Cable Diagnostics
The KSZ8851SNL 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 register P1SCLMD[8:0].
Note: cable diagnostics are only valid for copper connections – fiber-optic operation is not supported.
Access
LinkMD
is initiated by accessing register P1SCLMD, the PHY special control/status and LinkMD register (0xF4).
