CML CMX7364
The CMX7364 Multi Mode Modem is a half-duplex device currently supporting 4-Level FSK modes in 12.5 or 25kHz channel spacings under host control. Its Function Image™ (FI) is loaded to initialise the device and determine modulation types. The CMX7364 loaded with 7364FI-8.x supports 4-FSK modulation, root raised cosine filtered with =0.2 with sinc filtering (optional).| Part No. | CMX7364 |
