Brief Description

The EV6020 Evaluation Kit comprises a single board containing an FX602 and its associated line

interface components. It communicates with the CML

µC board (EV6000), or the user's own µC

board, which can demonstrate the use of the FX602 in telecommunications applications, when user

programmed. The EV6020 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 (ZP,

MODE, IRQN and DET) and the FX602 may be driven from an external clock, or from its own crystal

oscillator. Important signals can be monitored by test points. The FX602 is socketed for easy

replacement; a ZIF socket may also be fitted. A user prototyping area is provided.

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 voice communications. A mutable voice input

and a

µC controllable or pre-settable DTMF generator are provided for CLI/CIDCW applications.

Operation of both these and the relays are indicated by LEDs. The parallel phone detector may be

used in adjunct box emulation. The FX602 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.

Finally, with a different jumper configuration, an FX604 and appropriate

µC firmware, the EV6020

board may be used for evaluating the FX604 or the FX614. The manual is enclosed on disk.
