The ADS78x1EVM is designed for easy interfacing to multiple platforms. Samtec part numbers SSW-110-22-F-D-VS-K, TSM-110-01-T-DV-P, SSW-116-22-S-D-VS, and TSM-116-01-T-D-V-P provide a convenient dual row header and socket combination at P1, P2, P3, and J3. Consult Samtec at www.samtec.com or 1-800-SAMTEC-9 for a variety of mating connector options.

Connectors P1, P2, and P3 allows the user to plug the EVM into the 5-6k interface card to interface directly with the TMS320C5000 and TMS320C6000 series of DSP. Table 1-4 lists the connector pin out.

Read (RD), conversion start (CONVST) and reset (RESET) signals to the converter can be assigned to two different addresses in memory via jumper settings. The jumper settings allow up to two ADS78x1EVMs to be stacked into processor memory. See Table 1-5 for jumper settings. The evaluation module does not allow the chip-select (CS) line of the converter to be assigned to different memory locations. Instead, ground or wire the CS line to an appropriate signal of the user processor.

The data bus is available at connector P3. Table 1-6 lists the pin out information. This EVM supports two devices but the connector signals names are based on the ADS7981, which is the higher-resolution device. Depending on which device is being evaluated, care must be taken when connecting the EVM to a host processor.

As described in Table 1-7, this evaluation module provides direct access all the analog-to-digital converter control signals via connector J3.
