The Hudson is a fully integrated, Variable Rate Digital Wrapper Framer/Deframer, Performance Monitor, and Forward Error Correction (FEC)
device supporting the Digital Wrapper transmission standards for OTU1, OTU2, ODU1, ODU2, OPU1, and OPU2 as specified in G.709. The
Hudson implements Performance Monitoring and overhead processing functions on the Digital Wrapper overhead bytes. In addition, the
device contains SONET/SDH Performance Monitoring to verify the validity of the SONET/SDH OC-192 client data. The device can operate
from a low rate of 6.25 MHz to a high rate of 693.483 MHz. Data entering and leaving the chip can be optionally deframed and framed,
descrambled and scrambled, and decoded and encoded with forward error correction information.
• Core logic runs on a 1.8 V power supply to reduce power con-
• Two independent 16-bit parallel LVDS input and output ports at
• Datapath options: Configurable as two completely independent
• Supports SONET OC-192 Performance Monitoring at the input of
• Supports G.709 “Interfaces for the optical transport network
• ON/OFF control of Reed-Solomon (255,239) FEC Encoding/
