POWERING UP THE EVAL-SSM6515Z
To power up the EVAL-SSM6515Z, connect the ribbon cable of the
USBi board to J1 (control port) of the EVAL-SSM6515Z.
POWER
Power can be supplied to the EVAL-SSM6515Z in one of three
ways: connecting the EVAL-ADUSB2EBZ (USBi) board to J11 (see
Figure 20 ), connecting a 3.8 V dc to 5 V dc power supply to J1
(tip positive), or using the binding posts, J2 (5 V) and J10 (GND). If
no external supply is used, the EVAL-SSM6515Z draws power from
the USBi board.
Figure 20. Header J11, Control Port
The on-board regulators generate the 1.8 V, 1.2 V, and 3.3 V dc
supplies. The JP1 and J6 jumpers are used to set the PVDD and
IOVDD supplies to the SSM6515 . By default, the 1.8 V supply is
used for PVDD and IOVDD. The J5 and J18 jumpers provide the
PVDD supply to individual SSM6515 amplifiers, and the J28 and
J29 jumpers provide the IOVDD supply. By removing these jump-
ers, the currents to the individual SSM6515s can be measured.
