The EV6021 Evaluation Kit comprises a single board containing a CMX602B, line interface components, PIC Controller and the option of using either the on-board 4-line LCD module or interfacing to a PC via a serial communications port. For the latter mode of operation Windows software is supplied. When using the LCD module three switches are used to select the EV6021 mode of operation. The board is powered from a single 8 - 14V dc power supply; an on-board regulator sets VDD. LEDs indicate control, interrupt and detect line status (ZP, MODE, IRQN and DET) and the CMX602B may be driven from an external clock, or from its own crystal oscillator. Important signals can be monitored by test points. The CMX602B is socketed for easy replacement; there is room for the user to fit a ZIF socket. A user prototyping area is provided. |
