10 Power Supply Recommendations

The designer needs to consider the requirement for the HDMI Transmitters Hot Plug Detect (HPD) scheme. If it is a requirement, then the VIH of HPD on the core scalar chip is the minimum voltage needed to detect a Hot Plug event. The minimum voltage requirement is V5V_SUPPLY — VDROP_MAX — VDROP_SYSTEM — VON_MAX > VIH ⇒ V5V_SUPPLY > VIH + VDROP_MAX + VDROP_SYSTEM + VON_MAX ; where VDROP_MAX is the maximum voltage drop across TPD12S521's current limiter, VDROP_SYSTEM is the voltage drop across the path from Pin 38 of TPD12S521 through the sink and back to Pin 20, and VON_MAX is the maximum voltage drop across TPD12S521's level shifting NFET when ON. Otherwise, TPD12S521 is a passive ESD protection device and there is no need to power it.
