Description
- Product Details
- The AD9249 is a 16-channel, 14-bit, 65 MSPS analog-to-digital converter (ADC) with an on-chip sample-and-hold circuit that is designed for low cost, low power, small size, and ease of use. The device 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 an LVPECL-/ CMOS-/LVDS-compatible sample rate clock for full performance operation. No external reference or driver components are required for many applications.
- The AD9249 automatically multiplies the sample rate clock for the appropriate LVDS serial data rate. Data clock outputs (DCO±1, DCO±2) for capturing data on the output and frame clock outputs (FCO±1, FCO±2) for signaling a new output byte are provided. Individual channel power-down is supported, and the device 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 AD9249 is available in an RoHS-compliant, 144-ball CSP-BGA. It 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. Small Footprint. Sixteen ADCs are contained in a small, 10 mm × 10 mm package.
- 2. Low Power of 35 mW/Channel at 20 MSPS with scalable power options.
- 3. Ease of Use. Data clock outputs (DCO±1, DCO±2) operate at frequencies of up to 455 MHz and support double data rate (DDR) operation.
- 4. User Flexibility. SPI control offers a wide range of flexible features to meet specific system requirements.
- **APPLICATIONS**
- Medical imaging
- Communications receivers
- Multichannel data acquisition
