Serial Transmitter
The serial transmitter is a parallel-to-serial data converter. The
parallel-to-serial converter serializes the 20-bit wide parallel data
from the MXI-3 ASIC and sends it to the transceiver.
Serial Receiver
The serial receiver is a serial-to-parallel data converter. The
serial-to-parallel converter deserializes the data from the receiver and
supplies the 20-bit wide parallel data to the MXI-3 ASIC.
High Speed Serial Data Connector (HSSDC)
Receptacle
The HSSDC 8-position right-angle receptacle assembly interfaces the
electrical data to the copper serial cable.
High Speed Serial Data Connector (HSSDC) Cable
The HSSDC 8-position cable assembly is the copper medium through
which the serial data is transferred.
MXI-3 Cable Options
Cables are available for both the copper and fiber-optic versions of MXI-3.
Copper links are the least expensive interconnect and can span up to
10 meters between systems. Fiber optic links offer connections
between systems separated by up to 200 meters without repeaters.
National Instruments offers 2 meter, 5 meter, and 10 meter copper
cables and a 30 meter fiber optic cable as described in Table 3-1.
