DP83867IR: Sometimes the DP83867IR's synchronous ethernet failed to restore the receiving clock

user4197241

Part Number: DP83867IR

I use DP83867IR for synchronous Ethernet, the register configuration is ok. But in many cases, the receiving clock cannot be recovered from the network, and it needs to plug and unplug the network cable to recover the receiving clock.I don't know if anybody has had this problem?

The register configuration of DP83867IR is:

registers 0 : 0x9140

registers 32 : 0x0050

registers 170 : 0x0700

registers 134 : 0x0080

registers 172 : 0x0210

registers e9 : 0xdf22

registers 1f : 0x4000

Hello,

When you say many cases, what do you mean? Is the issue intermittent? Is your link going down as well when this happens?

Is your analog loopback working fine?

According to register 0x0032 setting to 0x0050 will disable RGMII interface, is this your intention? What mode and speed/duplex mode are you operating at?

Why is register 0x00E9 being configured? This is a reserved register.

Thanks,

Vibhu
