Differential In/Out Connectors (P8–9)
The differential in and out connectors (P8–9) are intended for an evalua-
tion of the AD1939 codec via XLR connectors. A standard, off the shelf
DB25 connector to XLR cables is required; the cable details can be found
in the following table.
MP JTAG Out Connector (P12)
VDDINT Power Connector (P14)
The VDDINT power connector (P14) is used to measure voltage and current
supplied to the processor core. By default, P14 is ON, and the power flows
through the two-pin IDC header. To measure power, remove the jumper
on
P14 and measure voltage across the 0.1 ohm resistor. Once voltage is
measured, power can be calculated. For more information, refer to “Power
Measurements” on page 1-21.
