Optical transceiver and NE64

Hello,

has anybody connected an optical ethernet transceiver to a NE64?
I plan to use an Avago AFDR5903Z but the datasheet only shows a connection to LVPECL devices and is quite different from the Freescale schematics with standard transformer.

Any help welcome!

Thanks,
Bruno

Although the physical connection can be established with the adequate pull-up/pull-down arrays, it absolutely impossible to make it work because the MLT-3 encoding cannot be bypassed!
Freescale has forgotten this very subtle detail that would enable the NE to talk through optical.

I shall add an external TX/FX transcoder in my equipment.
