Other Parts Discussed in Thread: DP83869
We are planning to integrate the PHY chip DP83869HM with one of our controller with RGMII Interface MAC interface . Our basic requirement is to use the 1 Gbps Fiber optic . Our PCB will be having a single directional optical communication either Transmit or Receive . Please clarify below queries.
- Shall we use DP83869HM for the above described application?
- What is the interfacing standard for the SGMII for optical fiber ( CML or LVCMOS or LVDS )?If not CML, how can I convert it in to CML using terminations.
- In a single PCB either Tx channel or Rx channel will be present for the SGMII fiber optic interface. Does that cause any issue? or I can operate Tx & Rx only one at a time?
