Digital Interface
The TMS320C6713 DSK provides two memory spaces for the daughterboards. The two memory spaces
enables (CE2 and CE3) are buffered versions of the DSP outputs and are not generated by decode logic
on the DSK. The 5-6K EVM uses CE2 to indicate that the access is valid. The places the daughterboard
at an address space beginning at 0xA0000000.

The pinout for the ADS1610EVM has been arranged to easily mate with the growing range of interface
adapters. The interface board that is currently available is the 5-6K Interface Board (see
SLAU104 ). This
board enables any TMS320C5000 DSP platform or TMS320C6000 DSP platform-based DSK with
standard expansion connectors to connect to the EVM.
The data from the ADC is available at J18 and at J2. J18 is available for interfacing to 5-6K interface
board, user breadboard, or ribbon cable. Connector J2 is installed to allow users to connect the
ADS1610EVM directly to the TSW1100 data capture board (see
SLAU164 ) from Texas Instruments. The
application section of this user’s guide explains how an ADS1610 can be evaluated using the TSW1100
and ADS1610EVM.
The pin assignments and function of each of the pins on J2 and J18 are given in Table 6 and Table 7 .
