TSB81BA3, TSB81BA3I
IEEE 1394b THREEĆPORT CABLE TRANSCEIVER/ARBITER
SLLS559B − DECEMBER 2002 − REVISED OCTOBER 2003
D Fully Supports Provisions of IEEE P1394b
Revision 1.33+ at 1-Gigabit Signaling Rates
D Fully Supports Provisions of IEEE
1394a−2000 and 1394−1995 Standard for
High Performance Serial Bus
D Fully Interoperable With Firewire, i.LINK,
and SB1394, Implementation of IEEE Std
1394
D Provides Three Fully Backward
Compatible, (1394a−2000 Fully Compliant)
Bilingual P1394b Cable Ports at up to
800 Megabits per Second (Mbits/s)
D Provides Three 1394a−2000 Fully
Compliant Cable Ports at 100/200/400
Mbits/s
D Full 1394a−2000 Support Includes:
− Connection Debounce
− Arbitrated Short Reset
− Multispeed Concatenation
− Arbitration Acceleration
− Fly-By Concatenation
− Port Disable/Suspend/Resume
− Extended Resume Signaling for
Compatibility With Legacy DV Devices
D Power-Down Features to Conserve Energy
in Battery Powered Applications
D Low-Power Sleep Mode
D Fully Compliant With Open Host Controller
Interface (HCI) Requirements
D Cable Power Presence Monitoring
D Cable Ports Monitor Line Conditions for
Active Connection to Remote Node
D Register Bits Give Software Control of
Contender Bit, Power Class Bits, Link
Active Control Bit, and 1394a−2000
Features
D Data Interface to Link-Layer Controller Pin
Selectable From 1394a−2000 Mode (2/4/8
Parallel Bits at 49.152 MHz) or 1394b Mode
(8 Parallel Bits at 98.304 MHz)
D Interface to Link-Layer Controller Supports
Low Cost TI Bus-Holder Isolation
D Interoperable With Link-Layer Controllers
Using 3.3-V Supplies
D Interoperable With Other 1394 Physical
Layers (PHYs) Using 1.8-V, 3.3-V, and 5-V
Supplies
D Low Jitter, External Crystal Oscillator
Provides Transmit and Receive Data at
100/200/400/800 Mbits/s, and Link-Layer
Controller Clock at 49.152 MHz and
98.304 MHz
D Separate Bias (TPBIAS) for Each Port
D Low Cost, High Performance 80-Pin TQFP
(PFP) Thermally Enhanced Package
D Software Device Reset (SWR)
D Fail-Safe Circuitry Senses Sudden Loss of
Power to the Device and Disables the Ports
to Ensure That the TSB81BA3 Does Not
Load the TPBIAS of Any Connected Device
and Blocks any Leakage From the Port
Back to Power Plane
D The TSB81BA3 Has a 1394a−2000
Compliant Common-Mode Noise Filter on
the Incoming Bias Detect Circuit to Filter
Out Cross-Talk Noise
D The TSB81BA3 Is Port Programmable to
Force 1394a Mode to Allow Use of 1394a
Connectors (1394b Signalling Must Not Be
Put Across 1394a Connectors or Cables)
