Shenzhen Mingjiada Electronics Co., Ltd. supplies and acquires Microchip Ethernet Transceiver VSC8491YJU-17 Ethernet IC 10 GbE Phy Single Port

Description: VSC8491YJU-17

The VSC8491YJU-17 device is a 10G/1G WAN/LAN/Backplane RXAUI/XAUI to SFP+/KR 10 GbE SerDes PHY with VeriTime™ and Intellisec™. It supports IEEE 802.1AE, IEEE 802.3ae and IEEE 1588v2.

The VSC8491YJU-17 is an IEEE 1588v2 compliant device for timing critical applications. It is also well suited for optical modules, copper Twinax cables, and backplane applications, and supports a variety of protocols, including 10 GbE LAN, 10 Gb WAN, and 1 Gb legacy Ethernet.

The VSC8491YJU-17 device provides seamless integration between IEEE 1588v2 and the MACsec engine without compromising on accuracy.The MACsec function of the VSC8491-17 device supports the IEEE 802.1AE 128/256-bit MACsec protocol, which meets the security requirements for securing data traversing Ethernet LANs, such as input classification, frame encryption/decryption, performance, and security. and frame encryption/decryption, performance and latency monitoring.
