Pdm clock

SpletPulse-width modulation(PWM) is a special case of PDM where the switching frequency is fixed and all the pulses corresponding to one sample are contiguous in the digital signal. For a 50% voltage with a resolution of 8-bits, a PWM waveform will turn on for 128 clock cycles and then off for the remaining 128 cycles. Splet26. feb. 2024 · The PDM clock is determined by dividing a high frequency clock (16307.692kHz) by 8 = 2038.46kHz, which is further divided by 64 to determine the PCM sampling rate = 31.85kHz. This PCM data is then downsampled by a factor of 4, and written to the I2S TX_FIFO where 16 bit words are output at a frame rate of 7.963kHz.

Splet13. mar. 2024 · You'll usually see PDM defined as a function which converts an analog sample (or discretized analog sample), once per clock cycle, to a digital signal (high or low). That is useful for signal analysis and mathematical treatment, but it isn't useful for hobbyists like myself that would just like to see what such signals look like. SpletCLOCKING The ADAU7002 requires a BCLK rate that is a minimum of 64× the LRCLK sample rate.
