1. A high-speed data transmission interface circuit, used in a network switch device, comprising:
a main circuit board, comprising:
a transmission port interface module, further comprising a reduced pin extended attachment unit interface (RXAUI); anda first wire, wherein a first impedance of the first wire is ±10% of 100 ohms; a connector, connected to the main circuit board through the first wire, wherein an insertion loss range of the connector at a working frequency of at least 3.125 GHz is smaller than or equal to 0.2 dB and more than 0 dB; and a daughter circuit board, comprising:
a high definition multimedia interface (HDMI) module, connected to an external network device by a HDMI signal wire, wherein the external network device is different from the main circuit board and the daughter circuit board; anda second wire, used to connect the connector and the HDMI module, wherein a second impedance of the second wire is ±10% of 100 ohms, wherein a material loss tangent of each element on the daughter circuit board is smaller than a material loss tangent of each element on the main circuit board; wherein by the first wire, the transmission port interface module outputs an output data to the external network device and receives an input data from the external network device through the connector, the second wire of the daughter circuit board and the HDMI module. |
