10-Bit, 170/200 MSPS 3.3 V A/D Converter

The AD9411 is a 10-bit monolithic sampling analog-to-digital converter optimized for high performance, low power, and ease of use. The product operates up to a 200 MSPS conversion rate and is optimized for outstanding dynamic performance in wideband carrier and broadband systems. All necessary functions, including a track-and-hold (T/H) and reference are included on the chip to provide a complete conversion solution.

The ADC requires a 3.3 V power supply and a differential sample clock for full performance operation. The digital outputs are LVDS compatible and support both twos complement and offset binary format. A data clock output is available to ease data capture.

Fabricated on an advanced BiCMOS process, the AD9411 is available in a 100-lead surface-mount plastic package (100 e-PAD TQFP) specified over the industrial temperature range (–40°C to +85°C).

Applications

* Wireless and Wired Broadband Communications

* Cable Reverse Path

* Communications Test Equipment

* Radar and Satellite Subsystems

* Power Amplifier Linearization

Product Highlights

* High performance. Maintains 60 dB SNR @ 200 MSPS with a 70 MHz input.

* Low power. Consumes only 1.25 W @ 200 MSPS.

* Ease of use. LVDS output data and output clock signal allow interface to current FPGA technology. The on-chip reference and sample-and-hold function provide flexibility in system design. Use of a single 3.3 V supply simplifies system power supply design.

* Out-of-range (OR). The OR output bit indicates when the input signal is beyond the selected input range.
