Analog Devices Inc. ADN469xE M-LVDS 收发器

Analog Devices ADN469xE M-LVDS 收发器在所有多点低电压差分信号收发器中，所提供的ESD保护最高。ADI ADN469xE M-LVDS 系列共有8个收发器，均可通过单一差分对心缆线与32个数据/时钟节点进行连接，数据速率为 100Mbps或200 Mbps。相比之下，传统的LVDS通信链接必须使用 32个单独的点对点节点，使功耗、连接器规模、配线成本以及总板空间等均大幅提升。ADI ADN469xE 收发器可提供 8kV IEC ESD 保护，最高可达竞争性 M-LVDS 收发器的11倍。保护级别的提高，增强了无线基站和网络基础设施、数据采集、自动测试设备，以及其他高速、高度网络化的背板和电缆等应用场合中可插入/可拆卸板卡的可靠性。

ADI ADN469xE transceivers 8kV IEC ESD protection, offering up to 11 times the protection of competing M-LVDS transceivers. This higher level of protection improves the reliability of insertable/removable boards and cards used in wireless base station and networking infrastructure, data acquisition, automated test equipment, and other high-speed, highly networked backplane and cable applications.
