The AD9645 is a dual, 14-bit, 80 MSPS/125 MSPS analog-to-digital-converter (ADC) with an on-chip sample-and-hold circuit designed for low cost, low power, small size, and ease of use. The product operates at a conversion rate of up to 125 MSPS and is optimized for outstanding dynamic performance and low power in applications where a small package size is critical.

The ADC requires a single 1.8 V power supply and LVPECL-/CMOS-/LVDS-compatible sample rate clock for full performance operation. No external reference or driver components are required for many applications.

The ADC automatically multiplies the sample rate clock for the appropriate LVDS serial data rate. A data clock output (DCO) for capturing data on the output and a frame clock output (FCO) for signaling a new output byte are provided. Individual channel power-down is supported; the AD9645 typically consumes less than 2 mW in the full power-down state. The ADC provides several features designed to maximize flexibility and minimize system cost, such as programmable output clock and data alignment and digital test pattern generation. The available digital test patterns include built-in deterministic and pseudo-random patterns, along with custom user-defined test patterns entered via the serial port interface (SPI).

The AD9645 is available in a RoHS-compliant, 32-lead LFCSP. It is specified over the automotive temperature range of −40°C to +105°C.

PRODUCT HIGHLIGHTS

  1. Small Footprint. Two ADCs are contained in a small, space-saving package.
  2. Low Power. The AD9645 uses 122 mW/channel at 125 MSPS with scalable power options.
  3. Pin Compatibility with the AD9635, a 12-Bit Dual ADC.
  4. Ease of Use. A data clock output (DCO) operates at frequencies of up to 500 MHz and supports double data rate (DDR) operation.
  5. User Flexibility. The SPI control offers a wide range of flexible features to meet specific system requirements.

Product Detail

The AD9645-125EBZ is an evaluation board for the AD9645, dual 14-bit ADC. This reference design provides all of the support circuitry required to operate the devices in their various modes and        configurations. It is designed to interface directly with the HSC-ADC-EVALC data capture card, allowing users to download captured data for analysis. The Visual Analog software package, which is used to interface with the device's hardware, allows users to download captured data for analysis with a user-friendly graphical interface. The SPI Controller software package is also compatible with this hardware, and allows the user to access the SPI programmable features of the AD9645.

The AD9645 data sheet provides additional information related to device configuration and performance, and should be consulted when using these tools. All documents and Visual Analog and SPI Controller are available at the High Speed ADC Evaluation Boards page. For additional information or questions, please email highspeed.converters@analog.com.
