Product Brief

FW801A/FW801BF

Low-Power PHY One-Cable Transceiver/Arbiter Devices

Video Server, and VTR Applications

F e a t u r e s

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.

Powerdown features to conserve energy

in battery powered applications include

the following:

— Device powerdown ball.

— Link interface disable using LPS.

— Inactive ports powerdown.

— Automatic micro-low-power sleep

Interface to link-layer controller supports

Annex J electrical isolation as well as bus-

keeper isolation.

Provides one fully compliant cable port at

100 Mbits/s, 200 Mbits/s, and 400 Mbits/s.

Fully supports 1394 Open HCI

requirements.

Supports arbitrated short bus reset to

improve utilization of the bus.

mode during suspend.

O t H e r F e a t u r e s

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® and

i.LINK® implementations of IEEE 1394-1995.

Reports cable power fail interrupt when

voltage at CPS ball falls below 7.5 V.

Provides separate cable bias and driver

termination voltage supply for port. Other

Features

48-pin TQFP and 48-ball VTFSBGAC

packages.

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

a 50 MHz link-layer controller clock as well

as transmit/receive data at 100 Mbits/s, 200

Mbits/s, and 400 Mbits/s.

Multiple separate package signals provided

for analog and digital supplies and grounds.

FW801 Functional Overview

The LSI FW801 devices provide

the analog physical layer functions

needed to implement a one-

port node in a cable-based IEEE

1394-1995 and IEEE 1394a-2000

network.

The cable port incorporates two

differential line transceivers. The

transceivers include circuitry

to monitor the line conditions

as needed for determining

connection status, for initialization

and arbitration, and for packet

reception and transmission. The

PHY is designed to interface with a

link-layer controller (LLC).
