1. DESCRIPTION
The SIR72900F00A is a physical layer IC compliant
with the IEEE 1394-1995 and IEEE 1394a-2000
standards.
With the two 1394 ports, the SIR72900F00A supports
transmission speeds of 400/200/100 Mbit/sec. The
product incorporates a 400-MHz PLL, reference voltage
generating circuit, high-speed transceiver, LINK layer
interface, and a state machine circuit for bus initialization
and arbitration.
