EVM Bill of Materials, Assembly Drawing, and Schematic

The digital control signals can be applied directly to J1 and J5 (top or bottom side). The ADS8364/65MEVM can also be connected directly to the 5-6K Interface Board for use with a variety of C5000™ and C6000™ series DSP Starter Kits (DSK), or the HPA-MCU Interface Board for use with C2000™ Series DSPs and TMS470™ Series controllers. The Control and Data connectors are designed to allow pattern generators and/or logic analyzers to be connected to the EVM using standard ribbon-type cables on 0.1-inch centers.

The BYTE signal, which controls the output of the ADS836x when used with 8-bit controllers, can be manipulated with jumper W7. By default, W7 is closed and the BYTE pin is held low, providing data in 16-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 mentioned previously. Jumper W8 allows the EVM user to select the clock source. In normal operation (factory default) the shunt on jumper W8 is covering pins 2-3. To use a clock source applied to the BNC connector J7, move the shunt at jumper W8 to cover pins 1-2. In either case, the conversion clock can be monitored at TP21.

6.1Default Jumper Locations

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 conjunction
		with 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
