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 TSB21LV03 is designed to interface with a link-layer controller (LLC), such as the TSB12LV21, TSB12LV31, or TSB12C01A. The TSB21LV03 requires either an external 24.576-MHz crystal or crystal oscillator. The internal oscillator drives an internal phase-locked loop (PLL), which generates the required 196.608-MHz reference signal. The 196.608-MHz reference signal is internally divided to provide the 49.152/98.304-MHz clock signals that control transmission of the outbound encoded strobe and data information. The 49.152-MHz clock signal is also supplied to the associated LLC for synchronization of the two chips and is used for resynchronization of the received data. The power-down function, when enabled by taking the PD terminal high, stops operation of the PLL and disables all circuitry except the cable-not-active signal circuitry. The TSB21LV03 supports an optional isolation barrier between itself and its LLC. When ISO is tied high, the link interface outputs behave normally. When ISO is tied low, internal differentiating logic is enabled, and the outputs become short pulses, which can be coupled through a capacitor or transformer as described in the IEEE 1394-1995 Annex J. † This serial bus implements technology covered by one or more patents of Apple Computer, Incorporated and INMOS, Limited.
