JAJSKH4A April 2022 – May 2024 TUSB1104
PRODUCTION DATA
A typical usage of the TUSB1104 device is shown in Figure 7-2. The device can be configure either through its GPIO pins or through its I2C interface. In the following example, a Type-C PD controller or microcontroller is used to configure the device through the I2C interface. In I2C mode, the equalization settings for each receiver can be independently controlled through I2C registers. For this reason, all of the equalization pins (SSEQ[1:0], and CEQ[1:0]) can be left unconnected. If these pins are left unconnected, the TUSB1104 7-bit I2C target address will be 0x12 because both SSEQ1/A1 and SSEQ0/A0 will be at pin level F. If a different I2C target address is desired, SSEQ1/A1 and SSEQ0/A0 pins should be set to a level which produces the desired I2C target address.
