EV9700 CML Microcircuits Evaluation Kit User Manual COMMUNICATION SEMICONDUCTORS UM9700/4 August 2012 Provisional Issue Features CMX970 Quadrature IF Demodulator Frequency Range 20 300 MHz C-BUS Interface to Host Microcontroller Direct Control Mode (host-less operation) Easy Interfacing to PE0601-xxxx 1 Brief Description The EV9700 is an Evaluation Kit designed for evaluating and demonstrating the capabilities of the CMX970 integrated circuit. All the circuits necessary to demonstrate the facilities provided by the IC, such as matching circuits, power supply regulators, etc are provided on the EV9700 board. A C-BUS interface connector is provided for control of the EV9700 by a host microcontroller or CML PE0002 interface card. The CMX970 can also be used in a Direct Control mode, where a host or PE0002 is not required. 2012 CML Microsystems Plc Evaluation Kit for CMX970 EV9700 CONTENTS Section Page 1 Brief Description .................................................................................................. 1 1.1 History ....................................................................................................... 3 2 Block Diagram ...................................................................................................... 4 3 Preliminary Information ....................................................................................... 5 3.1 Laboratory Equipment ............................................................................... 5 3.1.1 Power Supply ............................................................................... 5 3.1.2 Control Interface ........................................................................... 5 3.2 Handling Precautions ................................................................................ 5 3.2.1 Static Protection ........................................................................... 5 3.2.2 Contents - Unpacking................................................................... 5 3.3 Approvals .................................................................................................. 6 4 Quick Start ............................................................................................................ 7 4.1 First Initial Setup..................................................................................... 7 4.1.1 Make External Connections and Apply Power ............................. 7 4.1.2 Hardware/Software Installation (for PE0002) ............................... 8 4.2 Second Configure .................................................................................. 8 4.2.1 EV9700 Configuration .................................................................. 8 4.3 Third Operate ......................................................................................... 9 5 Signal Lists ......................................................................................................... 10 6 Circuit Schematics and Board Details ............................................................. 13 7 Detailed Description .......................................................................................... 15 7.1 Hardware Description .............................................................................. 15 7.1.1 Power Supply ............................................................................. 15 7.1.2 CMX970 ..................................................................................... 15 7.1.3 CMX970 Direct Control Mode .................................................... 15 7.2 PC Control Software Description ............................................................ 16 7.2.1 The C-BUS Control Tab ............................................................. 18 7.2.2 The Registers Tab ..................................................................... 19 7.2.3 The Script Handler Tab .............................................................. 20 7.3 Evaluation Tests ...................................................................................... 21 7.3.1 I/Q Signals .................................................................................. 21 7.3.2 Noise figure ................................................................................ 22 7.4 Troubleshooting ...................................................................................... 23 7.4.1 General ...................................................................................... 23 7.4.2 Quadrature IF Demodulator Operation ...................................... 23 8 Performance Specification ................................................................................ 24 8.1 Electrical Performance ............................................................................ 24 8.1.1 Absolute Maximum Ratings ....................................................... 24 8.1.2 Operating Limits ......................................................................... 24 8.1.3 Operating Characteristics........................................................... 25 2012 CML Microsystems Plc 2 UM9700/4
