description
The TSB21LV03B 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 TSB21LV03B is designed to
interface with a link-layer controller (LLC), such as the TSB12LV21A, TSB12LV31, or TSB12C01A.
The TSB21LV03B 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. For the TSB21LV03B, the 49.152 MHz clock output is active when RESET is asserted low. 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 TSB21LV03B supports an optional isolation barrier between itself and its LLC. When ISO is tied high, the
link interface outputs behave normally. Also, when ISO is tied high, the internal bus hold function is enabled for
use with the TI Bus Holder (patent pending) isolation. TI bus holder isolation is implemented when ISO is tied
high.
This serial bus implements technology covered by one or more patents of Apple Computer, Incorporated and INMOS, Limited.
