12-Bit, 370 MSPS/500 MSPS, 1.8 V Analog-to-Digital Converter
The ADC requires a 1.8 V analog voltage supply and a differential clock for full performance operation. The digital outputs are LVDS (ANSI-644) compatible and support twos complement, offset binary format, or Gray code. A data clock output is available for proper output data timing.
Fabricated on an advanced BiCMOS process, the AD9434 is available in a 56-lead LFCSP, specified over the industrial temperature range (−40°C to +85°C). This part is protected under U.S. and international patents.
- Wireless and wired broadband communications
- Cable reverse path
- Communications test equipment
- Radar and satellite subsystems
- Power amplifier linearization
- High Performance.
Maintains 65 dBFS SNR at 500 MSPS with a 250 MHz input.
- Low Power.
Consumes only 660 mW at 500 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 provide flexibility in system design. Use of a single 1.8 V supply simplifies system power supply design.
- Serial Port Control.
Standard serial port interface supports various product functions, such as data formatting, power-down, gain adjust, and output test pattern generation.
- The AD9434 is pin compatible with the AD9230, and can be substituted in many applications with minimal design changes.
