Si47xx-EVB There are 16 different group types in the RDS/RBDS standard, and for every group the following information is always transmitted: 1. Program Identification (PI) 2. Program Type (PTY) The GUI makes it easy to send data in three of the following group types: 1. Group Type 0: Program Service (PS) 2. Group Type 2: Radio Text (RT) 3. Group Type 4: Clock Time (CT) It is possible to send data in the other group types, but the user has to manually enter the data in hexadecimal code.
PAGE 56
Si47xx-EVB 5.10.1. Basic The RDS Transmit Window is divided into three categories: 1. General 2. Program Service 3. Buffers In the basic section, we will cover two out of the three categories: the General and Program Service. In the General category, the user can set the PI and PTY data. In the Program Service, the user can set the PS data (Group Type 0). The following diagram shows a step-by-step explanation: 1 2 3 4 5 Figure 46. Basic RDS Message Illustration 1.
PAGE 57
Si47xx-EVB 5.10.2. Intermediate In the intermediate section, we will cover the buffers category of sending the RDS data with the device, in particular we will send Group Type 2 (Radio Text) and Group Type 4 (Clock Time). The following diagram shows a step-by-step procedure to send the buffers data in addition to the General and Program Service data covered in the basic section. 1 2 3a 3 5 6 4 Figure 47. Intermediate RDS Message Illustration 1.
PAGE 58
Si47xx-EVB value is set to anything other than 100%. 5. Clicking the "Add Time" button here will add the current time as a RDS Group Type 4 message to the GUI FIFO Buffer queue. 6. Clicking the "Clear Buff & Send" button will upload the message from the FIFO Buffer Indicator Window into the FIFO Buffer inside the device. The FIFO Buffer on the part will only send the messages contained in the buffer once. A good example of using FIFO buffer is when you want to send the time data.
PAGE 59
Si47xx-EVB uploaded means that the RT is uploaded with the flag set. Un-checking this box when an RT is uploaded means that the flag is not set. This flag tells the receiver that when the flag toggles from set to reset or vice versa, the receiver will clear the display before showing the next RT. 5.

PAGE 85
Si47xx-EVB Figure 66. FM Configuration Helper Window (SNR Based Hi-cut) In the example shown in Figure 66, the current level marker shows that hi-cut filter is set at 6 kHz. This is determined by both SNR and multipath conditions. Current SNR is 5 dB. Hi-cut SNR Low Threshold is set at 15 dB and hi-cut minimum frequency is set at 6 kHz. SNR is the determining factor in this case as it is already lower than the low threshold.
PAGE 86
Si47xx-EVB Figure 67. FM Configuration Helper Window (Softmute) In the example shown in Figure 67, the current level marker shows that Soft Mute level is 0 dB. SNR threshold is programmed as 4 dB and max attenuation is 16 dB. Since the SNR reported by the part is 5 dB, which is above the threshold, the softmute level is 0 dB. The graph shows the current state of SNR (green diamond) and plot shows the softmute profile based on max attenuation, threshold and slope settings.
PAGE 87
Si47xx-EVB Figure 68. FM Configuration Helper Window (SNR Based Blend) In the example shown in Figure 68, the Current Level marker shows that Stereo % is 56%. SNR threshold is programmed as 14 dB (and below) for full mono and 30 dB (and above) for full stereo. Since the SNR reported by the part is in between the thresholds, the stereo level is 56%. RSSI and Multipath do not factor in here as they are both at levels that would set the part in full stereo.
PAGE 88
Si47xx-EVB Figure 69. FM Configuration Helper Window (RSSI Based Blend) In the example shown in Figure 69, the Current Level marker shows that Stereo % is 56%. RSSI threshold is programmed as 30 dBµV (and below) for full mono and 49 dBµV (and above) for full stereo. RSSI reported by the part is in between the thresholds however the final blend percentage is determined by SNR and the stereo level is 56%. Multipath does not factor in here as it is at a level that would set the part in full stereo.
PAGE 89
Si47xx-EVB In the example shown in Figure 70, the Current Level marker shows that Stereo % is 50%. Multipath threshold is programmed as: 60% (and above) for full mono and 20% (and below) for full stereo. Multipath reported by the part is 11% which would put the part in full stereo. However the final blend percentage is determined by SNR and the stereo level is 56%.
