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.
2. FEATURES
Complies with the IEEE 1394-1995 and IEEE 1394a-
2000 standards.
Supports transmission speeds of S400 (393.216 Mbit/
sec), S200 (196.608 Mbit/sec), and S100 (98.304
Mbit/sec).
Incorporates a 400-MHz PLL for transmission at
S400/S200/S100 and 50-MHz SCLK output.
Offers independent TpBias output for each port.
Supports the Cable Power Status function that detects
a cable power drop.
Supports DC and AC connections of the PHY/LINK
interface.
Built-in oscillating circuit
High-accuracy, low-amplitude differential high-speed
transceiver
Bus initialization, arbitration, port connection, and
control state machine circuits
PHY/LINK interface circuit
High-speed DS encoder
Supports the short bus reset function at detection of
LINK layer IC power-off.
Single 3.3-V power supply
64-Pin Plastic QFP
Designed with the low-power CMOS technology.
* This product is not radioresistant.
