EV9720 CML Microcircuits Evaluation Kit User Manual COMMUNICATION SEMICONDUCTORS UM9720/1 March 2013 Provisional Issue Features CMX972 Quadrature 20-300MHz C-BUS Interface to Host C Demodulator Options for on-chip PLL or External LO Easy Interfacing to PE0601-xxx Sources 1 Brief Description The EV9720 is an Evaluation Kit designed for evaluating and demonstrating the capabilities of the CMX972 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 EV9720 board. Note that as the EV9720 shares a common pcb with the EV9730, the pcb will not be fully populated. A C-BUS interface connector is provided for control of the EV9720 by a host microcontroller or CML PE0002 interface card. 2013 CML Microsystems Plc Evaluation Kit for CMX972 EV9720 CONTENTS Section Page 1 Brief Description .................................................................................................. 1 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 .................................................................................................. 5 4 Quick Start ............................................................................................................ 6 4.1 Hardware/Software Installation (for PE0002) ............................................ 6 4.2 First Initial Setup - EV9720 Quadrature IF Demodulator ....................... 6 4.2.1 Make External Connections and Apply Power ............................. 6 4.3 Second Configure - EV9720 Quadrature IF Demodulator ..................... 7 4.3.1 EV9720 Configuration .................................................................. 7 4.4 Third Operate - EV9720 Quadrature IF Demodulator ............................ 8 5 Signal Lists ........................................................................................................... 9 6 Circuit Schematics and Board Details ............................................................. 13 7 Detailed Description .......................................................................................... 15 7.1 Hardware Description .............................................................................. 15 7.1.1 Quadrature IF Demodulator ....................................................... 15 7.1.2 Oscillator .................................................................................... 15 7.1.3 Reference Oscillator................................................................... 15 7.1.4 Power Supply ............................................................................. 15 7.2 PC Control Software Description ............................................................ 16 7.2.1 The C-BUS Control Tab ............................................................. 17 7.2.2 The Registers Tab ..................................................................... 18 7.2.3 The Registers 2 Tab .................................................................. 18 7.2.4 The Script Handler Tab .............................................................. 19 7.3 Evaluation Tests ...................................................................................... 21 7.3.1 Quadrature IF Demodulator ....................................................... 21 7.4 Troubleshooting ...................................................................................... 23 7.4.1 General ...................................................................................... 23 7.4.2 Quadrature IF Demodulator Operation ...................................... 23 7.4.3 PLL/VCO Operation ................................................................... 24 8 Performance Specification ................................................................................ 25 8.1 Electrical Performance ............................................................................ 25 8.1.1 Absolute Maximum Ratings ....................................................... 25 8.1.2 Operating Limits ......................................................................... 25 8.1.3 Operating Characteristics........................................................... 26 Table Page 2013 CML Microsystems Plc 2 UM9720/1
