EVM Bill of Materials, Assembly Drawing, and Schematic
The digital control signals can be applied directly to J1 and J5 (top or bottom side). TheADS8364/65MEVM can also be connected directly to the 5-6K Interface Board for use with a variety ofC5000™ and C6000™ series DSP Starter Kits (DSK), or the HPA-MCU Interface Board for use withC2000™ Series DSPs and TMS470™ Series controllers. The Control and Data connectors are designedto allow pattern generators and/or logic analyzers to be connected to the EVM using standard ribbon-typecables on 0.1-inch centers.
The BYTE signal, which controls the output of the ADS836x when used with 8-bit controllers, can bemanipulated with jumper W7. By default, W7 is closed and the BYTE pin is held low, providing data in16-bit format. Removing the shunt at W7 asserts BYTE high by means of pullup resistor R23.
The conversion clock can be applied to J7, a BNC connector with a 50- Ωterminator, or J5 as mentionedpreviously. Jumper W8 allows the EVM user to select the clock source. In normal operation (factorydefault) the shunt on jumper W8 is covering pins 2-3. To use a clock source applied to the BNC connectorJ7, move the shunt at jumper W8 to cover pins 1-2. In either case, the conversion clock can be monitoredat TP21.
Table 5 provides a list of jumpers found on the EVM and their factory default conditions.
Table 5. ADS8364/65MEVM Jumpers
Jumper Shunt Position Jumper Description
W1 Pins 1-2 Controls CHA1(+) input source selection
W2 Pins 1-2 Controls CHA1(–) input source selection
W3 Pins 2-3 Controls reference source (default is internal)
W4 OPEN 3x2 Jumper to control A0, A1, A2
W5 Pins 1-2 Controls BVdd Selection
W6 Closed Controls application of A0, A1 and A2 signals as well as the chip select input. Used in conjunctionwith W4.
W7 Closed Controls BYTE input, opening W7 forces BYTE high via R23
W8 Pins 2-3 Controls application of conversion clock source via J5 or J7
W9 NA W9 pins 2-3 are wired short on the PWB
W10 TIMER 3×3 Jumper to control HOLDx signals – timer or GPIO options available
