    Additional units can be added into a design to cater for applications that require more channels. The FMC88108-6 is a compact unit requiring only 1RU rack space. The unit can be configured to customer requirements and is primarily used for on-frequency (non-translating) operation, but can also be used in a frequency shifted (translating) mode of operation if desired.

    When operated from an AC power source this unit complies with the Australian AS/NZS 60950 equipment safety standard. There is no surge protection built into the PSU of the FMC88108-6, so additional site specific lighting protection, voltage surge protection and earth bonding is recommended to reduce the risk of damage.

The BIF audio feed can be activated by grounding pin 1 (100mA sink) on the telemetry D9 connector. (Ground is available on pins 2 and 3) The BIF deviation levels for all carriers can be adjusted via a single potentiometer R13 on the display/distribution module.

    User’s Manual INS-42037-1: FMC88108-6 Synthesizer and Loop Filter (87.5MHz – 108MHz). The synthesizer consists of a single loop with a divide by 64 pre-scaler IC14. Direct carrier modulation is used in this application. The 6.4MHz crystal circuit provides the reference for the synthesizer IC10. The reference is then divided by 8192 by IC10 to 781.25Hz.
