BCM84784数据手册Broadcom中文资料规格书

描述 Description

Dual 40-Gigabit Ethernet (GbE) PPI-to-XLAUI (40-Gigabit electrical interface) PHY that incorporates an electronic dispersion compensation (EDC) equalizer supporting SR4, LR4 and copper CR4 line-card applications. The BCM84784 is a multirate PHY targeted for QSFP+ modules. The BCM84784 is fully compliant with the 40-GbE SR4, LR4 and copper CR4 standards and also supports backward-compatible 8-by-10/1 GbE per lane, per the IEEE 802.3ae.

特性 Features

·Each of the two 40G ports also has a 4 x 10G mode
·Dual 40G XLPPI-to-XLAUI/quad-channel 10-GbE PHY developed in low-power 40 nm CMOS process technology
·10-GbE IEEE 1588 timestamping, as well as Y.1731 with Sync-E recovered clock outputs, in 4 x 10G mode
·Supports 40G SR4, LR4 and copper CR4
·Low latency design, ~ 50 ns
