1.2 Host Interface Connector
The BCM957508-P2100G NIC is a PCI Express 4.0 x16 add-in card with standard-height bracket. The card edge connector complies with the PCI Express 4.0 x16 standard pinout for add-in cards.
1.3 BCM57508 Ethernet Controller
The BCM57508 Ethernet controller is configured as dual-port 100 Gb/s interface to the line side and x16 PCI Express v4.0 interface to the system host.
1.4 PCI Express Interface
PCIe is a high-bandwidth serial bus providing a low pin-count interface as an alternative to parallel PCI. It is part of the host interface connector. The BCM57508 complies with the PCI Express Base Specification Revision 4.0, and supports an 16lane PCIe 4.0 interface via the host interface connector.
1.5 SMBus Interface
The BCM57508 Ethernet Controller SMB0 interface supports serial communications between BCM57508 and the system.
The interface allows the Ethernet controller to act as an SMBus master or a slave device.
1.6 Non-Volatile RAM
The BCM57508 Ethernet controller requires a non-volatile serial flash memory (NVRAM) to store the device firmware, PCI configuration space settings (for example, device ID, vendor ID), MAC address, and so on. After power-up, the firmware is downloaded into the device memory and executed by the on-chip processor.
1.7 Heat Sink
The passive heat sink is attached to the Ethernet controller using four spring-loaded push pins that insert into four mounting holes.
1.8 Power Supplies
All power is derived from the network adapter card host interface connector 12V and 3.3V supply which feeds the on-board regulators that provide the necessary power to the various components on the card. The network adapter card has six switching voltage regulators that power the card’s VDDC_AON, VDDC_HOST, +0.8V, +1.2V, +1.8V, and +3.3V loads.
1.9 QSFP56 Connector
The BCM957508-P2100G integrates two QSFP56 connectors to support 50G PAM-4 or 25G NRZ signaling for 100 Gb/s on each port. QSFP56 is backward compatible to QSFP28 and QSFP+ when appropriate cables and transceivers are used.
