64 pin LQFP package
2. General Description
The RTL8801 provides three-port physical layer(PHY) function in a cable-based IEEE 1394-1995
and IEEE P1394a 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.
Data bits to be transmitted through the cable ports are received from the Link on 2/4/8 data lines
(D0-D8), and are latched internally in the RTL8801 in synchronization with the 49.152 MHZ
system clock these bits are combined serially, encoded, and transmitted at 98.304 , 196.608 or
393.216Mbps as the outbound data-strobe information stream. During transmission, the encoded
data transmitted differential on the TPB cable pair(s), and the encoded strobe information is
