Clock and Reset Timing
To reset the AMBE-2000 chip, the reset signal must be held low for a minimum of 50 µs. The recovery time from reset is
approximately 95 ms. In other words, 95 ms after the rising edge of the reset signal the AMBE-2000™ starts processing PCM
samples. The first packet will be ready after 252 PCM samples are read.
