Advanced Micro Devices Inc, Sunnyvale – and Woking, Surrey in the UK – is sampling parts enabling its Supernet FDDI chip set to support FDDI over unshielded twisted pair cabling. To achieve this, it has developed a re-engineered Physical Layer Controller, and an MLT-3 transceiver, both of which it says are conformant with ANSI’s X3T9.5 committee’s standards. It adds that existing users of the chip set can easily adapt their designs to support FDDI over unshielded twisted pair. Companies planning to announce products based on Advanced Micro’s chip set include Crescendo Communications Inc, Eagle Technology Inc, Madge NV and IBM Corp. The Physical Layer Controller costs UKP14.10 in quantities of 1,000-up.
