description

The TSB21LV03 provides the analog 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

initializationandarbitration, andforpacketreceptionandtransmission. TheTSB21LV03isdesignedtointerface

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.
