General Description
The HYC9088 Twisted Pair and Coaxial Compatible High Impedance
Transceiver (HIT) is a 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. The network
topologies supported by the HIT are daisy chain, star, and
bus configurations.
During data transmission, the HIT converts the digital pulse
information provided by the LAN controller into analog signals
and drives them onto the cable. The transmitted signals are
filtered to eliminate undesirable frequencies. The receiver
section of the HYC9088 identifies dipulse signals on the cable
and converts them into TTL signals to be supplied to the LAN
controller.
The HIT supports ARCNET's Dipulse Encoding Scheme and is
100% compatible with all existing coax-based ARCNET networks.
This provides an ARCNET network designer with flexibility to
easily combine coax and twisted pair cabling.
