FX919A : The FX919A is a CMOS integrated circuit that contains all of the baseband signal processing and Medium Access Control (MAC) protocol functions required for a high performance 4-level FSK Wireless Packet Data Modem. It interfaces with the modem host processor and the radio modulation/demodulation circuits to deliver reliable two-way transfer of the application data over the wireless link. The FX919A assembles application data received from the processor, adds forward error correction (FEC) and error detection (CRC) information and interleaves the result for burst-error protection. After adding symbol and frame sync codewords, it converts the packet into filtered 4-level analogue signals for .

FX949 : The FX949 is a low power CMOS integrated circuit which performs all of the real-time signal and data format-management functions required for full-duplex operation of a CDPD Mobile End Station. The FX949 interfaces directly with the analogue modulation and demodulation circuits of the radio and the host radio/application processor bus. It accepts application data from the processor, constructs a correct Reverse Channel packet containing this data and converts the packet to GMSK analogue signals for transmission. In receive, Forward Channel GMSK signals from the discriminator are demodulated, the packet disassembled, error checked, and the recovered application data passed to the processor. T.

FX980 : This device is intended to act as an interface between the analogue and digital sections of a Digital Radio System, and performs many critical and DSP-intensive functions. The chip is designed with the necessary capability to meet the requirements for use in both mobile and base station applications in Terrestrial Trunked Radio (TETRA) systems. The transmit path comprises all the circuitry required to convert digital data into suitably filtered analogue I and Q signals for subsequent up-conversion and transmission. This includes digital control of the output amplitudes, digital control of the output offsets and fully programmable digital filters: default coefficients provide the RRC respons.
