TSB41LV04APFP [Rochester]

The TSB41LV04A is a 4-port IEEE 1394a-compliant physical layer (PHY) device that enables node implementation in cable-based IEEE 1394 networks. It interfaces with link-layer controllers (LLCs) through 2/4/8 parallel lines at 49.152 MHz and supports 100/200/400 Mbits/s data rates. The device features P1394a compliance including suspend/resume, power-down modes, ultralow-power sleep mode, and cable power monitoring. It operates from a single 3.3-V supply and requires only an external 24.576 MHz crystal. The PHY supports TI bus-holder isolation and optional Annex J electrical isolation, and comes in a thermally enhanced 80-pin TQFP (PFP) package.
