Description
The Agere Systems Inc. FW802A device provides the analog physical layer functions needed to implement a two-port node in a cable-based IEEE 1394-1995 and IEEE 1394a-2000 network.
Distinguishing Features
■ Compliant with IEEE Standard 1394a-2000, IEEE Standard for a High Performance Serial Bus Amendment 1.
■ Low-power consumption during powerdown or microlow-power sleep mode.
■ 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.
■ Powerdown features to conserve energy in batterypowered applications include:
— Device powerdown pin.
— Link interface disable using LPS.
— Inactive ports power down.
— Automatic microlow-power sleep mode during suspend.
■ Interface to link-layer controller supports Annex J electrical isolation as well as bus-keeper isolation.Features
■ Provides two fully compliant cable ports at 100 Mbits/s, 200 Mbits/s, and 400 Mbits/s.
■ Fully supports OHCI requirements.
■ Supports arbitrated short bus reset to improve utilization of the bus.
■ Supports ack-accelerated arbitration and fly-by concatenation.
■ Supports connection debounce.
■ Supports multispeed packet concatenation.
■ Supports PHY pinging and remote PHY access packets.
■ Fully supports suspend/resume.
■ Supports PHY-link interface initialization and reset.
■ Supports 1394a-2000 register set.
■ Supports LPS/link-on as a part of PHY-link interface.
■ Supports provisions of IEEE 1394-1995 Standard for a High Performance Serial Bus.
■ Fully interoperable with FireWire† implementation of IEEE 1394-1995.
■ Reports cable power fail interrupt when voltage at CPS pin falls below 7.5 V.
■ Separate cable bias and driver termination voltage supply for each port.
■ Meets Intel‡ Mobile Power Guideline 2000.Other Features
■ 64-pin TQFP package.
■ Single 3.3 V supply operation.
■ Data interface to link-layer controller provided through 2/4/8 parallel lines at 50 Mbits/s.
■ 25 MHz crystal oscillator and PLL provide transmit/ receive data at 100 Mbits/s, 200 Mbits/s, and 400 Mbits/s, and link-layer controller clock at 50 MHz.
■ Node power-class information signaling for system power management.
■ Multiple separate package signals provided for analog and digital supplies and grounds. -
