The
Compatible High Impedance Transceiver (HIT) is
a hybrid module that interfaces an ARCNET Local
Area Network controller to one twisted pair or
coaxial cable.
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
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

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.
The HYC9088 is pin compatible with the HYC9058
High Impedance Transceiver and is pin compatible
with the HYC9068 LAN Driver with the addition of
a single terminating resistor.
