EVM Overview The ADS1202 modular EVM provides direct modulator output to a host processor and allows all operating modes of the ADS1202. It provides various isolation options for a variety of applications. The new modular EVM form factor allows for direct evaluation of the ADC’s performance and operating characteristics. -
Page 10: Analog Interface
Analog Interface 1.1 Analog Interface The ADS1202 modular EVM is designed for easy interfacing to multiple analog sources. Samtec part numbers SSW-110-22-F-D-VS-K TSM-110-01-T-DV-P provide a convenient 10-pin dual row header/socket combination at J1. Connector J1 provides access to the ADS1202 input pins. -

ADS1202. The digital control signals can be applied directly to J2 (top or bottom side). The ADS1202 modular EVM can also be connected directly to a DSP interface board. Footprints are provided on the PWB which allow a variety of isolation options. - Page 14 Using an oscilloscope view the MCLK and MDAT output signals on J2.5 and J2.13 respectively. The outputs should look similar to those in the following figure: Slowly increase the time base of the oscilloscope. As the time base increases, the sine wave applied to the input terminals should begin to appear on the oscilloscope screen as shown below.
