TSB81BA3PFP (TEXAS INSTRUMENTS)

The TSB81BA3PFP is a Digital and Analogue Transceiver functions needed 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, for packet reception and transmission. It is designed to interface with a link-layer controller (LLC), such as the TSB82AA2, TSB12LV21, TSB12LV26, TSB12LV32, TSB42AA4, TSB42AB4, TSB12LV01B or TSB12LV01C. It may also be connected cable port to cable port to an integrated 1394 Link + PHY layer such as the TSB43AB2. It is powered by dual supplies, a 3.3V supply for I/O and a core voltage supply. The core voltage supply is supplied to the PLLVDD-CORE and DVDD-CORE terminals to the requirements in the recommended operating conditions. It requires an external 98.304MHz crystal oscillator to generate a reference clock.
