1.1 Brief Description
The EV8000 Evaluation Kit comprises two boards. The signalling processor board contains an
FX828 and an FX829. 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 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 µC 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
signalling processor board C-BUS. The EV8000 is controlled by Windows^TM software on the PC.
