Notes:
1. GND is the symbol for signal and supply (power) common for the QSFP28 module. All are common within the module and all module voltages are referenced to this potential unless otherwise noted. Connect these directly to the host board signal common ground plane.
2. VccRx, Vcc1 and VccTx are the receiving and transmission power suppliers and shall be applied concurrently. Recommended host board power supply filtering is shown in Figure 3 below. VccRx, Vcc1 and VccTx may be internally
connected within the module in any combination. The connector pins are each rated for a maximum current of 1000mA.

Host Board Power Supply Filtering
Any voltage drop across a filter network on the host is counted against the host DC set
point accuracy specification. Inductors with DC Resistance of less than 0.1 Ohm should be used in order to maintain the required voltage at the Host Edge Card Connector. Figure is the suggested transceiver/host interface.
