• Manufacturer Part Number: dp83222
• Description: Cyclone Twisted Pair Fddi Stream Cipher Device
• Manufacturer: National Semiconductor Corporation

All ECL signals require a standard ECL termination of 50X to V
Stream-Cipher Initialization refers to the algorithm employed by the Stream Cipher logic which by
processing the encoded datastream ultimately enters the Hold state allowing for synchronized
descrambling
