Over-air commands enable a Tx host to select optimum modulation type and coding per burst to suit application message size and link channel quality. They can also relax required Rx host parsing speed. SPI Thru-Port macros speed serial slave control for shorter Tx/Rx mode transitions.
The CMX7164 covers both constant envelope and linear modulation schemes including: GMSK/GFSK, 2/4/8/16-level FSK, 4/16/32/64-QAM and V.23 to provide a suitable platform for customer-specific modulation schemes. Together these features make the CMX7164 a truly universal wireless data modem solution.
Combining the CMX7164 with CML’s RF building blocks enables the highest integration and performance radio data modem application to be developed.
The DE9941 demonstrator/evaluation board is available and enables the CMX7164, CMX994E direct conversion receiver and CMX998 Cartesian feedback loop transmitter to be demonstrated/evaluated.
The CMX7164 is available now, offering low power 3.3V operation in small VQFN/LQFP packaging.
