SLLSEA9B February 2012 – August 2015 SN75DP126
PRODUCTION DATA.
The SN75DP126 offers separate AUX and DDC source interfaces that connect to the DisplayPort AUX sink channel and the HDMI DDC sink channel, that seamlessly interface to graphics processor (GPU) comprising separate DDC and AUX interfaces as well as GPUs with combined DDC/AUX. Other sideband circuits such as Hot Plug Detect (HPD) are optimized to reduce external components providing a seamless connection to Intel, AMD, and NVIDIA graphics processors.
The SN75DP126 is optimized for mobile applications, and contains activity-detection circuitry on the DP++ Main Link input that transitions to a low-power Output Disable mode in the absence of a valid input signal. Other low power modes are supported, including a Standby mode with typical dissipation of ~2 mW when no video sink (for example, monitor) is connected.
The device is characterized for an extended operational temperature range from 0°C to 85°C.
At the SN75DP126 HDMI/DVI output, the differential output voltage swing and pre-emphasis levels are configurable. The SN75DP126 output signal conditioning and EQ parameters are programmable through the I2C interface, the VSadj terminal, and the I2C_CTL_EN terminal. The HDMI/DVI sink TMDS output slew rate is controlled by the SRC control input.
