Pin control mode has only automatic port selection. I2C control mode has automatic port selection. In auto port selection, when only one HPD high detected, the port with HPD high will be selected. When multiple HPD high detected, the PRI_SEL pin (priority select) will determine the priority of the 2 ports. See priority selection table When PRI_SEL=low or High, the port-priority will be port1-port2 from high to low; when PRI_SEL=M (open as not connected), the port priority will be port2-por1 from high to low. When port 1 is selected and CAB_1 is low as in DP mode, the AUX/DDC channels will work as AUX channels. AUXP shall have 100Kohm external resistor to GND and AUXN shall have 100Kohm external resistor to VDD. The data rate of AUX channels will be >720Mbps.The internal DDC switch will be off. When port 1 is selected and CAB_1 is high when DP to HDMI adapter plugged, the AUX/DDC channels will work as DDC channels. The internal DDC channels are on and the AUX channels are off. The input of DDC channels can tolerate 5V input and voltage of DDC to source will be limited about 3.3V or below. When port 1 is selected (passive ports), port2 with HDMI re-driver will shut down. When port 2 is selected, the internal DP to HDMI level shifter will be enabled. There will be 3 EQ and 3 Pre-emphasis settings in pin control mode, 8 EQ and 5 Pre-emphasis settings in I2C control mode. When port 2 is selected, HDMI output can be standard TMDS-open-drain source, as well to be selected with internal source termina- tion as 50 ohm pull up to 3.3V VDD, using ROUT_SEL pin control or I2C control. When port 2 is active as DP to HDMP level shifter, the DDC channel can be selected between bi-direction DDC buffer and passive DDC switch in I2C mode. HPD1, HPD2 are with internal CMOS buffers and can support 3.3V and 5V HPD inputs. Squelch Mode Squelch function will disable HDMI data output (as high impedance)when the voltage and frequency of input clock (TMDS) are below squelch threshold, which will prevent random noise presenting in HDMI data output, thereby prevent noise on sink display. Squelch function will enable-resume HDMI data output when input clock signals are above squelch threshold. 15-0163 |
