LinkMD Cable Diagnostics
The KSZ8842M LinkMD uses time domain reflectometry (TDR) to analyze the cabling plant for common cabling problems
such as open circuits, short circuits, and impedance mismatches.
LinkMD works by sending a pulse of known amplitude and duration down the MDI and MDI-X pairs and then analyzes the
shape of the reflected signal. Timing the pulse duration gives an indication of the distance to the cabling fault with a
maximum distance of 200m and an accuracy of +/–2m. Internal circuitry displays the TDR information in a user-readable
digital format in registers P1VCT[8:0] or P2VCT[8:0].
Note: cable diagnostics are only valid for copper connections –fiber-optic operation is not supported.
Access
LinkMD is initiated by accessing register P1VCT/P2VCT, the LinkMD Control/Status register, in conjunction with register
P1CR4/P2CR4, the 100BASE-TX PHY Controller register.
