DESCRIPTION

I In 10BaseT mode, Manchester encoded data

is received via TPR+/TPR-. After timing re-

covery and decoding it is output to the con-

troller on RXD. TPR+/TPR- are connected to

the twisted-pair medium through a trans-

former and filter.

A 100Ω termination resistor is generally used

before the circuit connects to the receive sig-

nal lines, TPR+ and TPR- inputs. See Figure

2-5 for information on this design.

The 83C694D automatically corrects for a

misconnection of the + and - interface allow-

ing operation without having to correct the

wiring.
