Evaluation Kit for the CMX983


Product Data
EV9830 User Manual (rev3)


  • External VCO connection option to both fractional-N synthesisers
  • 900MHz and 2.1GHz VCOs fitted
  • Access to RF, control and baseband signals via connectors and test points
  • On-board supply regulators operate from a dual +/6V supply
  • Command and control by PC via the PE0003 Interface Card or user’s microcontroller development application or emulator
  • 19.2MHz oscillator or external clock input to CMX983
  • Differential to single-ended instrumentation interfaces
  • On-board access to all CMX983 signals, commands and data

The EV9830 Evaluation Kit allows evaluation of the CMX983 Baseband Interface for Digital Radio.

For evaluation of the Fractional-N synthesisers, a 900MHz VCO is fitted with connections to synthesiser 1 and a 2.1GHz VCO is fitted with connections to synthesiser 2. Test pads are also provided for connection to an external VCO.

An instrumentation interface with single-ended signal connections to differential baseband I/Q connections on the CMX983 is provided to allow easy connection of proprietary test equipment.

The board also incorporates all of the necessary power supply regulation facilities for operation from a dual +/6Vsupply.

The board is fitted with a C-BUS connector allowing the EV9830 to be operated by connection to either of the two C-BUS ports on a CML PE0003 interface card used with the associated PC GUI software. A separate ‘host’ header is provided with both C-BUS and fast serial port connections.

EV9830 FAQ

Q. The EV9830 works intermittently with a PE0003 kit. Is there a problem?

A. The EV9830 and PE0003 has a hardware reset that should be toggled by the host. This pin is not accessible to the PE0003 so we recommend that C11 is replaced to extend the time that the hardware reset is held low during power up. Guidance for the location and replacement of C11 is given in the latest EV9830 User Manual. This replacement is only required on early EV9830 kits.
