TSB41AB3PFP

The TSB41AB3PFP is a Digital and Analogue Transceiver functions required to implement a three-port node in a cable-based IEEE 1394 network. Each cable port incorporates two differential line transceivers. The transceiver includes circuitry to monitor the line conditions as needed for determining connection status, for initialization and arbitration and for packet reception and transmission. The TSB41AB3 is designed to interface with a line layer controller (LLC), such as the TSB12LV21, TSB12LV22, TSB12LV23, TSB12LV26, TSB12LV31, TSB12LV41, TSB12LV42 or TSB12LV01A. The TSB41AB3 requires only an external 24.576MHz crystal as a reference. An external clock may be used instead of a crystal. An internal oscillator drives an internal phase-locked loop (PLL), which generates the required 393.216MHz reference signal. This reference signal is internally divided to provide the clock signals used to control transmission of the outbound encoded strobe and data information.
