TC3097-8: 8Ports Repeater Interface Controller
TC3097-8:LAN以太网芯片的详细介绍
general desc-ription:
the tc3097-8 lite end multiport repeater interface controller (lemric) may be used to implement an ieee 802.3 multiport repeater unit. it fully satisfies the ieee 802.3 repeater specification including the functions defined by the repeater, segment partition and jabber lockup protection state machines.
the lemric has an on-chip phase-locked-loop (pll) for manchester data decoding, a manchester encoder, and an elasticity buffer for preamble regeneration. in addition, it provides direct led display driver pins for per port link/rcv status, per port partition jabber status, global jam and jabber lockup status indications.
each lemric can connect up to 9 cable segments via its network interface ports. one port is fully attachment unit interface (aui) compatible and is able to connect to an external medium attachment unit (mau) using the maximum length of aui cable. the other 8 ports have integrated 10base-t transceivers. in addition, large repeater units may be constructed by cascading lemrics together over the inter-lemric bus.
features:
functionally conforms to ieee 802.3, section 9, specification
9 network connection(ports) per chip including:
1 aui port with fully compatible and drive capability (50m aui cable)
8 tp port with fully compatible and drive capability (100m tp cable)
cascadable for large multiple lemric hub applications
on-chip elasticity buffer, manchester encoder and decoder
separate partition state machine for each port
embeded led output driver for per port partition status, per port link/receive status(tp port), global jam status, and global jabber status. no external glue logic require
embedded predistortion resistors for every tp port.
build in power reset circuit, no extra glue logic required
crystal/oscillator optional applicable
manchester code violation detection and reporting
support mau jabber lockup protection function
support auto partition/reconnection function to isolate a faulty segment" s collision activity
fully integrated link test logic with enable/disable option, conforming to the 10base-t standard
fully integrated polarity detect/correct logic with enable/disable option for per tp port
low power consumption, fully load < 900 mw
cmos device feature high integration with a single + 5v supply
100-pin qfp package
