The dip switch supports 16 frequency points (16 Channels), which are categorized into Band A and Band B, with corresponding parameter settings for each channel as follows:
- For Band A:
CH1 corresponds to a frequency of 6150 MHz; paired with the settings: L/CH1 = 0, C/CH2 = 0, D/CH3 = 0, BAND = 1, SPI/EN = 0
CH2 corresponds to a frequency of 6250 MHz; paired with the settings: L/CH1 = 1, C/CH2 = 0, D/CH3 = 0, BAND = 1, SPI/EN = 0
CH3 corresponds to a frequency of 6350 MHz; paired with the settings: L/CH1 = 0, C/CH2 = 1, D/CH3 = 0, BAND = 1, SPI/EN = 0
CH4 corresponds to a frequency of 6450 MHz; paired with the settings: L/CH1 = 1, C/CH2 = 1, D/CH3 = 0, BAND = 1, SPI/EN = 0
CH5 corresponds to a frequency of 6550 MHz; paired with the settings: L/CH1 = 0, C/CH2 = 0, D/CH3 = 1, BAND = 1, SPI/EN = 0
CH6 corresponds to a frequency of 6650 MHz; paired with the settings: L/CH1 = 1, C/CH2 = 0, D/CH3 = 1, BAND = 1, SPI/EN = 0
CH7 corresponds to a frequency of 6750 MHz; paired with the settings: L/CH1 = 0, C/CH2 = 1, D/CH3 = 1, BAND = 1, SPI/EN = 0
CH8 corresponds to a frequency of 6850 MHz; paired with the settings: L/CH1 = 1, C/CH2 = 1, D/CH3 = 1, BAND = 1, SPI/EN = 0
- For Band B:
CH1 corresponds to a frequency of 6950 MHz; paired with the settings: L/CH1 = 0, C/CH2 = 0, D/CH3 = 0, BAND = 0, SPI/EN = 0
CH2 corresponds to a frequency of 7010 MHz; paired with the settings: L/CH1 = 1, C/CH2 = 0, D/CH3 = 0, BAND = 0, SPI/EN = 0
CH3 corresponds to a frequency of 7050 MHz; paired with the settings: L/CH1 = 0, C/CH2 = 1, D/CH3 = 0, BAND = 0, SPI/EN = 0
CH4 corresponds to a frequency of 7070 MHz; paired with the settings: L/CH1 = 1, C/CH2 = 1, D/CH3 = 0, BAND = 0, SPI/EN = 0
CH5 corresponds to a frequency of 7100 MHz; paired with the settings: L/CH1 = 0, C/CH2 = 0, D/CH3 = 1, BAND = 0, SPI/EN = 0
CH6 corresponds to a frequency of 7130 MHz; paired with the settings: L/CH1 = 1, C/CH2 = 0, D/CH3 = 1, BAND = 0, SPI/EN = 0
CH7 corresponds to a frequency of 7150 MHz; paired with the settings: L/CH1 = 0, C/CH2 = 1, D/CH3 = 1, BAND = 0, SPI/EN = 0
CH8 corresponds to a frequency of 7210 MHz; paired with the settings: L/CH1 = 1, C/CH2 = 1, D/CH3 = 1, BAND = 0, SPI/EN = 0
Test Condition:
- Ambient temperature: 25℃
- Video input voltage: 1.0Vp-p,150 (IRE)
Attention:
- When the SPI/M is at a high level, the module receives the SPI signal to control the frequency, if no frequency setting or invalid setting is received, it will work at 6150MHz by default, and the frequency range can be set to 6G~7.5G, 1MHz steps.
- SPI signal level 3.3V, up to 100K rate.
