Auto EQ has 3 modes. EQ (Pin 40) can select one of the Auto EQ modes. This pin is internally biased to 50% of VDD33 (M = VDD/2). "1": Enable "0": Disable "M": Please refer to the Functional Truth table 35 NC (PI3DPX1202A1) NC Non connection pin. Internally Pull-up tied to 3.3V VDD. This pin does not bond- out to package. 1 VDD33 Power 3.3V power supply 2 NC NC Do Not Connect. Leave this pin floating. 3 OC1/I2C_ADDR Shared Shared pin. Pulled-up internally with 100 kΩ "I2C_ADDR": SMBus control address pin "OC1": Voltage Swing control bit 1 4 OP0/SCL_CTL Shared Shared pin. Internally pulled-up with 100 kΩ "SCL_CTL": SMBus Clock "OP0": Pre-emphasis control bit 1 5 OP1/SDA_CTL Shared Shared pin. Internally pulled-up with 100 kΩ "SDA_CTL" : SMBus Data "OP1" : Pre-emphasis control bit 0 6 VDD33 Power 3.3V power supply 7 CNTRL Input Primary Control Pin for Auto-configuration or Fine-tuning boost mode "0" : SMBus mode "M" : Aux listener mode (Default) "1" : Pin strap mode. 8 CAD_SRC Output Cable Adapter Detection pin from source side "0": no cable adapter; enable DP redriver mode with AUX listening and link training active "1": Installed cable adapter; enable TMDS redriver mode and disable AUX inter- ception 9 HPD_SRC Output Hot Plug detect pin to source-side. 3.3V CMOS output. Active High 10 CAD_SNK Input Cable detect pin from sink-side. 1MΩ pull-down resister must be connected for proper cable detection 11 HPD_SNK Input Hot Plug Detect pin from the sink-side. Internally 200 kΩ Pull-down. 12 VDD33 Power 3.3V power supply 13 OUT3N Output Main Link 3 data 100 Ω Differential negative output. 14 OUT3P Output Main Link 3 data 100 Ω Differential positive output 15 NC NC Do Not Connect 16 OUT2N Output Main Link 2 data 100 Ω Differential negative output 17 OUT2P Output Main Link 2 data 100 Ω Differential positive output 18 GND Ground Ground 19 OUT1N Output Main Link 1 data 100 Ω Differential negative output |
