FW802
  • Low-Power PHY 1394a-2000 Two-Port Transceiver/Arbiter Devices
  • LSI FW802 devices provide the analog physical layer functions needed to implement a two-port node in a cable-based IEEE 1394-1995 and IEEE 1394a-2000 network.
  • Each cable port incorporates two differential line transceivers, including circuitry to monitor line conditions needed for determining connection status, initialization and arbitration, and packet reception and transmission.

Features

  • Available in the following package options:
    — 64-pin TQFP (lead-free)
    — 48-pin TQFP (lead-free)
    — 48-ball VTFSBGA (lead-free)
  • Compliant with IEEE® Standard 1394a-2000, IEEE Standard for a High Performance Serial Bus Amendment 1.
  • Supports extended BIAS_HANDSHAKE time for enhanced interoperability with camcorders.
  • While unpowered and connected to the bus, will not drive TPBIAS on a connected port even if receiving incoming bias voltage on that port.
  • Does not require external filter capacitors for PLL.
  • Does not require a separate 5 V supply for 5 V link controller interoperability.
  • Interoperable across 1394 cable with 1394 physical layers (PHY) using 5 V supplies.
  • Interoperable with 1394 link-layer controllers using 5 V supplies.
  • 1394a-2000 compliant common mode noise filter on incoming TPBIAS
  • Interface to link-layer controller supports Annex J electrical isolation as well as bus-keeper isolation.
  • Provides two compliant cable ports at 100 Mbits/s, 200 Mbits/s, and 400 Mbits/s.

Benefits

  • Powerdown features to conserve energy in battery powered applications include the following:
    — Device powerdown pin/ball
    — Link interface disable using LPS                                 — Inactive ports power down.                                           — Automatic micro-low-power sleep mode during 
         suspend
  • Low-power consumption during powerdown or microlow-power sleep mode.
  • Supports OHCI requirements.
  • Supports arbitrated short bus reset to improve utilization of the bus.
  • Compliant and interoperable with IEEE 1394 TA specification.
