77 / 116 page Rev. 1.10 76 �e���a�� 1�� �01� Rev. 1.10 77 �e���a�� 1�� �01� HT98R068-1 Two Way Radio 8-Bit MCU HT98R068-1 Two Way Radio 8-Bit MCU Transmitter Compressor The device incorporates an optional syllabic compandor for both the transmit and receive mode. This compresses the audio band signals before transmission to enhance the overall dynamic range. The relationship between the input and output voltage of the compandor is shown in the following figure. Compander voltage-voltage response Transmitter Sub-audio Encoders Sub-audio signaling is available in the audio band below 260Hz. When sub-audio signaling is enabled, the 300Hz HPF in the audio section should also be enabled to remove the sub-audio signaling from the actual audio signals (for both Tx and Rx). Both CTCSS tones and DCS codes are supported. Except for the 51 defined CTCSS tones, users can define their specified tones using registers. The DCS coder/decoder includes a 23-bit mode with both normal and inverse modulation formats and a 134Hz end of transmission burst. Transmitter In-Band Signaling The device includes a programmable in-band tone set or an arbitrary single user-tone between 300Hz and 3000Hz. By default, the device will use an EEA selective call defined tone set; however this may be changed to any valid tone within its operational range using registers. As well as the selective call defined tone sets, standard dual tone multiple frequency, DTMF, is also supported in the in-band signaling mode. Supported Different Combination Functions For optimal power consumption, the audio processor can be set to operate with different operation frequencies for different functional requirements. The accompanying table provides a reference for the required audio processor system clock for different applications. |
