FW803

Data Sheet, Rev. 3 June 2001 FW803 PHY IEEE * 1394A Three-Cable Transceiver/Arbiter Device Distinguishing Features I Compliant with IEEE P1394a Draft 2.0 Standard for a High Performance Serial Bus (Supplement) I Supports extended BIAS_HANDSHAKE time for enhanced interoperability with camcorders. I While unpowered and connected to the bus, will not drive TPBIAS on a connected port even if receiving incoming bias voltage on that port. I Does not require external filter capacitors for PLL. I Does not require a separate 5 V supply for 5 V link controller interoperability. I Interoperable across 1394 cable with 1394 physical layers (PHY) using 5 V supplies. I Interoperable with 1394 link-layer controllers using 5 V supplies. I Powerdown features to conserve energy in batterypowered applications include: — Device powerdown pin. — Link interface disable using LPS. — Inactive ports power down. I Interface to link-layer controller supports Annex J electrical isolation as well as bus-kee...
