To drive this ADC in DC-coupled applications, we suggest ADA4937-1. To drive this ADC in AC-coupled applications, we suggest AD8352 or AD8375. To drive this ADC with an IF VGA, we suggest AD8376 or AD8372.

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.

Applications

Wireless and wired broadband communications

The model number is a specific version of a generic that can be purchased or sampled.

Status indicates the current lifecycle of the product. This can be one of 4 stages:

• Pre-Release: The model has not been released to general production, but samples may be available.
• Production: The model is currently being produced, and generally available for purchase and sampling.
• Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
• Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).

The package for this IC (i.e. DIP, SOIC, BGA). An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.
