3. 3 Copyright Quantum Parametrics LLC All Rights Reserved What is VersaPHY? VersaPHY is a 100% compatible extension to IEEE- 1394 VersaPHY is a 100% compatible extension to IEEE- 1394 VersaPHY devices coexist on the same 1394 network with any other 1394 devices VersaPHY devices coexist on the same 1394 network with any other 1394 devices VersaPHY extends the PHY layer and can be implemented with existing PHY silicon VersaPHY extends the PHY layer and can be implemented with existing PHY silicon NO new PHY silicon is needed NO new PHY silicon is needed VersaPHY provides PHY layer device identifiers and addressing (VP-Label) Allows communication with PHY devices Allows communication with PHY devices

4. 4 Copyright Quantum Parametrics LLC All Rights Reserved Why VersaPHY? The VersaPHY concept comes out of a need for lower cost and simpler 1394 implementations The VersaPHY accomplishes this by simplifying and in some cases eliminating device discovery after bus reset, providing a simple means for control and data delivery and a simple means for stream control

5. 5 Copyright Quantum Parametrics LLC All Rights Reserved What’s new with VersaPHY? To make this happen a few new 1394 facilities are defined. The new facilities are: Remotely and locally readable/writable PHY registers Extended and scalable PHY register map Read/write VersaPHY packets VersaPHY labels VersaPHY label management Note: The new facilities can be implemented using existing PHY silicon with external logic and/or software. No new PHY silicon is required however at some point it could be integrated to reduce costs and size further.

6. 6 Copyright Quantum Parametrics LLC All Rights Reserved Reduced Cabling! If we assume 1394 is being used for other purposes in the system (AV network) VersaPHY enables simple devices to connect to the 1394 bus at a minimal cost! If we assume 1394 is being used for other purposes in the system (AV network) VersaPHY enables simple devices to connect to the 1394 bus at a minimal cost! This reduces the number of cables and connectors, reducing cost and increasing reliability This reduces the number of cables and connectors, reducing cost and increasing reliability
