BCM89881中文资料100BASE-T1 /1000BASE-T1 Single-Port Automotive Ethernet Transceiver数据手册Broadcom规格书

描述 Description

The BCM89881 is a 100BASE-T1/1000BASE-T1 automotive Ethernet transceiver integrated into a single monolithic CMOS chip. The device performs all the physical layer (PHY) functions for 100BASE-T1 and 1000BASE-T1 encoded Ethernet packets over a single-pair of unshielded twisted-pair (UTP) cable. The BCM89881 is designed to meet automotive specifications for EMI/EMC, noise cancellation, and transmission jitter, providing consistent and reliable operation over a broad range of existing single twisted-pair automotive cable.

特性 Features

• Fully compliant with IEEE 802.3bp 1000BASE-T1 and IEEE 802.3bw 100BASE-T1
• Highly integrated including on-chip LPF, single-voltage rail
• Low-power consumption and support for different low-power modes
• Meets stringent Automotive EMC requirements over UTP
• BroadR-SecureTM capable
• AECQ-100 Qualified
• Fast link-up time suitable for time-sensitive applications
• PHY timestamp for IEEE1588 / 802.1AS
• Supports RGMII MAC interface
