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.

Parallel interface description

Serial interface consists of 9 signals: A0-A7 (tuning frequency code) and STB (strobe).

Tuning frequencycode

Tuning frequency code is calculated by X₁₀ conversion into binary code. X₁₀ is calculated by the formula:

f₀ — tuning frequency; f_l — low frequency of the band; f_h — high frequency of the band.
