Other Parts Discussed in Thread: TLK105L

Hi,

I have a question about TLK105L Half duplex mode.

If MLED is routed to the COL(MLED)/PHYAD0(pin29),

I understood that collision functionality will be disable and can't use half duplex mode.

But in this case, do I must not to set the TLK105L to half duplex mode?

best regards,

Hi g.f.

If you want MLED to be functional on the COL pin, you must either be in Full-Duplex MII mode or in RMII mode Half or Full-Duplex.

You can use the AN_0 (LED_LINK) strap to force the link to only negotiate to Full-Duplex by adding a 2.2K ohm pull-up.

Regards,

Ross
