TERMINAL FUNCTIONS
TERMINAL
TYPE DESCRIPTION
NAME NO.
DC/DC output. The 5-V power pin can supply 55 mA regulated current to the HDMI
5VOUT F1 Power Out receiver. Separate DC/DC converter control pin CT_CP_HPD disables the DC/DC
converter when operating at low-power mode.
CEC_A B2 I/O System-side CEC bus I/O. This pin is bi-directional and referenced to V
CCA
.
HDMI-side CEC bus I/O. This pin is bi-directional and referenced to the 3.3-V internal
CEC_B D3 I/O
supply.
High-speed ESD clamp: provides ESD protection to the high-speed HDMI differential
CLK–, CLK+ G4, F4 ESD
data lines
DC/DC Enable. Enables the DC/DC converter and HPD circuitry when CT_CP_HPD =
CT_CP_HPD D1 Control
H. The CT_CP_HPD is referenced to V
