S400, and S400B Signaling Rates (B
Signifies 1394b Signaling)
Fully Supports Provisions of IEEE
1394a-2000 and 1394-1995 Standards for
High Performance Serial Bus
Fully Interoperable With Firewire
,
DTVLink
, SB1394
, DishWire
, and
i.LINK
Implementation of IEEE Std 1394
Provides Three Fully Backward
Compatible, (1394a-2000 Fully Compliant)
Bilingual 1394b Cable Ports at
400 Megabits per Second (Mbits/s)
Same Three Fully Backward Compatible
Ports Are 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 Automotive Sleep Mode
Support
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 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
(Eight Parallel Bits at 98.304 MHz)
Interface to Link-Layer Controller Supports
Low Cost Texas Instruments 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 Cost 49.152-MHz Crystal Provides
Transmit and Receive Data at
100/200/400 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 TSB41BA3A Does Not
Load the TPBIAS of Any Connected Device
and Blocks Any Leakage From the Port
Back to Power Plane
The TSB41BA3A Has a 1394a-2000
Compliant Common-Mode Noise Filter on
the Incoming Bias Detect Circuit to Filter
Out Cross-Talk Noise
Cable/Transceiver Hardware Speed and
Port Mode Are Selectable by Pin States
Supports Connection to CAT5 Cable
Transceiver by Allowing Ports to be Forced
to Beta-Only 100 Mbits/s only
Supports Connection to S200 Plastic
Optical Fiber Transceivers by Allowing
Ports to be Forced to 1394b Beta-Only
200 Mbits/s and S100 Mbits/s Only
Optical Signal Detect Input for All Ports in
Beta Mode Enables Connection to Optical
Transceivers
Supports Use of 1394a Connectors by
Allowing Ports 1 and 2 to Be Forced to
1394a-Only Mode
