Cable
Measurement
Capability
These bits can be used as a cable length indicator. The bits are
incremented from 0000 to 1111, with an increment of
approximately 10 meters. The equivalent is 0 to 32 dB with an
increment of 2 dB @ 100 MHz. The value is a read back from
the equalizer, and the measured value is not absolute.
