1.1 Brief Description
The EV1050 Evaluation Kit comprises a single board containing an FX105A. Switches select variable resistors for adjusting the detect frequency, bandwidth and response time. Many of the fixed components are socketed so that they can be changed by the user. The EV1050 board is powered from a single 8 - 35V external dc power supply; an on-board regulator sets 3.0V or 5.0V operation. An LED indicates the status of the detect output. The supply cu rrent of the FX105A may be measured by removing the appropriate jumper. Test points are provided for the signal input, the VCO output and the detect output. A user prototyping area is provided.

1.2 Preliminary Information
1.2.1 Laboratory Equipment
The following laboratory equipment is needed to use this evaluation kit: 1.2.1.1 8 - 35V dc power supply. 1.2.1.2 An input signal source.
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. Partially damaged circuits may function erroneously, leading to misleading results. Observe ESD precautions at all times when handling this product.
1.2.2.2 Conten ts - Unpacking
Please ensure that you have received all of the items listed on the separate information sheet (EK1050) and notify CML within 7 working days if the delivery is incomplete.

1.3 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 EV1050 COMES PRE-CONFIGURED FOR OPERATION AT 5.0V. To select 3.0V operation, short circuit JP1 with an insulated jumper socket. WHEN THE SWITCHES (SW1 TO SW4) ARE SET TO USE THE FIXED VALUE RESISTORS, THE EV1050 DETECTS A 440 Hz SIGNAL WITH A 6% (APPROX.) BANDWIDTH. The default settings in the spreadsheet reflect the fixed component values used in the EV1050.
1.3.2 Operation
Apply an input signal between testpoint TP9 and V SS . The detect output can be monitored at testpoints TP1 or TP2 and is indicated by LED D2. Select R1V with switch SW1 to adjust f o . Select R2V with switch SW2 and RVV with switch SW4 to adjust the bandwidth. Select RWV with switch SW3 to adjust the response and de-response times. For all switches, setting the paddle away from the prototype area selects variable resistors and setting the paddle towards prototype area selects fixed resistors. Please refer to the FX105A data sheet for further information on the operation of this integrated circuit and for details of the circuit design equations which govern the choice of component values.
1.3.3 Spreadsheet
An Excel spreadsheet has been included with this kit to simplify the selection of component values. The design requirements should be entered into column "B" in the area shaded green on the spreadsheet. The calculations will be automatically updated and intermediate results are shown in the non-shaded area of column "B". A convenient value for C1A and C1B is chosen (these values should be identical) and the corresponding value of R1 is read from column "F" in the same row. Column "G" indicates whether this choice of values is "OK" or "out of range". In the latter case, the FX105A will probably still operate, but the actual component values may require adjustment from the calculated spreadsheet values. The choice of component values for (C2A, C2B, RV) and (C3A, C3B, RW) is made in the same way. Note that it is not necessary to use the same row for (C2A, C2B, RV) and (C3A, C3B, RW) as was used for (C1A, C1B, R1). The value of R2 is shown in column "B". The choice of C4 is made by reading the value in column "K" on the same row as was used for choosing the (C2A, C2B, RV) values. This spreadsheet can only approximate to the actual component values required. Please note that some device parameters (particularly V TH ) can vary from one silicon batch to another, and in turn will cause a variation in detector performance. Component values should be carefully chosen to optimise this performance spread.

1.6 Detailed Description
1.6.1 Hardware Description
JP1 is used to select the operating voltage. Open circuit selects 5.0V operation (default ) and short circuit selects 3.0V operation. 1.6.1.1 Discrete components around the FX105A which the user may wish to alter are socketed. Required values for a particular application can be calculated from the formulae given in the FX105A datasheet. Alternatively, a sp readsheet is provided in this kit to aid the user in selecting component values. The required circuit parameters are entered in the green area and suggested component values are shown to the right of the spreadsheet.
1.6.1.2 IDD Measurement
The current consumption of the FX105A may be measured by removing the jumper on JP2 and replacing it with a multimeter.

In the process of creating a more global image, the three standard product semiconductor companies of CML Microsystems Plc (Consumer Microcircuits Limited (UK), MX-COM, Inc (USA) and CML Microcircuits (Singapore) Pte Ltd) have undergone name changes and, whilst maintaining their separate new names (CML Microcircuits (UK) Ltd, CML Microcircuits (USA) Inc and CML Microcircuits (Singapore) Pte Ltd), now operate under the single title CML Micro- circuits. These companies are all 100% owned operating companies of the CML Microsystems Plc Group and these changes are purely changes of name and do not change any underlying legal entities and hence will have no effect on any agreements or contacts currently in force. CML Microcircuits Product Prefix Codes Until the latter part of 1996, the differentiator between products manufactured and sold from MXCOM, Inc. and Consumer Microcircuits Limited were denoted by the prefixes MX and FX respectively. These products use the same silicon etc. and today still carry the same prefixes. In the latter part of 1996, both companies adopted the common prefix: CMX.
