5 SMBus Slave Mode of the EQ, VOD, and De-Emphasis level:

• Set ENSMB = 1 (1kΩ to VIH) by using the SW2 (3-2-1) = (OFF-OFF-ON).

• Set SW4 pin1,2 to the ON position so the SMBUS signals are connected.

• Set SW3 pin1 thru pin6 switches to the OFF position so they do not connect to the SDA and SCL line.

• Set the SW1 and SW5 for the AD[3:0] pins. AD[3:0]=0000 sets device slave address = B0’hex.

• Connect SDA, SCL and GND to J17. Please refer to datasheet for register map for EQ, VOD and

DEM.
