MoCA 1.1 spec improves HD home video network performance Design How-To 2/22/2008 Post a comment MoCA 1.1, backwards compatible with 1.0, almost doubles capacity. Two key enhancements address the need for bandwidth to support multiple HD streams within the home LAN and ensure that video traffic is never compromised during situations where heavy, but less time-critical, traffic arises.
LED driver extends battery life by up to 10% Product News 2/21/2008 Post a comment Leadis Technology has started to sample the LDS8860, a charge-pump based 6-channel LED driver that implements the company's proprietary PowerLite Current Regulator to deliver up to 91% power efficiency for longer battery life.
Analog's answer to FPGA opens field to masses News & Analysis 2/21/2008 Post a comment By making analog circuits easier to design and simulate, researchers at the Georgia Institute of Technology hope to further the cause of analog while enabling engineers to incorporate lower-power circuitry into their products. In the same way that field- programmable gate arrays have spawned advances in digital signal processing, the Georgia Tech researchers believe their large-scale field-programmable analog array (FPAA) has the potential to seed growth in analog.
CDR chip simplifies XFP module design Product News 2/20/2008 Post a comment Inphi's 3200EC is a 10-Gbit/s dual CDR with EDC engine that when coupled with its 1348TA linear TIA reduces development costs and accelerates delivery of standards-compliant 10GBASE-LRM XFP modules.
Fuel gauge integrates LED drivers Product News 2/20/2008 Post a comment Maxim is calling its DS2788 the industry's smallest stand-alone fuel gauge to integrate LED drivers and a pushbutton input for multiple Li+ cells into a single IC.
The nuts and bolts of HDCP Design How-To 2/20/2008 Post a comment As the digital distribution of television, movies and music expands, content providers are growing increasingly concerned about the simplicity with which content pirates can copy and share copyrighted material. Various digital rights management (DRM) schemes have been developed. To protect digital content as it's transmitted over cables between devices, Intel developed a DRM scheme known as the High-bandwidth Digital Content Protection system (HDCP).
