SNLS645A August 2019 – December 2019 DS160PR410
PRODUCTION DATA.
If EN_SMB = L3 (SMBus / I2C control mode), the DS160PR410 is configured through a standard I2C or SMBus interface that may operate up to 400 kHz. The slave address of the DS160PR410 is determined by the pin strap settings on the EQ1_ADDR1 and EQ0_ADDR0 pins. The device can be configured for best signal integrity and power settings in the system using the I2C or SMBus interface. The sixteen possible slave addresses (8-bit) for the DS160PR410 are shown in Table 5.
