- The common-mode DC\non RX and TX lines must\nbe less than 2 V, but VL670\nhas up to 2.2 V DC at TX\nlines (RX lines are okay).\n\nThus, we need to block\nDC by C5 and C6, then\nuse R16 and R17 to re-\nbias the operating point\nto 0 V.\n\nC1/2/3/4 are always needed\nto block DC at the host. C5/6\nand R16/17 are only needed\nwhen common-mode DC is\ngreater than 2 V, like VL670.\n\nUse 0402 or smaller for\nR16/17 to minimize stub.
