... Unlike the MLS ChipCorder series, this device provides higher sampling frequency and a signal path with SNR equivalent to 12-bit resolution. The ISD2100 can take digital audio data via SPI interface. When SPI interface is chosen, the sample rate of the audio data sent must be one of the ISD2100 supported sample rates. ...

... MOSI), and a data output (Master In Slave Out - MISO). In addition, for some transactions requiring data flow control, a RDY/BSYB signal (pin) is available. The ISD2100 supports SPI mode 3: (1) SCLK must be high when SPI bus is inactive, and (2) data is sampled at SCLK rising edge. A SPI transaction begins on the falling edge of SSB and its waveform is ...
