TSB21LV03CMHV

Triple Port Cable Transceiver/Arbiter 6TX 6RX 200Mbps 68Pin CFPAK

description

The TSB21LV03C provides the analog and digital physical layer functions needed to implement a three-port node in a cable-based IEEE 1394-1995 network. Each cable port incorporates two differential line transceivers. The transceivers include circuitry to monitor the line conditions as needed for determining connection status, for initialization and arbitration, and for packet reception and transmission. The TSB21LV03C is designed to interface with a link-layer controller LLC, such as the TSB12LV21, TSB12LV31, TSB12C01, TSB12LV22, TSB12LV41, or TSB12LV01.
