dspblok a9248

Overview

Two Channel High Speed Analog Devices AD9248 ADC I/O Board

The dspblok a9248 is based on an Analog Devices' AD9248 A/D converter. This 14 bit ADC can sample as high 65M/s. Since both channels are sampled synchronously, the dspstak a9248 is ideal for direct conversion or IF sampling receiver applications.

The dspblok a9248 is powered by Danville's dspblok 21469, dspblok 21369zx or dspblok 21369+fpga DSP Modules.

The dspblok a9248 includes expansion connectors for SPI interfacing, UART, and USB for control and programming.

Technical

• Dual 50 Ohm Inputs (SMA Connectors)
• Up to 65M/s Sample Rate
• SPI Expansion Interface
• External Trigger
• Simultaneous Sampling of Both Channels
• On-Board Programmable Clock and External Clock Input
• Fast Sample and Hold Suitable for Undersampling Applications
