1.2PIM MODULE/MCP3911 CONNECTION AND PERIPHERAL USAGE
OVERVIEW
The MCP3911 ADC Evaluation Board for 16-Bit MCUs contains a 100-pin PIM socket
compatible with Microchip’s PIM modules. The system comes with one PIM module,
the PIC24FJ128GA110.
Ports A, B, and D are used for signals such as push buttons, output LEDs, CS
MCLR
(for MCP3911 data mode setting). Output Capture 1 is used for clock generation
and
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
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).

1.2.1Using 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:
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:
FIGURE 1-4:ADC Clock Selection Jumpers - Clock from MCU.
The frequency of the OC1 output is based on the PR1 bits settings in the firmware.

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.
1.4UNIVERSAL 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.
Hardware Description
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).
