Richardson RFPD Inc. announces immediate availability and full design support capabilities for a new analog-to-digital converter (ADC) from Analog Devices Inc. (ADI).
The AD9249 is a 16-channel, 14-bit ADC with an on-chip sample-and-hold circuit 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 AD9249 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 new ADC contains several features designed to maximize flexibility and minimize system cost, such as a programmable clock, data alignment, and digital test pattern generation. It is ideally-suited for medical imaging, communications receivers, and multichannel data acquisition applications.
Additional key features of the AD9249 include:
- 16 ADC channels integrated into 1 package
- 58 mW per channel at 65 MSPS with scalable power options
- 35 mW per channel at 20 MSPS
- SNR: 75 dBFS (to Nyquist); SFDR: 90 dBc (to Nyquist)
- DNL: ±0.6 LSB (typical); INL: ±0.9 LSB (typical)
- Crosstalk, worst adjacent channel, 10 MHz, −1 dBFS: −90 dB typical
Serial LVDS (ANSI-644, default)
- Low power, reduced signal option (similar to IEEE 1596.3)
- 650 MHz full power analog bandwidth
- 2 V p-p input voltage range
- Serial port control
