IEEE1394A 2 PORT PHY I/O Controller Interface IC

nxp Inventar

Hauptmerkmale

  • Fully supports provisions of IEEE 1394–1995 Standard for high performance serial bus and the P1394a–2000 Standard.1
  • Fully interoperable with Firewire and i.LINK implementations of the IEEE 1394 Standard.2
  • Full P1394a support includes:
  • – Connection debounce
  • – Arbitrated short reset
  • – Multispeed concatenation
  • – Arbitration acceleration
  • – Fly-by concatenation
  • – Port disable/suspend/resume
  • Provides two 1394a fully-compliant cable ports at 100/200/400 Mbps.
  • Fully compliant with Open HCI requirements
  • Interface to link-layer controller supports both low-cost bus-holder isolation and optional Annex J electrical isolation
  • Supports extended bias-handshake time for enhanced interoperability with camcorders
  • Data interface to link-layer controller through 2/4/8 parallel lines at 49.152 MHz
  • Register bits give software control of contender bit, power class bits, link active bit, and 1394a features
  • Cable ports monitor line conditions for active connection to remote node.
  • Separate cable bias (TPBIAS) for each port
  • Logic performs system initialization and arbitration functions
  • Encode and decode functions included for data-strobe bit level encoding
  • Incoming data resynchronized to local clock
  • Single 3.3 volt supply operation
  • Minimum VDD of 2.7 V for end-of-wire power-consuming devices
  • Interoperable with link-layer controllers using 3.3 V and 5 V supplies
  • Interoperable with other Physical Layers (PHYs) using 3.3 V and 5 V supplies
  • Node power class information signaling for system power management
  • Cable power presence monitoring
  • Power down features to conserve energy in battery-powered applications include:
  • – Automatic device power down during suspend
  • – Device power down terminal
  • – Link interface disable via LPS
  • – Inactive ports powered-down
  • While unpowered and connected to the bus, will not drive TPBIAS on a connected port, even if receiving incoming bias voltage on that port
  • Can be used as a one port PHY without the use of any extra external components
  • Low-cost 24.576 MHz crystal provides transmit, receive data at 100/200/400 Mbps, and link-layer controller clock at 49.152 MHz
  • Does not require external filter capacitors for PLL
  • LQFP package is function and pin compatible with the Texas Instruments TSB41LV02AE and TSB41AB2E 400 Mbps PHYs.
