Evaluation Kit for CMX990
EV9900
Maximum Usable Sensitivity
Typically –117dBm for 1% BER
Error rate at High Input Levels
See section 6.5.
Co-channel Rejection
With an interferer on the same frequency this is typically 8-10dB for 12.5kHz channel spacing
operation (8kbit/s). See also section 6.7.1.
Adjacent Channel Rejection (ACR)
ACR performance is limited by local oscillator phase-noise. The performance of the EV9900
meets Mobitex MIS requirements but does not meet EN 300 113.
Spurious Response Rejection
A front-end SAW filtering is not provided on the EV9900 so spurious response rejection is not
guaranteed.
Blocking or Desensitisation
Blocking performance is about 80dB. This will be improved in later silicon.
