<\/p>\n
I explained that the LRCLK that came out earlier is a signal that distinguishes between L and R. In the I2S format regulations, the signal level is specified as L channel for 0V (low) and R channel for high.<\/p>\n
Let’s take a look at the LRCLK waveform that actually corresponds to the sample rate.<\/p>\n

LRCLK 44.1KHz CD Playback<\/p>\n
image051<\/p>\n
LRCLK 96KHz LPCM 96 kHz playback<\/p>\n
image053<\/p>\n
LRCLK 192 KHz LPCM 192 KHz playback<\/p>\n
image055<\/p>\n
LRCLK 384 kHz LPCM 384kHz playback<\/p>\n
Therefore, the sample rate matches LRCLK. COMBO384 supports LPCM maximum sample rate up to 384KHz.<\/p>\n
7. BCLK<\/p>\n
It is sometimes referred to simply as CLK, commonly referred to as a bit clock, and is the reference clock for reading 32 bits. So 32 times the sample rate and 64 times the LR channel frequency combined.<\/p>\n
It will be the second frequency in the frequency calculation above. In the case of 44.1 KHz, it will be 2.8224 MHz.<\/p>\n
Let’s take a look at the actual BCLK.<\/p>\n

BCLK 2.8224MHz CD 44.1 kHz<\/p>\n
image037<\/p>\n
BCLK 6.144MHz LPCM 96 kHz<\/p>\n
image039<\/p>\n
BCLK 12.288MHz LPCM 192 KHz<\/p>\n
image041<\/p>\n
BCLK 24.5760MHz LPCM 384kHz<\/p>\n
This BCLK is also issued during DSD.<\/p>\n
image045<\/p>\n
DSD64 2.8224 MHz<\/p>\n
image043
\nDSD128 5.6448 MHz<\/p>\n
image047<\/p>\n
DSD256 11.2896 MHz<\/p>\n
It is often mentioned that it supports 11.2MHz in the introduction of DSD, but to be exact, it is this frequency.<\/p>\n
The waveform is not square because the oscilloscope has a low frequency bandwidth. It is actually a square wave.<\/p>\n
How was it?<\/p>\n
Did you understand the frequencies used for the audio?<\/p>\n
I think you can see audio frequencies in various situations, but if you remember that this frequency meant something like this, I think you may feel more familiar with digital audio.<\/p>\n
In Marz, this DSD256 (11.2896MHz above) LPCM is 384KHz sells an amplifier equipped with a COMBO384 corresponding to.<\/p>\n
Since it supports high sample rates, it can play high-resolution music.<\/p>\n
