Hardware Description 1.1 OVERVIEW The MCP3911 ADC Evaluation Board for 16-Bit MCUs system provides the opportunity to evaluate the performance of the MCP3911 dual-channel ADC. It also provides a development platform for 16-bit PIC®-based applications, using existing 100-pin PIC microcontroller Plug-in Module (PIM) systems that are compatible with the Explorer 16 and other high pin count PIC®-based demo boards. The system comes with a programmed PIC24FJ256GA110 PIM module that communicates with the Energy Management Utility software for data exchange and ADC setup. 1.1.1 Feature Highlights • Dual ADC MCP3911 output display using serial communication to the PC software interface • Simultaneous 55 ksps at OSR32 address loop ALL or 95 dB SINAD at OSR512 performance on MCP3911 • System and ADC performance analysis through graphical PC tools showing noise histogram, frequency domain (FFT), time domain scope plot, and statistical numerical analysis • Robust hardware design with analog grounding and analog/digital separation, allowing low noise evaluation of MCP3911 devices; includes separate power supplies and power planes on a 4-layer board. • PICtail™ Plus connectors for Explorer 16 daughter board compatibility  2012 Microchip Technology Inc.

Ports A, B, and D are used for signals such as push buttons, output LEDs, CS and MCLR (for MCP3911 data mode setting). Output Capture 1 is used for clock generation in the MCP3911. Serial communication is achieved through the MSSP module 1. The MCP3911 device is an ADC with a second order modulator and a third order sinc filter, plus a first order sinc filter used for higher OSR’s values. This Delta-Sigma A/D converter has an adjustable oversampling ratio. The CLKIN pin of the MCP3911 is the oversampling clock (MCLK) input. The MCP3911 ADC Evaluation Board for 16-Bit MCUs offers two different options for the MCP3911 master clock (MCLK).  2012 Microchip Technology Inc. DS52033A-page 11 MCP3911 ADC Evaluation Board for 16-Bit MCUs User’s Guide 1.2.1 Using the Crystal X1 The MCP3911 ADC Evaluation Board for 16-Bit MCUs is populated with a 3.58 MHz crystal, used as a clock source, by placing jumpers in the following position on the MCP3911 Digital I/O header block: CLKOUT CLKIN CLKIN FIGURE 1-3: 1.2.2 XTAL XTAL PIM OC1 ADC Clock Selection Jumpers - External Crystal. Driving the Clock with the PIM Module The PIC® MCU can be used to generate the CLKIN (MCLK) signal for the MCP3911, setting the ADC sample rate through the use of the output compare module OC1. To use this feature, make the following jumper change to the MCP3911 Digital I/O header block: CLKOUT CLKIN CLKIN FIGURE 1-4: XTAL XTAL PIM OC1 ADC Clock Selection Jumpers - Clock from MCU. The frequency of the OC1 output is based on the PR1 bits settings in the firmware. DS52033A-page 12  2012 Microchip Technology Inc. Hardware Description 1.3 ANALOG INPUT STRUCTURE Two differential input paths allow external signal sources to be easily connected to the MCP3911 input. Screw-terminal connectors J2 and J5 are 3-pin connectors that act as both screw-type and clip-on post connectors. Note: To use a screw-terminal connector as a post connector, pull up the blue plastic top to access the posts. The connectors J2 and J5 can be used to force either channel from a differential to single-ended configuration. R4 and R11 (on CH0), and R19 and R21 (on CH1) act as locations for burden resistor connectors for any current transformer inputs. 1.4 UNIVERSAL SERIAL BUS (USB) The MCP3911 ADC Evaluation Board for 16-Bit MCUs also contains a USB connection for connecting the evaluation board to a PC. On the board, there is an MCP2200 USB to UART converter that creates a virtual COMM port on the PC. The MCP3911 ADC Evaluation Board for 16-Bit MCUs also features a RS232 connector, just in case it is required. The RS232 line driver is connected to the same UART pins of the MCU. For this reason, a 3-pin jumper (J16) is present on the evaluation board to select which serial communication will be used: USB or RS232. The following figure summarizes the connections between the ADC, MCU, USB to serial converter and the RS232 line driver. USB MCP2200 PIM Module MCP3911 ADC USB TX RX RS232 Driver RS232 RF3/U1TX RF6/SCK1 SCK RF7/SDI1 SDO RF8/SDO1 SDI RF2/U1RX RX TX FIGURE 1-5: USB Block Diagram. The MCP2200 is powered from the USB with 5V. The Q1 transistor (see Appendix A.) is used to disconnect the board from the PC when it is powered down to avoid power consumption. Since the PIC24F runs at 3.3V, a level shifter was used to modify the signal level to 5V as required by the MCP2200; this is done with U11 (see Appendix A.). The 7.3728 MHz value of the crystal is required to achieve the correct baud rate values for higher speed. This design uses a baud rate of 920.6 kbaud and for this baud rate, the register value is 3 (decimal).  2012 Microchip Technology Inc.
