SLLSG10 November 2024 TDP142-Q1
ADVANCE INFORMATION
The receiver equalization gain value can be controlled either through I2C registers or through GPIOs. Table 6-2 details the gain value for each available combination when TDP142-Q1 is in GPIO mode. The I2C mode can do the same option or even individual lane EQ setting by updating registers DP0EQ_SEL, DP1EQ_SEL, DP2EQ_SEL, and DP3EQ_SEL.
