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.
Gigabit Ethernet Link (Duplex SC Connector)
The Gigabit Ethernet Link Duplex SC Connector uses VCSEL technology
to convert electrical data into laser light, and transmits the data across a
fiber-optic cable. It also converts the laser light back to electrical data after
receiving it from the cable.
Gigabit Ethernet Link (Multi-Mode Fiber-Optic
Cable)
The Gigabit Ethernet Link Multi-Mode Fiber-Optic Cable is the medium
through which the laser light is transferred.
MXI-3 Cable Options
Both copper and fiber-optic cables are available for your MXI-3 system.
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.
