D Data Interface to Link-Layer Controller
Through 2/4/8 Parallel Lines at 49.152 MHz
D Interface to Link Layer Controller Supports
Low-Cost TI Bus-Holder Isolation and
Optional Annex J Electrical Isolation
D Interoperable With Link-Layer Controllers
Using 3.3-V and 5-V Supplies
D Interoperable With Other Physical Layers
(PHYs) Using 3.3-V and 5-V Supplies
D Low-Cost 24.576-MHz Crystal Provides
Transmit Receive Data at 100/200/400
Mbits/s, and Link-Layer Controller Clock at
49.152 MHz.
D Separate Cable Bias (TPBIAS) for Each Port
D Single 3.3-V Supply Operation
D Low-Cost High Performance 80-Pin TQFP
(PFP) Thermally Enhanced Package
D Direct Drop-In Upgrade for
TSB41LV03APFP and TSB41LV03PFP
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 TSB41AB3 Does Not
Load the TPBIAS of Any Connected Device
and Blocks Any Leakage From the Port
Back to Power Plane.
D The TSB41AB3 Has a 1394a-Compliant
Common-Mode Noise Filter on the
Incoming Bias Detect Circuit to Filter Out
Crosstalk Noise.
