Multipoint-LVDS Single-Channel Receivers from TI

Multipoint-LVDS Single-Channel Receivers from TI
Texas Instruments has introduced what is said to be the industry's first dedicated multipoint-LVDS receivers. To date, customers converting M-LVDS to LVTLL for multi-drop clock distribution have used transceivers with unnecessary integrated driver circuitry. The new single-channel receivers save space, power consumption and cost in end equipment such as cellular base stations, central office switches, network switches, routers and AdvancedTCA systems. The devices provide better technical performance in applications such as clock and synchronization distribution and control, as well as data signal transfer over backplanes and cables.

Single chip Ethernet controller

 Single chip Ethernet controller
Available from DT Electronics, SMSC’s LAN9218 is a full-featured, single-chip 10/100 Ethernet controller that uses HP’s Auto-MDIX technology. HP Auto-MDIX eliminates the confusion associated with device pin assignments, the need to add a manual MDIX switch or use cross-over cables. The LAN9128 is driver-, register- and footprint –compatible with the previous generation of LAN9118 devices. Designed for embedded applications where performance, flexibility, ease of integration and system cost reduction are required, the LAN9218 suits applications in high definition video and multimedia systems.
