Receive Clock System
Receive Line Interface
For data input, three different data types are supported:
• Ternary coded signals received at multifunction ports RL1 and RL2 from a -34 dB
• Digital dual rail signals received at ports RDIP and RDIN. The dual rail interface is
• Unipolar data at port ROID received from a fibre optical interface. The optical interface
Long Haul Interface
The QuadFALC has an integrated short- and long- haul line interface, comprising a
receive equalization network and noise filtering.
