The default input is DP in pin control mode and can be switched between DP or HDMI in I2C control mode. Pin control mode has only automatic port selection. I2C control mode has both automatic and manual 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 termination 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. 14-0150 5 www.pericom.com 09/26/14 PI3WVR31212 DP/HDMI 1:2 De-multiplexer switches Truth Table for TMDS port2 EQ – three level pin control PRE-EMP – three level pin control EQ Equalization value PRE_SEL TX pre-emphasis 0 1.5dB 0 0dB open 4.0dB open 1.5dB 1 6.5dB 1 2.5dB ROUT_SEL ROUT_SEL Pull-Up Resistors on port2 D[0:2]P2/N2, CLKP2/N2 0 No Pull-up resistors 1 50Ω Pull-up resistors to VDD 1 6.5dB Truth Table for AUX and DDC PORT When Port1 Selected DP/HDMI CAB_1 AUXP AUXN SCL SDA DP Mode 0 AUX1P AUX1N Hi-Z Hi-Z DP Mode 1 Hi-Z Hi-Z SCL1 SDA1 HDMI Mode x Hi-Z Hi-Z SCL1 SDA1 Priority Selection Table PRI_SEL (Priority order) HPD1 HPD2 HPD_SRC CAB_SRC AUXP/AUXN SDA/SCL 0 or 1 0 0 Hi-Z Hi-Z Hi-Z Hi-Z 0 or 1 1 x HPD1 CAB1 AUX1P/AUX1N SDA1/SCL1 0 or 1 0 1 HPD2 High Hi-Z SDA2/SCL2 M 0 0 Hi-Z Hi-Z Hi-Z Hi-Z M 1 0 HPD1 CAB1 AUX1P/AUX1N SDA1/SCL1 M x 1 HPD2 High Hi-Z SDA2/SCL2 Note: M=internal half VDD when input=HiZ PRI_SEL (Priority order) HPD1 HPD2 D0P D1P D2P D3P D0N D1N D2N D3N 0 or 1 0 0 Hi-Z Hi-Z Hi-Z Hi-Z Hi-Z Hi-Z Hi-Z Hi-Z 0 or 1 1 x D0P1 D1P1 D2P1 D3P1 D0N1 D1N1 D2N1 D3N1 0 or 1 0 1 D2P2 D1P2 D0P2 CLKP2 D2N2 D1N2 D0N2 CLKN2 M 0 0 Hi-Z Hi-Z Hi-Z Hi-Z Hi-Z Hi-Z Hi-Z Hi-Z M 1 0 D0P1 D1P1 D2P1 D3P1 D0N1 D1N1 D2N1 D3N1 M x 1 D2P2 D1P2 D0P2 CLKP2 D2N2 D1N2 D0N2 CLKN2 Note: M=internal half VDD when input=HiZ 14-0150 6 www.pericom.com 09/26/14 PI3WVR31212 DP/HDMI 1:2 De-multiplexer switches Maximum Ratings (Above which useful life may be impaired.
