A 10 Gb/s bit interleaving CDR for low-power PON

A novel, low power, downstream clock and data recovery (CDR)- decimator architecture is proposed for next generation, energy efficient 10 Gb/s optical network units (ONUs). The architecture employs a new time division multiplexing (TDM) bit-interleaving downstream concept for passive optical networks (Bi-PON) allowing early decimation of the incoming data and lowering of the processing speed to the user rate of the ONU, thus reducing the power consumption is significantly.
