Hello Team,
I got some question from customer. Can you please confirm them?
Q1. Datasheet says
THD+N=-93dB at the condition of VIN=-0.5dB, fs=48kHz, Ta=-40C~125C
How much is the THD+N for below condition?
THD+N= ?? dB at the condition of VIN=-1.0dB, fs=48kHz, Ta=-40C~125C
Q2. Please tell me the behavior of internal reset when VDD = less than 2.2V.
* I would like to confirm if there are any concerns when the power up timing between PCM1808-Q1 and the other devices shift
Q3. For Pin.13 and 14, The datasheet says there generally used antialiasing low pass filter (100 Ω and 0.01 μF to 1 kΩ and 1000 pF) for the pins. Can you let me know the input condition?
If the filter is 100Ω, 0.01uF, the fc will be 159kHz.
For example, if fs = 48kHz, we should cuts 24kHz or more.
It seems that there is no effect at fc = 159kHz.
Should the filter value be selected according to the input conditions?
thanks,
Yuta Kurimoto
