CML Semiconductor Products Evaluation Kit User Manual EV6020 UM6020/4 December 1996 1.0 Features • For FX602 Product Evaluation • User's Prototyping Area • Reconfigurable Board with • Space for Optional and Telco- Advance Information Interface to Optional µ C Board Specific Components • Parallel Phone Detector • Single Power Supply Operation • Easy Access to Test Points • On-Board Regulator 1.1 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. 1996 Consumer Microcircuits Limited Evaluation Kit User Manual for FX602 EV6020 CONTENTS Section Page 1.0 Features......................................................................................................1 1.1 Brief Description ........................................................................................1 1.2 Preliminary Information .............................................................................4 1.2.1 Laboratory Equipment ..................................................................4 1.2.2 Handling Precautions....................................................................4 1.2.3 Telephone Line Connection ..........................................................5 1.3 Quick Start..................................................................................................5 1.3.1 Setting-Up ....................................................................................5 1.3.2 Operation .....................................................................................5 1.4 Signal Lists.................................................................................................6 1.5 Circuit Schematics and Board Layouts ....................................................8 1.6 Detailed Description ................................................................................10 1.6.1 Hardware Description - Evaluation Board....................................10 1.7 Performance Specification ......................................................................12 1.7.1 Electrical Performance................................................................12 1996 Consumer Microcircuits Limited 2 UM6020/4 Evaluation Kit User Manual for FX602 EV6020 Figure 1 Block Diagram 1996 Consumer Microcircuits Limited 3 UM6020/4 Evaluation Kit User Manual for FX602 1.2 Preliminary Information 1.2.1 Laboratory Equipment EV6020 The following laboratory equipment is needed to use this evaluation kit: 1.2.1.1 8 - 35V DC Power Supply. 1.2.1.2 Telephone Line Simulator and Line Signal Generator. 1.2.1.3 A µC control board (such as a CML EV6000, which contains the PIC 16LC74JW (or similar) µC), together with firmware and a user interface. 1.2.2 Handling Precautions Like most evaluation kits, this product is designed for use in office and laboratory environments. The following practices will help ensure its proper operation. 1.2.2.1 Static Protection This product uses low power CMOS circuits which may be damaged by electrostatic discharge.

Users are advised to observe local statutory requirements which may apply to this product. 1996 Consumer Microcircuits Limited 4 UM6020/4 Evaluation Kit User Manual for FX602 1.3 EV6020 Quick Start This section provides instructions for users who wish to experiment immediately with the evaluation kit. A fuller description of the kit and its use appears later in this document. 1.3.1 Setting-Up THE EV6020 COMES PRE-CONFIGURED WITH AN FX602, SET FOR OPERATION AT 5.0V. The board should be interconnected to a suitable µC control board with a 20-way flat cable, as shown in the Block Diagram of Figure 1. If the EV6000 µC board is not used, then power will need to be applied separately to the EV6020 evaluation kit through connector J3. An RJ11 (US style) phone jack is provided for telephone line simulator connection. No board adjustments are required by the user, although a (≈ 600Ω) line termination will need to be fitted to R20 before the EV6020 kit can be used. Other, telco-specific, components may be added, as required. BEFORE APPLYING POWER, PLEASE CHECK THE FOLLOWING: When using the EV6020 board with the EV6000 µC board, it will be noted that each board has connections for a single 8 - 35V dc power supply. Only one board needs to be connected as power is supplied to the other board over the flat cable. Each board has its own power supply regulator chip, with a jumper to select 3.3V or 5.0V (default ) operation. MAKE SURE BOTH BOARDS HAVE THIS JUMPER SET TO THE SAME VOLTAGE. DAMAGE MAY RESULT IF THIS STEP IS NOT OBSERVED. DO NOT OPERATE EITHER BOARD WITH ITS VOLTAGE SELECTION JUMPER REMOVED. Ensure the component value jumpers on the evaluation board are correctly set for 3.3V or 5.0V operation. Please refer to Section 1.6.1.5 for further details. 1.3.2 Operation This evaluation kit has no inherent functionality without a µC control board and appropriate firmware. The evaluation board may be used independently of the µC board, if the user wishes to interface to a different type of µC. 1996 Consumer Microcircuits Limited 5 UM6020/4 Evaluation Kit User Manual for FX602 1.4 EV6020 Signal Lists CONNECTOR PINOUT - EVALUATION BOARD Connector Ref.

