Brief Description
The EV8000 Evaluation Kit comprises two boards. The signalling processor board contains an FX828
and an FX829. An FX818 is also provided and can be fitted in place of the FX828. The signalling
processor board is powered from a single 8 - 35V dc power supply; an on-board regulator sets 3.3V or
5.0V operation. LEDs indicate the status of the FX829 carrier detect output and the FX828
comparator output. Both of these lines are available on the same connectors as the C-BUS. The
FX828/818 and FX829 may be driven from a common external clock, or from a common crystal
oscillator. The supply current of either target device may be measured by removing the appropriate
jumper. A user prototyping area is provided and important signals can be monitored by test points.
There is an on-board microphone and a loudspeaker output.
C-BUS signals can be applied at either of two connectors (J1 or J2). The other can be used to add
future C-BUS evaluation kits in parallel with the EV8000. A third connector (J3) provides a daisy
chained C-BUS to enable a second EV8000 signalling processor board to be controlled from the same
PC. The signalling processor board can also be used with a user's own
µ
C board, with appropriate
software. Component footprints are provided in case the user requires level shifting between the C-
BUS input logic HI and the V
DD
level of the signalling processor board.
The µC board is fitted with a PIC µC containing the firmware to interface a PC serial port to the
TM
signalling processor board C-BUS. The EV8000 is controlled by Windows software on the PC.
