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.
"There simply is not anything comparable on the market.
Similar or larger products are geared towards much higher frequencies, not necessary for Standard Definition Video (SDV) applications", said Russ Trayling, Operations Manager at Chyron's Pro-Bel Division.
"Using Fairchild's crosspoint switch has allowed us to not only make Sirius incredibly versatile by switching both SD video and Audio Engineering Standard (AES) audio signals on the same board, but being a single-chip solution, also makes it extremely cost effective".
Fairchild's high-performance SRAM-based OCX256 crosspoint switch features a nonblocking 128 x 128 I/O switch matrix that delivers 667Mbit/s data bandwidth per port.
This CMOS device offers high port count, low power consumption and fast configuration to designers of advanced switching solutions.
The foundation of the OCX device is its silicon-efficient nonblocking crosspoint architecture.
It uses the switch matrix to connect input/output buffers in one-to-one or one-to-many connections.
A special broadcast mode routes a single input to all outputs at the maximum data rate for high-bandwidth applications, while the RapidConfigure parallel interface allows fast configuration of the switch connections.
The OCX256 is available with either LVDS or LVPECL I/O ports, providing flexibility to system and board designers.
Design is further simplified with mainstream CMOS technology that operates at 2.5 and 3.3V, minimising power consumption and heat dissipation.
OCX256 also offers an industry standard JTAG interface that allows engineers to add boundary scan testing to their designs, improving testing and manufacturability.
The Sirius family of routers will be introduced in Europe at the International Broadcasting Convention (IBC) in Amsterdam.
