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 (HCI) 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 1394a-2000 Features
• 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)
• Interface to Link-Layer Controller Supports
Low Cost TI Bus-Holder Isolation
• Interoperable With Link-Layer Controllers
Using 3.3-V Supplies
• Interoperable With Other 1394 Physical Layers
(PHYs) 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
Mbits/s, and Link-Layer Controller Clock at
49.152 MHz and 98.304 MHz
• Separate Bias (TPBIAS) for Each Port
• Low Cost, High Performance 80-Pin TQFP
(PFP) Thermally Enhanced Package and
168-Pin ZAJ (BGA) Package
• Software Device Reset (SWR)
• Fail-Safe Circuitry Senses Sudden Loss of
Power to the Device and Disables the Ports to
Ensure That the TSB81BA3E Does Not Load
the TPBIAS of Any Connected Device and
Blocks any Leakage From the Port Back to
Power Plane
• The TSB81BA3E Has a 1394a-2000 Compliant
Common-Mode Noise Filter on the Incoming
Bias Detect Circuit to Filter Out Cross-Talk
Noise
• The TSB81BA3E Is Port Programmable to
Force 1394a Mode to Allow Use of 1394a
Connectors (1394b Signaling Must Not Be Put
Across 1394a Connectors or Cables)
• Internal Voltage Regulator Option
