Baseband processor for marine automatic identification
15 June 2005
DSP, Micros & Memory
The CMX910 is a highly integrated baseband signalling processor IC from CML, for class A and class B marine automatic identification system (AIS) applications.
Half duplex in operation, it comprises two parallel I and Q Rx paths, and one Tx path, all configurable for AIS or FSK (DSC) operation. The device performs channel filtering and signal modulation/demodulation, along with associated AIS functions such as training sequence detection, NRZI conversion and HDLC processing (flags, bit stuffing/de-stuffing, CRC generation/checking and slot-timing).
The 1200 bps FSK demodulator interface provides the third parallel decode path, using an external FSK modem, required by the AIS class A market. Integrated Rx/Tx data buffers and a slot/sample timer are also provided - reducing the processing requirements of the host microcontroller. The thoughtful provision of a C-BUS controlled interface expansion port, device enabled ports and versatile auxiliary ADCs and DACs, further simplify system hardware design, reducing the overall end-equipment cost and size.
The CMX910 is also capable of transmitting on either AIS channel (GMSK-9600 bps) or FSK (1200 bps) on the DSC channel, as required. As an ultra-low-power IC, many of the CMX910s on-chip functions can be powersaved when not actively required.
