description

The TSB11LV01 provides the analog transceiver functions needed to implement a single port node in a cable

based IEEE 1394-1995 network. The 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 TSB11LV01 is designed to interface with a link layer

controller, such as the TSB12C01A.

The TSB11LV01 requires an external 24.576-MHz crystal, which drives an internal phase-locked loop (PLL)

generating the required 98.304-MHz reference signal. The 98.304-MHz reference signal is internally divided

to provide the 49.152-MHz ±100 ppm system 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 link for

synchronization of the two chips and is used for resynchronization of the received data. The power-down

function, when enabled by asserting the PWRDN terminal high, stops operation of the PLL.

Data bits to be transmitted are received from the link on two parallel paths and are latched internally in the

TSB11LV01 in synchronization with the 49.152-MHz system clock. These bits are combined serially, encoded,

and transmitted at 98.304-Mbits/s as the outbound data-strobe information stream. During transmit, the

encoded data information is transmitted differentially on the TPB cable pair, and the encoded strobe information

is transmitted differentially on the TPA cable pair.

NOTE

In this document, phy is the physical layer and link is the link layer controller.
