This application note explains how to interface AD7276 high-speed data converters to ADSP- 21262 SHARC® processors. This application note also provides example code to demonstrate how the SHARC processor's serial ports (SPI and SPORTs) can be programmed to receive data from AD7276 devices in core and DMA modes.
This document is an Engineer-to-Engineer Note (EE-246) from Analog Devices that details the interfacing of the AD7276 high-speed data converter to the ADSP-21262 SHARC processor. It covers both SPI and SPORT communication protocols, providing specific configuration settings for clock polarity and phase.
| Throughput Rate | 3 MSPS |
|---|---|
| Power Supply Range | 2.35 V to 3.6 V |
| Package Type | 6-lead TSOT |
The AD7276 supports SPI (Serial Peripheral Interface) and SPORT (DSP Serial Port interface) protocols.
The conversion rate is determined by the serial clock SCLK.
