Brief Description

The EV6040 Evaluation Kit comprises a single board containing an FX604 and its associated line

interface components. It communicates with the CML mC board (EV6000), or the user's own mC

board, demonstrating the use of an FX604 in modem applications, when user programmed. The

EV6040 board is powered from a single 8 - 35V dc power supply; an on-board regulator sets 3.3V or

5.0V operation. LEDs indicate data, control and interrupt line status (DET, RDYN, RXEQ, M0 and M1)

and the FX604 may be driven from an external clock, or from its own crystal oscillator. Important

signals can be monitored by test points. The FX604 is socketed for easy replacement; a ZIF socket

may also be fitted. The FX614 may be substituted for Bell 202 modem applications.

On-board relays may be used to implement a wetting pulse, to place an ac or dc load on the line, and

to interface the line to a transformer/op-amp hybrid for modem communications. A mutable voice

input and a mC controllable or pre-settable DTMF generator are provided; operation of both these and

the relays are indicated by LEDs. The parallel phone detector may be used in adjunct box emulation.

The FX604 supply current may be measured by removing a jumper. Where components are telco-

specific (line impedance, line protection, ac-load, wetting pulse, etc.) space is provided for the user to

add appropriate components. A user prototyping area is provided.

Finally, with a different jumper configuration, an FX602 and appropriate mC firmware, the EV6040

board may be used for evaluating the FX602. The EV6020 manual is enclosed on disk.
