Product description

The CMX7241/CMX7341 provides a common platform that can deliver marine radio solutions based on a configurable baseband processor with direct connection to an I/Q based RF receiver. The chip-set comprising CMX7341 Marine Common Platform Processor + CMX994A Direct Conversion Receiver (DCRx) enables a high integration and cost-effective radio solutions to be realised.

The CMX7241 and CMX7341 provide the same system functionality and can accept the same FI but are targeted at different system implementations:

  • CMX7241 has analogue inputs suitable for traditional limiter/discriminator designs.
  • CMX7341 has a differential I/Q Rx interface for optimum performance and direct connection to CML’s CMX994A/E Direct Conversion Receiver ( DCRx) ICs
