Serial Transmitter
The serialtransmitter 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 serialreceiver is aserial-to-parallel data converter. The
serial-to-parallelconverter 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-positionr ight-anglereceptacle assembly interfaces the

High Speed Serial Data Connector (HSSDC) Cable
The HSSDC 8-position cable assembly is the copper medium through
whichthe serial data is transferred.
MXI-3 Cable Options
Cablesare available for both the copper and fiber-opti c versions of MXI-3.
Copperlinks are the least expensive interconnectand can span up to
10 meters between systems. Fiber optic links offer connections
between systems separated by up to 200 meterswithout repeaters.
NationalI nstrumentsoffers 2 meter,5 meter, and 10 meter copper
cables and a 30 meterfiber optic cable as described in Table 3-1.
