Enhanced Diminishing Manufacturing Sources (DMS) Support
Enhanced Product-Change Notification
Qualification Pedigree
Fully Supports Provisions of IEEE P1394b Revision 1.33+ at 1-Gigabit Signaling Rates
Fully Supports Provisions of IEEE 1394a-2000 and 1394-1995 Standard for High Performance Serial Bus
Fully Interoperable With Firewire., i.LINK., and SB1394., Implementation of IEEE Std 1394
Provides Three Fully Backward Compatible, (1394a-2000 Fully Compliant) Bilingual P1394b Cable Ports at up to 800 Megabits per Second (Mbits/s)
Provides Three 1394a-2000 Fully Compliant Cable Ports at 100/200/400 Mbits/s
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
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
Software Device Reset (SWR)
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
The TSB81BA3 Has a 1394a-2000 Compliant Common-Mode Noise Filter on the Incoming Bias Detect Circuit to Filter Out Cross-Talk Noise
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)
