Santa Clara, Calif.National Semiconductor Corp. added three signal-conditioning buffers to its low-voltage differential signaling (LVDS) product portfolio.
According to National, the DS25BR100, DS25BR110 and DS25BR120 buffers are the industry's first LVDS devices to offer transmit pre-emphasis and receive equalization for jitter performance up to 3.125-Gbits/s, while using less power than previous-generation buffers.
National's DS25BR100, DS25BR110 and DS25BR120 are single-channel LVDS buffers that provide enhanced signal integrity up to 3.125 Gbits/s. They offer jitter performance at 9 picoseconds (ps) typical and low power at 100 milliwatts.
National optimized the DS25BR100, DS25BR110 and DS25BR120 LVDS buffers for high-speed signal transmission over FR-4 backplanes and cables used in communications, storage and imaging systems. For example, they drive 2.5-Gbits/s transmissions over 10 meters of InfiniBand cable or 40 inches of FR4, with 0.15 units interval (UI) of residual jitter at the equalizer output. They can also boost signals in next-generation serial digital interface (SDI) broadcast video routers and home theatre digital visual interface (DVI) cable interconnects.
The DS25BR100, DS25BR110 and DS25BR120 LVDS buffers provide 7 kV of electrostatic discharge (ESD) protection and are well-suited for buffering signals from the new generation of 90-nm and 65 nm FPGAs and ASICs.
The 3.125 Gbits/s DS25BR1xx devices are housed in a small 3 mm x 3 mm 8-LLP space-saving package.
Pricing: $2.45 each in 1,000-unit quantities.
Data Sheets: DS25BR100, DS25BR110 and DS25BR120.
