FW802A

Data Sheet, Rev. 3 June 2001 FW802A Low-Power PHY IEEE* 1394A-2000 Two-Cable Transceiver/Arbiter Device Distinguishing Features I Compliant with IEEE Standard 1394a-2000, IEEE Standard for a High Performance Serial Bus Amendment 1. I Low-power consumption during powerdown or microlow-power sleep mode. 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 1394a-2000 compliant common mode noise filter on incoming TPBIAS. I Powerdown features to conserve energy in batterypowered applications include: — Device powerdown pin. ...
