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 current 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.

1.2.1.1 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 Contents - 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.

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 VSS. The detect output can be monitored at
testpoints TP1 or TP2 and is indicated by LED D2.
Select R1V with switch SW1 to adjust fo.
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 VTH) 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.

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 spreadsheet 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.

CML Product Data
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 Microcircuits.
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.
