The AD9643 is a dual, 14-bit analog-to-digital converter (ADC) with sampling speeds of up to 250 MSPS. The AD9643 is designed to support communications applications, where low cost, small size, wide bandwidth, and versatility are desired.

The dual ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. A duty cycle stabilizer is provided to compensate for variations in the ADC clock duty cycle, allowing the converters to maintain excellent performance.

The ADC output data is routed directly to the external, 14-bit, LVDS output port and formatted as either interleaved or channel multiplexed.

Flexible power-down options allow significant power savings, when desired.

Programming for setup and control are accomplished using a 3-wire SPI-compatible serial interface.

The AD9643 is available in a 64-lead LFCSP and is specified over the industrial temperature range of −40°C to +85°C. This product is protected by a U.S. patent.

Product Highlights

  1. Integrated dual, 14-bit, 170 MSPS/210 MSPS/250 MSPS ADCs.
  2. Operation from a single 1.8 V supply and a separate digital output driver supply accommodating LVDS outputs.
  3. Proprietary differential input maintains excellent SNR performance for input frequencies of up to 400 MHz.
  4. SYNC input allows synchronization of multiple devices.
  5. 3-pin, 1.8 V SPI port for register programming and register readback.
  6. Pin compatibility with the AD9613, allowing a simple migration down from 14 bits to 12 bits. This part is also pin compatible with the AD6649 and the AD6643.
