Texas Instruments provides a layout and routing guide in the ADS7863IRGET Evaluation Module User's Guide (SLAU445). It recommends a 4-layer PCB with a solid ground plane, and provides guidelines for component placement, routing, and decoupling.
The ADS7863IRGET datasheet provides a detailed section on 'Layout and Design Considerations' (Section 10). Additionally, the Texas Instruments ADC Performance Calculator tool can help optimize the ADC's performance for specific applications.
The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This sequence helps prevent latch-up and ensures proper device operation.
The ADS7863IRGET outputs data in a 16-bit parallel format. The user's guide provides information on data formatting, timing, and synchronization. Additionally, the device's output data can be processed using a microcontroller or an FPGA.
The ADS7863IRGET can operate at a maximum sampling rate of 1.5 MSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and digital output data processing.
