Manchester encoding ic

[DStewert]

I was wondering if the NKM4201 manchester encoding / decoding ic's could be used to increase the reliability of say an IR optical communications link.
Any thoughts on this are welcome.

Rfin and rfout will do what you want with the same encoding as your chip

NKM2401 could potentially improve things but alternatively it could perhaps make things worse; I'm not even sure how one would set about trying to determine which it would be other than to try it.

Manchester coding is used to keep a transmitted signal at a net DC level to keep the RF receiver happy and similar already exists within a normal IR receiver due to its ~36kHz modulation so it might not gain anything and glitches which would be ignored by an IR receiver may cause the NKM2401 to see that as a corrupt packet.

Thanks for the replies.
