Virtex-II Pro RocketIO - What is the termination set to before power is applied, after power is applied (before configuration), and after configuration?

描述

What is the RocketIO transceiver termination set to before power is applied, after power is applied (before configuration), and after configuration?

解决方案

Unpowered: set to 75 ohms.

Powered, not configured, or during configuration: set to 50 ohms.

During configuration: TXP/TXN does not drive; the outputs remain at VTTX (through 50 ohm termination).
