CML Microcircuits has released new function images the CMX7131 and CMX7141 digital PMR processors.
CML Microcircuits has added dPMR (Digital Private Mobile Radio) modes 1, 2 and 3 and ARIB STD-T102 to the CMX7131 and CMX7141. The devices are now market-leading digital PMR processors supporting 6 systems and growing; dPMR TS 102 490, DCR ARIB-T98, NXDN, Analogue PMR and now dPMR TS 102 658 and ARIB STD-T102.
The dPMR Mode 1, 2 and 3 Function Image implements a half-duplex 4FSK modem and a large proportion of the dPMR Air Interface, Data Link and Call Control layers. In conjunction with a suitable host and a limiter/discriminator-based RF transceiver, a compact, low-cost, low-power digital PMR radio conforming to ETSI’s dPMR standard TS 102 658 can now be realised.
The 7131/7141FI-2.x Function Image implements a half-duplex 4FSK modem and a large proportion of the DCR Air Interface, Data Link and Call Control layers. In conjunction with a suitable host and a limiter/discriminator based RF transceiver, a compact, low cost, low power digital PMR radio conforming to ARIB’s T98 Digital Convenience Radio standard can be realised. Dual mode, analogue/digital PMR operation can also be achieved with the CMX7131/CMX7141.
