VDDEXT Power Connector (P6)
The
VDDEXT
power connector (
P6
) is used to measure the processor’s I/O
voltage and current. By default,
P6
is
ON
, and the power flows through the
two-pin IDC header. To measure power, remove the jumper on
P7
and
measure voltage across the 0.1 ohm resistor. Once voltage is measured,
power can be calculated. For more information, refer to
“Power Measure-
ments” on page 1-27 .
VDDINT Power Connector (P7)
The
VDDINT
power connector (
P7
) is used to measure voltage and current
supplied to the processor core. By default,
P7
is
ON
, and the power flows
through the two-pin IDC header. To measure power, remove the jumper
on
P7
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 1-27 .
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.
