AD9958/PCB
Manual I/O Control Headers
Provides the interface for communication with the AD9958
when the part is under the control of an external controller
(manual control). See Eval Board Control for correct jumper
settings.
Multidevice Synchronous Control
These connections set up the AD9958 for multidevice
synchronous operation.
Clock Input Supply
Powers the AD9958’s clock input circuitry.
Clock Mode Select
Controls whether the part is driven by a 20 MHz to 30 MHz
crystal provided by the user or by an external signal generator
such as REF_CLK.
REF_CLK Input
Input for the external REF_CLK signal.
Band Gap Supply
Provides the voltage needed for band gap functionality.

Power Supply
Powers the AD9958’s USB circuitry, I/O circuitry, and the
digital portion (DVDD) of the DACs. Note AVDD is not
powered via this connector (TB1).
DAC Channels
These connections represent the DAC filtered/unfiltered output
and AVDD power supply.
RU/RD Control, SDIO
Jumper W6, Jumper W5, and Jumper W4 must be set to control
the Ramp Up/Ramp Down feature using the SDIO pins.
USB Port
When the part is under PC control (default mode), the evaluation
board communicates with the AD9958 via this port.
Eval Board Control
These jumpers set up the AD9958 for manual or PC control
(control through the USB port). Figure 2 shows the correct
jumper placements for PC control. For manual control, remove
Jumper W0 to Jumper W3; set Jumper W7 on the manual
control pin (move jumper one position to the left).
