| Notes: 1. QSFP-DD uses common ground (GND) for all signals and supply (power). All the common within the QSFP-DD module and all module voltages are referenced to this potential unless otherwise noted. Connected theses directly to the host board signal common ground plane.2. VccRx, VccRx 1, Vcc1, Vcc2, VccTx, and VccTx 1 shall be applied concurrently. Requirements defined for the host side of the Host Card Edge Connector are listed in Table 4. VccRx, VccRx 1, Vcc1, Vcc2, VccTx, and VccTx 1 may be internally connected within the module in any combination. The connector Vcc pins are each rated for a maximum current of 1000mA. 3. All Vendor Specific, Reserved and No Connect pins may be terminated with 50 ohms to ground on the host. Pad 65 (No Connect) shall be left unconnected within the module. Vendor Specific and Reserved pads shall have an impedance than 10 kOhms and less than 100pF. |
