Realtek RTl8801
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.FEATURES
♦ Fully support provisions of IEEE1394-1995 for High- Performance Serial Bus and the P1394a draft 2.0 standard ♦ Provides three fully compliant cables ports at 100/200/400 Mbits/s and available with three ports ♦ Fully compliant with Open HCI requirements ♦ Full P1394a additional function support ♦ Support optional 1394 Annex J electrical isolation barrier at PHY-link interface ♦ Support power-down feature to conserve energy in battery–powered applications ♦ Cable power presence monitoring ♦ Separate cable bias (TPBIAS) and driver termination voltage supply for each port ♦ Encode and decode functions included for data-strobe bit level encoding ♦ Support LPS/link-on pin for PHY-link interface ♦ Incoming data resynchronized to local clock ♦ Single 24.576 MHZ crystal provide transmit/receive data at 100/200/400 Mbits/s and LLC clock at 49.152 MHZ ♦ Node power-class information signaling for system power management ♦ Adaptive equalizer ♦ Easy configured as a repeater ♦ Single 3.3V power supply ♦ 64 pin LQFP package 2.
