Digital attenuator
different ways. The relationship with the command’s output is shown below.
Digital de-emphasis filter
The digital attenuation command is enabled when D7 = “L”. The attenuation data can be set in 128
01 (HEX) to 7E (HEX): The attenuation value is obtained with the following equation.
Example: In case of attenuator = 7 A
The Digital De-emphasis setting mode is enabled when D7 = “H”.
Controlled with µ EMP and µ BS signal.
ATT = 20 ℓog (input data/127) dB
ATT = 20 ℓog (122/127) dB = − 0.349dB
