Other Parts Discussed in Thread: DP83869, , DP83869EVM
Hi,
We are planning to use the DP83869 PHY chip as a media converter chip.
Below are our hardware components and interfaces for full-duplex 100Mbps & 1Gbps ethernet communication:
RJ45(100BASE-TX/1000 BASE-T) <--> DP83869HM <--> MCU :RGMII <--> DP83869 : 100BASE-X/1000BASE-X <--> Optical transceiver module.
The Optical transceiver module has the following components:
---------------------------------------------------------------------------------------------------------------------------------------------
Transmit channel : TX_Differential_pair (from DP83869) --> Laser diode driver --> Laser Diode
Receive Channel : RX_Differential_pair (from DP83869) <-- Limiting Amplifier <-- TIA with Photo Diode
Additional signals from Optical transceiver module : LOS, Disable, Fault
---------------------------------------------------------------------------------------------------------------------------------------------
My questions:
1. Can I use DP83869HM for the above application?
2. Can I use available evaluation kit from TI for the above purpose?
3. Which signals does the MCU need from the DP83869 to determine the speed of RJ45?
Regards,
Yash
