New Contributorcyclone v e LVDS
您好，我打算使用cyclone v e系列的5CEFA5芯片来设计pcb电路。我想将我的 fpga 与具有 1.8V 和 lvds 接口的 adc 连接，但我看到 lvds 仅支持 2.5v 电压输入。我可以将 vccio 设置为 1.8v 吗？或者这个 2.5v lvds 是否与 1.8v lvds 兼容？

Regular ContributorHello,
It should be compatible as long as you keep the Vid and Vicm is within the specification mentioned.
For optimized LVDS receiver performance, the receiver voltage input range must be within 1.0 V to 1.6 V for data rate above 700 Mbps and 0.00 V to 1.85 V for data rate below 700 Mbps.
2.5V only for powering up the differential input buffer.
