1.3 WHAT IS THE MCP37XXX HIGH-SPEED PIPELINE ADC DATA CAPTURE CARD (ADM00506)? The MCP37XXX High-Speed Pipeline ADC Data Capture Card (ADM00506) is an FPGA-based memory buffer for the digital data received from the Analog-to-Digital Converter (ADC) evaluation board. Figure 1-1 shows the connection of the data capture card directly between the evaluation board and the PC GUI.

1.4 WHAT IS THE PIPELINE ADC UTILITY SOFTWARE? The Pipeline ADC Utility software is the graphical user interface (GUI) used to communicate with and to configure the operating parameters of the device. The software communicates with the part through the data capture card via a USB cable, allowing the user to program the internal ADC registers.

MCP37X1X-200 12-BIT EVALUATION KIT USER’S GUIDE Chapter 2. Installation and Operation 2.1 MCP37X1X-200 12-BIT EVALUATION KIT FEATURES This MCP37X1X-200 12-Bit Evaluation Kit is a fully assembled, programmed and tested solution (with the exception of a clock source) to evaluate and demonstrate the MCP37X1X-200 operating performance.
MCP37X1X-200 12-Bit Evaluation Kit User’s Guide 2.2 GETTING STARTED 2.2.1 Configuration Requirements To power-up and run the evaluation kit, the following are required: • • • • • • Pipeline ADC Utility Software MCP37X1X-200 12-Bit Evaluation Board (ADM00707) MCP37XXX High-Speed Pipeline ADC Data Capture Card (ADM00506) Two 5V Power Supplies A USB-A to USB Mini-B Cable External Clock Source or Crystal Oscillator (see Section 2.2.4.
2.2.3 Evaluation Kit Set-Up 1. Connect the evaluation board and the data capture card as shown in Figure 2-1. 2. Power up both boards using the supplied 5V Power Supplies. 3. Ensure that a clock input is connected or that a crystal oscillator is installed correctly. Follow instructions in section Section 2.2.4.1 “Optimizing the Clock Connection”. 1: Note: If this is done correctly, the CAL DONE LED will be ON. Otherwise, the user should check the clock input or crystal oscillator for issues. 4.

2.2.4 Input/Output Optimization 2.2.4.1 OPTIMIZING THE CLOCK CONNECTION The evaluation board does not come with a clock source for the device. The user must provide a clock source in order to run this evaluation board. The user has the following options: • Using Microchip’s 200 MHz Clock Source Evaluation Boards: - Microchip’s ADM00725 or ADM00791 evaluation boards may be connected to the external clock SMA input (See Figure 2-1).
