXGA resolutions (1600-by-1200 at 60 Hz) and DVI (digital video interface) v1.0.
The AD9889B and AD9389B transmitters, for example, target DVD players, digital video recorders (DVRs), digital cameras, gaming consoles, display projection systems, and cable and satellite set-top boxes. The devices support up to 165 MHz. Both transmitters enable designers to select between internal (AD9389B) and external (AD9889B) high bandwidth digital content protection (HDCP) keys, which protect the integrity of transmissions to prevent unauthorized copying of protected content.
The ADV7441 (10-bit), ADV7443 (12-bit) and AD9388 (10-bit) single-chip receivers integrate all the functions necessary to receive and digitize high-quality video from HD and legacy inputs. The ADV7441 and ADV7443 integrate a multi-format video decoder and graphic digitizer with a dual input HDMI receiver. The video decoder supports NTSC/PAL/SECAM formats with high sensitivity for weak-signal (RF) conditions. The AD9388 integrates a 12-channel analog input component digitizer with a dual-input HDMI receiver. With the capability to support multiple analog and HDMI inputs, the AD9388 will enable connection to VCRs, set-top-boxes, DVD players/recorders, game consoles, A/V receivers and DVRs.
