Jumpers
The Hybrid/Local Power jumper is used in conjunction with
mode. Hybrid power mode is used in conjunction with local power mode. Hybrid power allows a node that uses a
local power source from
when the local power source is no longer available. Hybrid power mode is enabled by installing a jumper on pins 1-2
and pins 3-4. Remove all jumpers to disable hybrid power mode. Hybrid power mode is disabled by default.
Hybrid Power ( JP3 )
The Hybrid Power jumper is used in conjunction with
mode. Hybrid power mode is used in conjunction with local power mode. Hybrid power allows a node that uses a
local power source from
when the local power source is no longer available. Hybrid power mode is enabled by installing a jumper on pins 1-2
and pins 3-4. Remove all jumpers to disable hybrid power mode. Hybrid power mode is disabled by default.
Boot ( JP4 )
The Boot jumper allows the ADAU1452 SigmaDSP to perform a self boot, in which it loads its RAM and register
settings from an external EEPROM. When the jumper is installed, no self boot operation is initiated. When the
jumper is removed, a self boot operation is initiated the next time there is a rising edge on the RESET signal of the
ADAU1452 SigmaDSP. This jumper is installed by default.
BCLK ( JP5 )
The BCLK jumper is used to select the routing of the AD2428 BCLK signal. The default setting for the jumper is
pins 3 and 4.
