Jumpers

3.1.1JMP1: Short R1

In order to allow current output IDAC0 to have full compliance, JMP1 can be used to short out resistor R1, which is in series with that signal.

3.1.2JMP2: Short R2

In order to allow current output IDAC0 to have full compliance, JMP2 can be used to short out resistor R2, which is in series with that signal.

3.1.3JMP3: I2C Data SDA Enable

The MSC1211 uses the same signals for SPI and I2C. Since there is no chip select available for the I2C device, this jumper will allow the isolation of the 256K EEPROM during SPI testing.

3.1.4JMP3: I2C Data SCL Enable

The MSC1211 uses the same signals for SPI and I2C. Since there is no chip select available for the I2C device, this jumper will allow the isolation of the 256K EEPROM during SPI testing.

3.1.5JMP5: AVDD Power Source Select

The MSC1211 has separate analog and digital power supplies. Use JMP5 to connect the desired voltage source for the analog power supply AVDD. Short- ing pins 1 and 2 connects the onboard 5V regulator. Pins 2–3 can be used to

supply an external voltage for use as AVDD; pin 2 is for the external voltage and pin 3 is for AGND.

3.1.6JMP6: DVDD Power Source Select

The MSC1211 has separate analog and digital power supplies. Use JMP6 to connect the desired voltage source for the digital power supply DVDD. Shorting pins 1 and 2 connects the onboard 5V regulator. Pins 2–3 can be used to sup-

ply an external voltage for use as DVDD; pin 2 is for the external voltage and pin 3 is for AGND.

3.1.7J7: Reference Select

J7 has six pins. For normal operation pins 1 and 2 are connected for REF IN– to be connected to AGND. Since the MSC1210 has a very similar pinout to the MSC1210, the MSC1211 board is designed to accommodate the MSC1210 device. For the MSC1210, the VDAC1 pin is the REFOUT pin. Therefore, a connection between pins 3 and 4 will provide the other required connection for use of the internal reference for the MSC1210. Only pins 1 and 2 are needed for the MSC1211. Pins 4 and 6 can be connected together, if you want to use AVDD as the reference voltage.

3.1.8J16: Memory Configuration

The MSC1211EVM can use either RAM or EEPROM in the socket for U9. The J16 jumper provides the capability to configure the Addressing and Write En- able signals for each use. For use with compatible EEPROMs, the following pins are shorted: 1–2, 3–5 and 4–6. For use with the RAM memory that comes stan- dard on the MSC1211EVM, the following pins are shorted: 1–3, 2–4, 5–6.
