... Mbps operation The HYC9088A Twisted Pair and Coaxial Compatible High Impedance Transceiver (HIT hybrid module that interfaces an ARCNET Local Area Network controller to one twisted pair or coaxial cable. The HIT interfaces directly with Standard Microsystems Corporation's ARCNET LAN controllers operating at 2.5 Mbps and connects to a variety of shielded and unshielded twisted pair or coaxial cables via an on-board transformer ...

... FUNCTIONAL DESCRIPTION The HYC9088A HIT integrates a host of discrete components into a hybrid module and provides the Local Area Network designer with space and cost savings as well as the enhanced reliability of a single component. Since the HIT is a high impedance transceiver, it does not disturb the characteristic impedance of the cable used to interconnect ARCNET nodes ...
