Description

The TC3097 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.
