Remember to maintain the same positions on the PCB layout so that you can implement these connections with the minimum length of routing and avoid possible signal integrity issues. Always consider the manufacturer's recommendations for routing digital interfaces like HDMI.
After implementing these changes on the schematic, it's always essential to ensure that your circuit still behaves as expected by simulating your design.

Based on the specifications of J2 (an HDMI connector) and U1 (CM2020-00TR, an HDMI Transmitter Port Protection and Interface device), here's how you could connect these two in your circuit to fulfill the standard HDMI interface:
  1. Connect J2:TMDS Data 2+ to U1:TMDS_D2+
  2. Connect J2:TMDS Data 2- to U1:TMDS_D2-
  3. Connect J2:TMDS Data 1+ to U1:TMDS_D1+
  4. Connect J2:TMDS Data 1- to U1:TMDS_D1-
  5. Connect J2:TMDS Data 0+ to U1:TMDS_D0+
  6. Connect J2:TMDS Data 0- to U1:TMDS_D0-
  7. Connect J2:TMDS Clock+ to U1:TMDS_CK+
  8. Connect J2:TMDS Clock- to U1:TMDS_CK-
  9. Connect J2:CEC to U1:CE_REMOTE_IN
  10. Connect J2:DDC Clock to U1:DDC_CLK_IN
  11. Connect J2:DDC Data to U1:DDC_DAT_IN
  12. Connect J2:Hot Plug Detect to U1:HOTPLUG_DET_IN
  13. Connect J2:+5V Power to U1:5V_SUPPLY
  14. Connect J2:Ground to U1:GND
  15. Connect U1's corresponding output pins to their counterparts in the HDMI Receiver end.
For the detailed connections relating to U1's specific operations like ESD protection, level shifting, and overcurrent output protection, please refer to the datasheet or application note of U1. Also, always ensure the grounds of all devices are also connected together when creating your circuit.
Please note that this connection scheme is based on typical applications and the pins of the components mentioned above. Depending on your specific use case and the other components in your circuit, you might need additional components or a different connection setup.

@copilot can you connect J1 to IC1 for me?
2y

copilot

Sure, I can guide you. But before we proceed, could you please confirm the specific pins you want to connect from J1 (USB-C Receptacle) to IC1 (CP2102N-A02-GQFN28)?
Here's a general guidance based on the common connections for these two types of components:
  • J1's D- to IC1's D-
  • J1's D+ to IC1's D+
  • J1's GND to IC1's GND
  • J1's VBUS to IC1's VDD
Do you want to follow these connections or do you have a specific connection in mind?

can you connect U2 and U3?
markwuflux

markwuflux

@copilot can you connect U2 and U3?
2y

copilot

Sure, but I'll need you to specify the interface or the pins you want to connect between U2 (ATMEGA328P-AU) and U3 (MAX7219EWG+).
For instance, if you want to connect U2 to U3 via SPI interface, typically three lines (MISO - Master In Slave Out, MOSI - Master Out Slave In, and SCK - Serial Clock) are needed for communication. Let's say you want to connect according to the following:
  1. ATMEGA328P-AU (U2) - MAX7219EWG+ (U3)
  2. MOSI (PB3 of U2) - DIN (1 of U3)
  3. SCK (PB5 of U2) - CLK (13 of U3)
  4. CS (PB2 of U2) - LOAD (12 of U3)
This would establish an SPI communication line. However, this is a general SPI connection. Please, provide specific interface or pins you want to connect.

can you suggest a part to add TVS protection to my USB bus?
markwuflux

@copilot can you suggest a part to add TVS protection to my USB bus?
2y

copilot

Sure, I suggest using a TVS diode for USB 2.0 protection. A suitable example would be Littlefuse's SMF05C.TCT.
This is a low-capacitance TVS diode array designed for protection of 5V USB ports. It provides protection for four data or interface lines in a small SOT23 configuration.
You can connect the TVS diode as follows:
  • The Vcc pin (pin 5) of the TVS diode should be connected to the VBUS net (J1:VBUS from USB connector).
  • The GND pin (pin 2) of the TVS diode should be connected to the Ground grid.
  • The I/O pins (pins 1, 3, 4 and 6) of the TVS diode should be connected to the D+ and D- lines respectively.
Please be aware that you might need to create a footprint for this part if it doesn't exist in your current library. Also, always check the datasheet for particular connection information, and validation of its compatibility with your current circuit. If SMF05C.TCT is not available, similar parts from other manufacturers can also be used as long as they meets your specification.