These components are not fitted, but suitable values for UK applications are suggested in brackets. Wire links which bypass R27 and R28 will need to be cut if these resistors are fitted. 1.6.1.2 AC or DC Load An ac or dc load is provided by R30 (827Ω), R36 (1386Ω) and C10 (139nF). These components are not fitted, but suitable values for UK applications are suggested in brackets. This load is controlled by relay RLY3. A logic '1' on AC-LOAD (J1 pin 6) connects this load and illuminates the LED. 1.6.1.3 Wetting Pulse A wetting pulse load is provided by R26, which is not fitted. For UK applications, a suitable value may be in the region of 240Ω to 350Ω. The wetting pulse is controlled by relay RLY2. A logic '1' on WETTING PULSE (J1 pin 7) connects the wetting pulse load and illuminates the LED. 1.6.1.4 Transformer and Op-Amp Hybrid The transformer and op-amp hybrid are connected to the phone jack by relay RLY1. A logic '1' on TXLINE (J1 pin 8) connects the transformer to the phone jack and illuminates the LED. 1.6.1.5 Operating Voltage The selection of operating voltage (VDD = 3.3V or 5.0V) by jumper JP3 affects the choice of component values around the evaluation device. The following jumpers should be used to select appropriate component values: JP1, JP4, JP5, JP6 and JP7. All jumpers must be set the same way: use position 1-2 for VDD = 3.3V and position 2-3 for VDD = 5.0V operation. 1.6.1.6 Clock/Oscillator The evaluation device may use either an external clock or its own xtal oscillator. A 3.58MHz xtal is provided on-board for the latter method. Two jumpers JP8, which are normally fitted, select the xtal oscillator. An external clock may be supplied to JP8_1 (2) once the jumpers have been removed. The DTMF generator uses its own 3.58MHz xtal because the xtal oscillator is only operational when the generator is active and the evaluation device has a 'zero-power' mode (in which its xtal oscillator is disabled) preventing it from supplying a clock to the DTMF generator. 1.6.1.7 Ring/Line Reversal Detection Ring/line reversal detection is provided by components C3, C4, R1-R4 and D1-D4. The response time constant is set by components R5 and C5. The evaluation board has been fitted with suitable components for UK applications. See FX602 data sheet for further details. 1.6.1.8 Parallel Phone Detection Parallel phone detection is provided by components C17, C19-C23, R25, R29, R34, R35, R50, D20, D21 and TR4-TR7. It only communicates with a µC control board if jumper JP10 is fitted. A >2ms negative-going pulse on 602-LVCP signifies a phone line voltage drop of ≈ 4.5V; a 1ms negative-going pulse signifies a phone line voltage rise of ≈ 4.5V. 1.6.1.9 IDD Measurement The evaluation device IDD may be measured by removing jumper JP2 and replacing it with a multimeter. 1996 Consumer Microcircuits Limited 10 UM6020/4 Evaluation Kit User Manual for FX602 EV6020 1.6.1.10 DTMF Answerback Code The DTMF answerback code may be selected by an appropriate choice of the four jumpers JP9. Fitting a jumper sets that input to logic '0'. If not fitted, the input is pulled-up on-chip to logic '1'. Alternatively, all of the JP9 jumpers may be omitted and the DTMF generator may be driven from a µ C. A logic '1' on TX-DTMF (J1 pin 5) enables the generator and illuminates the LED.

A resistor (value ≈ 600Ω) is required for the evaluation board to operate correctly. 1.6.1.12 Voice Mute A mutable local voice input is provided on test point TP18. A logic '1' on /MUTE (J1 pin 20) unmutes the voice input and illuminates the LED. Access to voice signals is provided as follows: The hybrid receive output (Rx = remote voice) is located on test point TP16. The hybrid transmit output (Tx = local voice) is located on test point TP15. 1.6.1.13 Evaluation Device FX602/FX604/FX614 If the evaluation device is an FX602 it should be fitted in socket U2 position 1 and jumper JP10 should be fitted. If the evaluation device is an FX604 or FX614 it should be fitted in socket U2 position 2 and jumper JP10 should be removed, thus disabling the parallel phone detector output. This output is still available on test point TP17.
