1394b-2002 Revision 1.33+ at 1-Gigabit
Signaling Rates
• Fully Supports Provisions of IEEE Std
1394a-2000 and IEEE Std 1394-1995
Standards for High-Performance Serial Bus
• Fully Interoperable With Firewire™, i.LINK™,
and SB1394 Implementations of IEEE Std
1394
• Provides Two Fully Backward-Compatible,
IEEE Std 1394a-2000 Fully Compliant)
Bilingual IEEE Std 1394b-2002 Cable Ports at
up to 800 Megabits per Second (Mbps)
• Full IEEE Std 1394a-2000 Support Includes:
– Connection Debounce

– Multispeed Concatenation
– Arbitration Acceleration
– Fly-By Concatenation
– Port Disable/Suspend/Resume
• Extended Resume Signaling for Compatibility
With Legacy DV Devices
• Power-Down Features to Conserve Energy in
Battery-Powered Applications
• Low-Power Sleep Mode
• Fully Compliant With Open Host Controller
Interface (OHCI) Requirements
• Cable Power Presence Monitoring
• Cable Ports Monitor Line Conditions for
Active Connection to Remote Node
• Register Bits Give Software Control of
Contender Bit, Power-Class Bits, Link Active
Control Bit, and IEEE Std 1394a-2000
Features
• Interoperable With Other 1394 Physical
Layers (Phy) Using 1.8-V, 3.3-V, and 5-V
Supplies
• Low-Jitter, External Crystal Oscillator
Provides Transmit and Receive Data at
100/200/400/800 Mbps and Link-Layer
Controller Clock at 49.152 MHz and 98.304
MHz
• Separate Bias (TPBIAS) for Each Port
• Software Device Reset (SWR)
• Fail-Safe Circuitry Senses Sudden Loss of
Power to the Device and Disables the Ports
Ensure That the TSB83AA22A Does Not Load
the TPBIAS of Any Connected Device and
Blocks any Leakage From the Port Back to
Power Plane.
• The TSB83AA22A Has an IEEE Std
1394a-2000-Compliant Common-Mode Noise
Filter on Incoming Bias Detect Circuit to Filter
Out Cross-Talk Noise.
• The TSB83AA22A Is Port Programmable to
Force IEEE Std 1394a-2000 Mode to Allow
Use of IEEE Std 1394a-2000 Connectors
(IEEE Std 1394b-2002 Signaling Must Not Be
Put Across IEEE Std 1394a-2000 Connectors
or Cables).
• 3.3-V and 5-V PCI Signaling Environments
• Serial-Bus Data Rates of 100 Mbps, 200
Mbps, 400 Mbps, and 800 Mbps
• Physical Write Posting of up to Three
Outstanding Transactions
• Serial ROM or Boot ROM Interface Supports
2-wire Serial EEPROM Devices
• 33-MHz/32-Bit PCI Interface
• Multifunction Terminal (MFUNC Terminal 1):
– PCI_CLKRUN Protocol per the PCI Mobile
Design Guide
– General-Purpose I/O
– CYCLEIN/CYCLEOUT for External Cycle
Timer Control for Customized
Synchronization
