BCM82756数据手册集成电路（IC）的电信规格书PDF

描述 Description

The Broadcom BCM82756 is a low-power, high-density PHY that integrates IEEE 802.1AE MACsec GCM-AES-256b encryption, IEEE 1588, retimer and EDC equalizer functions supporting 40GbE, 10GbE and 1GbE applications. The BCM82756 is targeted for SMF, MMF, or copper twin-axial applications interfacing to both limiting-based and linear-based SFP+, SFP and QSFP+ modules.
