Serial interface description
Serial interface consists of 3 signals: CLK (clock), DI (data input), STB (strobe). Data input is 11 bits code. First 8 bits determine the tuning frequency and the last 3 bits determine the frequency band.
Frequencybandcode
Frequency band | D9 | D10 | D11 |
1,5–4 MHz | 1 | 0 | 0 |
4–10 MHz | 0 | 1 | 0 |
10–30 MHz | 0 | 0 | 1 |
Tuning frequencycode
Tuning frequency code is calculated by X10 conversion into binary code. X10 is calculated by the formula:
f0 — tuning frequency; fl — low frequency of the band;fh — high frequency of the band.
Example
If you wish to tune to 8.02 MHz, the tune word is:
