SLLSFJ8A december 2021 – june 2023 TDP0604
PRODUCTION DATA
The TDP0604 supports both linear and limited redriver. Selection between linear and limited can be done from the LINEAR_EN pin in pin-strap mode or through GLOBAL_LINR_EN register in I2C mode.
The limited redriver mode will decouple TDP0604 transmitter's voltage swing, pre-emphasis or de-emphasis, and slew rate from the GPUs transmitter. This allows the GPU to use a lower power TX setting and depends on the TDP0604 transmitter to meet TX compliance requirements. For source applications, it is recommended to configure TDP0604 as a limited redriver. It is not recommended to use limited redriver mode in sink applications.
Unlike limited redriver mode, in linear redriver mode the TDP0604 transmitter's output is not decoupled from the GPU's transmitter. In linear redriver mode, the TDP0604 transmitter's output is a linear function of its input. For HDMI sink applications, it is recommended to configure TDP0604 as a linear redriver.
For HDMI source applications, it is recommended to use TDP0604 in limited redriver mode.
