BCM957414M4142C Data Sheet Dual-Port 25 Gb/s SFP28 Ethernet PCI Express 3.0 x8 OCP 2.0 Mezzanine Card
3 Board Power and Environmental Specifications
Table 8 provides the adapter power consumption.
Table 9 provides the adapter environmental specifications. The system designer may deploy methods to monitor the
BCM57414 junction temperature (T
j
) and provide sufficient airflow for keeping T
j
below 105°C during normal operation. The
Broadcom AFBR-735SMZ active transceiver is recommended for the application.
