The AD9222 is an octal, 12-bit, 40/50/65 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 65 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 and typically consumes less than 2 mW when all channels are disabled.
The ADC contains several features designed to maximize flexibility and minimize system cost, such as programmable clock and data alignment and programmable digital test pattern generation. The available digital test patterns include built-in deterministic and pseudorandom patterns, along with custom user-defined test patterns entered via the serial port interface (SPI).
The AD9222 is available in an RoHS compliant, 64-lead LFCSP. It is specified over the industrial temperature range of -40°C to +85°C.
- Small Footprint. Eight ADCs are contained in a small, space-saving package.
- Low power of 114 mW/channel at 65 MSPS.
- Ease of Use. A data clock output (DCO) is provided that operates at frequencies of up to 390 MHz and supports double data rate (DDR) operation.
- User Flexibility. The SPI control offers a wide range of flexible features to meet specific system requirements.
- Pin-Compatible Family. This includes the AD9212 (10-bit) and AD9252 (14-bit).
- Medical imaging and nondestructive ultrasound
- Portable ultrasound and digital beam-forming systems
- Quadrature radio receivers
- Diversity radio receivers
- Tape drives
- Optical networking

Evaluation Kits (2)
This page contains evaluation board documentation and ordering information for evaluating the AD9222.
The HSC-ADC-EVALCZ high speed converter evaluation platform uses an FPGA based buffer memory board to capture blocks of digital data from the Analog Devices high speed analog-to-digital converter (ADC) evaluation boards. The board is connected to the PC through a USB port and is used with VisualAnalog® to quickly evaluate the performance of high speed ADCs. The evaluation kit is easy to set up. Additional equipment needed includes an Analog Devices high speed ADC evaluation board, a signal source, and a clock source. Once the kit is connected and powered, the evaluation is enabled instantly on the PC.
