PCM1808 Master Mode Question

Other Parts Discussed in Thread: PCM1808

Hi Expert,

Why PCM1808 D/S page14 shows the master mode will divide down the SCLK to generate frequencies of 128fs and 64fs?

Does it mean the master mode only support 128fs and 64fs? Thanks!

    Hi Jerry,

    128Fs and 64Fs are generated internally by the device to drive the digital filter and delta-sigma modulator. These clocks are generated from the system clock, which supported frequencies are 256Fs, 384Fs and 512Fs.

    Best Regards,
