Programmable Equalizer
The programmable equalizer module boosts the high frequency
components of the incoming signal to compensate for losses in the
transmission medium. There are five possible equalization settings (0, 1,
2, 3, 4) to compensate for 0”, 10”, 20”, 30”, and 40” of FR4 trace. These
settings should be interpreted loosely. The programmable equalizer can
be set dynamically or statically.
Receiver PLL & CRU
Each transceiver block has four receiver PLLs and CRUs, each of which is
dedicated to a receive channel. If the receive channel associated with a
particular receiver PLL or CRU is not used, then the receiver PLL or CRU
is powered down for the channel.
