HIGH-SPEED COMMUNICATION BOARDS
For high-speed emulator communication with a target (Section 2.4.2 “High-Speed
Communication”), use the following boards:
• High-Speed Driver Board
• High-Speed Receiver Board
7.7.1
The high-speed driver board consists of two separate multipoint LVDS (Low Voltage
Differential Signal) transmitters and receivers for clock and data. Multipoint LVDS
requires 100 ohm terminations at each driver output and receiver input, per the
standard, and multipoint configurations type 2 receivers are used, as these are
intended for control signals or where fail-safe provisions are needed. Even though the
standard allows for any combination of drivers, receivers and/or transceivers of up to
32 on the line, only two will be used. The driver board has a port expansion which is
controlled by an I
emulator. The high-speed driver board assembly is inserted into the emulator pod via
the card guide.
