+ | ADCaudio01B is an innovated version of an older module, with an already integrated crystal oscillator that eliminates the need for a further module that served as an external generator of a sampling clock. It uses ADC [[https:// | ||
+ | |||
+ | The main parameters are as follows: | ||
+ | * Sampling frequency 8 - 192 kHz | ||
+ | * Distortion - 102 dB | ||
+ | * I²S interface | ||
+ | * 24 bit resolution | ||
+ | * SNR 111 dB | ||
+ | |||
+ | ===== ADCaudio01A ===== | ||
+ | |||
+ | For testing purposes we used module [en: | ||
+ | |||
+ | For CP2114, a configuration 0 works without a further setting up - so in case of CS42L55 | ||
+ | |||
+ | * DACSEL0 az DACSEL3 = L | ||
+ | |||
+ | For WM8786 a following configuration is functional: | ||
+ | * MS0 = L | ||
+ | * AUDIOF0 = L | ||
+ | * AUDIOF1 = H | ||
+ | * OSR0 = 0 | ||
+ | * OSR1 = 0 | ||

+ | | MCLK | <= | MCLK | | ||
+ | | BCLK | <= | SCK | | ||
+ | | LRCLK |<= | LRCK | | ||
+ | | DOUT | => | SDIN | | ||

+ | **// There seems to be a crosstalk between L and R channel.// | ||
