-- The AD9410 delivers 10-bit resolution at 210 million samples per second
AD9410 A/D Converter
NORWOOD, Mass., Oct. 23 /PRNewswire/ -- Analog Devices, Inc. (NYSE: ADI - news) today announced a new analog-to-digital (A/D) converter and raised the speed bar for 10-bit converters above the 100 million-samples-per-second (MSPS) mark. The new AD9410 also features on-chip reference and track-and-hold circuitry that make it easier to design high-speed conversion into a variety of communications systems, such as local multichannel distribution service (LMDS) and multipoint multichannel distribution service (MMDS) network applications.

``The AD9410 is suitable for communications systems that require very high data rates like point- to-point radio links,'' said Jon Hall, marketing manager, High-Speed Converter Group, Analog Devices. ``By increasing the effective resolution at this speed, designers can migrate to higher order modulation schemes, such as 64QAM, thus further maximizing their network efficiencies. The AD9410 is easy to work with because this device integrates all the necessary signal blocks that traditionally were separate devices, such as an external sample-and-hold or output data decimator. We expect to see the AD9410 used in communications systems, which will benefit from this level of integration.''
The AD9410 10-bit device can sample at over 200 million samples per second, providing designers of 8-bit IF digitized systems with the ability to opt for higher IF frequencies, which reduces system cost and complexity. ``Those designers who now have systems based on discrete analog implementations can step up to IF digitizing with a higher-resolution, higher-speed, lower- cost solution,'' Hall added.
High Analog Bandwidth and Signal-to-Noise Ratio
This new A/D converter features 500 MHz analog bandwidth and a 54 dB signal-to-noise ratio (with a 99 MHz analog input). The chip operates with +5.0 and +3.3 volt supplies, and produces +3.3 volt CMOS/TTL-compatible outputs. The input signal range is 1.5 volt peak-to-peak differential, but the chip's analog input section is designed to prevent damage and data corruption even when the input is overdriven.
While designers can opt to use an external reference, the AD9410 A/D converter has a built-in 2.5 volt reference. The device's clock can be driven with a differential or single-ended clock signal, but differential clock input assures overall best performance.
Pricing and Availability
The AD9410 A/D converter is available in an 80-pin, surface-mounted, PowerQuadR 2 package. The device, fabricated in advanced BiCMOS IC technology, sells for $53.10 in 1000-piece quantities and is specified to operate over a temperature range of -40 degrees to +85 o C.
