Broadcom Dual 800G MACsec/IPsec Retimer PHY - BCM85344
The Broadcom BCM85344 is a 5-nm low-power, high-density PHY integrating IEEE 802.1AE MACSec GCM-AES-256b encryption, IPSec, IEEE 1588, retimer, reverse gearbox and equalizer functions supporting 800-Gigabit Ethernet (800GbE), 400GbE, 200GbE, 100GbE, 50GbE, 40GbE and 25GbE applications. BCM85344 is designed to support CDAUI8, CDAUI4 electrical interfaces for QSFP-DD and OSFP optical modules.
The BCM85344 is designed in 5-nm CMOS technology to provide a low-power solution.
- Support 25G/40G/50G/100G/200G/400G/800G Ethernet applications
- Support 800GbE ports with CDAUI8-to-CDAUI8 interface for QSFP-DD, OSFP retiming/MACSec/IPSec encryption applications
- Support 400GbE ports with CDAUI8-to-CDAUI8 interface for QSFP-DD, OSFP retiming/MACSec/IPSec encryption applications
- Support 200GbE ports with CDAUI4-to-CDAUI4 for QSFP56 retiming/MACSec/IPSec encryption applications
- Support MACSec & IPSec in reverse gearbox modes
- Support IEEE 1588 to enable Class-D systems to meet stringent 5G timing requirements as well as ITU-T Y.1731 with Synchronous Ethernet (SyncE) recovered clock outputs
- Support FEC for all data rates up to 800G
- 5-nm process node
Applications
