Dual-port Gigabit Ethernet transceiver
National Semiconductor has announced the DP83862, a low-cost, highly integrated dual-port 10/100/1000 physical layer transceiver.
World's smallest multifunction supervisory ICs
National Semiconductor has announced a family of supervisory ICs with a variety of factory-programmable features that can be configured in hundreds of possible combinations.
The low-power LVDS device's superior jitter and signal conditioning performance enables OEMs to use less costly cable, connectors and components.
The DS25CP104 offers a feature set to enhance signal integrity in demanding applications such as XAUI (telecom) and SMPTE 424M (pro video).
For example, the product consumes only 122mW per channel while boosting and equalising field-programmable gate array (FPGA) or application-specific integrated circuit (ASIC) signals over cables and FR-4 backplanes.
The device inputs have a wide common-mode voltage range that allows it to accept low-voltage positive emitter coupled logic (LVPECL), current-mode logic (CML), and LVDS signal levels without using coupling capacitors.
The system designer has maximum flexibility configuring the DS25CP104 with external pin control or a serial system management (SM) Bus.
The crosspoint also features 8kV electrostatic discharge (ESD) protection and 100ohm termination on the LVDS input and output pins to minimise insertion losses, component count and board space.
National also is introducing the DS10CP154, a lower speed, lower power 4 x 4 crosspoint switch targeted at applications up to 1.5Gbit/s.
It includes many of the same features as the DS25CP104.
