When the cable is removed, leaving all mode pins uncon-
nected, the LTC2847/LTC2845 will enter no-cable mode.
In this mode the LTC2847/LTC2845 supply current drops
to less than 1000
μ
A and the LTC2847/LTC2845 driver
outputs are forced into a high impedance state. At the
same time, the R2 and R3 receivers of the LTC2847 are
differentially terminated with 103
and the other receiv-
ers on the LTC2847 and LTC2845 are terminated with
30k
to ground.
Cable Termination
Traditional implementations used expensive relays to
switch resistors or required the user to change termina-
tion modules every time a new interface standard was
