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.
Because the ADC081000 is the fastest, most accurate 8bit ADC at this power consumption level, it is ideal for high-performance applications such as test and measurement and communications equipment.
"With the ADC081000, National is expanding its ADC product offerings into the gigahertz range with an extremely low-power product that enables our customers to eliminate heat sinks, saving both board space and system cost", said Uwe Kopp, Marketing Manager Data Conversion Systems, Europe.
"National's proprietary, analogue-optimised 0.18-micron CMOS process enables us to deliver high-performance ADCs with the lowest power consumption in the industry".
The ADC081000 is the first in a family of gigahertz-range ADCs.
It will be followed by a dual product in the second half of 2004 and higher-speed versions in 2005.
The ADC081000 is designed with an extremely low bit error rate (BER).
At a 1.6GHz sampling rate and input frequencies up to 100MHz, the ADC081000 achieves 0.15LSB differential nonlinearity, 0.35LSB integral nonlinearity and 7.5 ENOB (effective number of bits).
These specifications are especially important in high-speed oscilloscopes.
The ADC081000 also features a novel folding/interpolating architecture.
Folding reduces the number of comparators, and interpolation greatly reduces the number of front-end amplifiers required, saving power and reducing the load on the input signal.
In addition, the ADC081000 has an ideal pulse response and guarantees "no missing codes" over the full operating temperature range of -40 to +85C.
This enables the product's high level of performance and accuracy.
Lastly, the ADC081000 features a National LVDS interface, which enables reliable transmission of high-speed signals, while maintaining low noise and distortion levels.
The ADC081000, housed in a 128-lead exposed pad package, is priced at $100 in 1000-off volumes.
The product is scheduled for full production release in April 2004 and samples will be available then.
