Manufacturer:TI Description:(2) Master Clock (MCK) Input 1-bit audio signals such as PWM or PDM to the DIN1 and DIN2 pins. By setting the SEL pin to H, master clock (MCK) synchronizes the audio signal inputs (DIN1 and DIN2). In case of SEL = L, input signals go into the amplifier circuits by own timing. Therefore, it requires careful design of PCB patterns from DSP to NJU8714. The setup time and the hold time should be kept in the AC characteristics because DIN1 and DIN2 are fetched with the rising edge of MCK. MCK requires jitter-free or jitter as small as possible because the jitter downs S/N ratio. |
