Figure 1. ADS7953EVM (Left) and ADS7953EVM-PDK (Right)
This users guide describes the characteristics, operation, and use of the ADS7953EVM, ADS7957EVM
and ADS7961EVM, both by themselves and as part of the ADS7953EVM-PDK, ADS7957EVM-PDK or
ADS7961EVM-PDK. These evaluation modules (EVMs) are evaluation boards for the ADS7953, a 12-bit,
16-channel, successive approximation register (SAR) analog-to-digital converter (ADC), and the
and ADS7961, which are 10-bit and 8-bit variations of the ADS7953. The EVM allows evaluation of all
aspects of the ADS7953, ADS7957 or ADS7961 device. Complete circuit descriptions, schematic
diagrams, and bills of material are included in this document.

Page 9: Mmb0 Initial Setup
The MMB0 is a Modular EVM System motherboard. It is designed around the TMS320VC5507, a DSP with an onboard USB interface from Texas Instruments. The MMB0 also has 16MB of SDRAM installed. The MMB0 is not intended to be used as a DSP development board, and it is not available separately. TI cannot offer support for the MMB0 except as part of an EVM-PDK kit. -
