AD9230:  12-Bit, 170 MSPS/210 MSPS/250 MSPS, 1.8 V Analog-to-Digital Converter

Product Details


The AD9230 is a 12-bit monolithic sampling analog-to-digital converter optimized for high performance, low power, and ease of use. The product operates at up to a 250 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 voltage reference, are included on the chip to provide a complete signal conversion solution.

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 either twos complement, offset binary format, or Gray code. A data clock output is available for proper output data timing.

Fabricated on an advanced CMOS process, the AD9230 is available in a 56-lead LFCSP, specified over the industrial temperature range (−40°C to +85°C).

Product Highlights

  1. High Performance—Maintains 64.9 dBFS SNR @ 250 MSPS with a 70 MHz input.
  2. Low Power—Consumes only 434 mW @ 250 MSPS.
  3. 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.
  4. Serial Port Control—Standard serial port interface supports various product functions, such as data formatting, disabling the clock duty cycle stabilizer, power-down, gain adjust, and output test pattern generation.
  5. Pin-Compatible Family—10-bit pin-compatible family offered as AD9211.

    Improve The Design Of Your Passive Wideband ADC Front-End Network
    As converter technology improves, so does the demand to resolve very high intermediate frequencies (IFs) accurately at high speeds. This poses two challenges: the converter design itself and the front-end design that couples the signal content to the converter. Even if the converter itself is excellent, the front end must be able to preserve the signal quality too.
