What is Mclk frequency?
MCLK is 256 x 48 kHz = 12.288 MHz.
What is I2S BCLK?
I2S is a protocol between two devices where one is the master and one is the slave . The protocol is made up of four signals shown in Table 1. MCLK Clock line, driven by external oscillator BCLK Bit clock. This is a fixed divide of the MCLK and is driven by the master.
Why is I2S used?
I2S (Inter-IC Sound), is an electrical serial bus interface standard used for connecting digital audio devices together. It is used to communicate PCM audio data between integrated circuits in an electronic device.
What is I2S mode?
The Integrated Inter-IC Sound Bus (I2S) is a serial bus interface standard used for connecting digital audio devices together. The specification is from Philips Semiconductor (I2S bus specification; February 1986, revised June 5, 1996). The I2S component operates in master mode only.
What is Mclk in BIOS?
The MCLK Spread Spectrum BIOS feature controls spread spectrum clocking of the memory bus. It usually offers three levels of modulation – 0.25%, 0.5% or 0.75%. They denote the amount of modulation around the memory bus frequency. However, system stability may be compromised if you are overclocking the memory bus.
What is system memory multiplier?
System Memory Multiplier: Left on Auto, your BIOS will determine the safest multiplier, or FSB:DRAM ratio, and resulting memory frequency for your RAM based on its pre-programmed SPD settings. If overclocking or tuning for additional performance, you can manually set the multiplier.
What is the difference between I2C and I2S?
In Summary, the I2C bus is used to connect the microcontroller and its peripheral devices while the I2S bus focuses on the audio data transmission between digital audio devices.
What is the difference between I2S and TDM?
An I2S data stream can carry one or two channels of data with a typical bit clock rate between 512 kHz, for an 8 kHz sampling rate, and 12.288 MHz, for a 192 kHz sampling rate. Time division multiplexed (TDM) formats are used when more than two channels of data are to be transferred on a single data line.
What is I2S vs I2C?
What should BCLK frequency be?
On our configuration, we achieved a stable BCLK Frequency of 148 MHz with no USB- or SATA-related issues. To prevent the reference clock frequency from rising too high, it is necessary to lower the CPU and memory multipliers….Modifying BCLK Frequency.
Boot | OS |

148 MHz | 154 MHz |
What should your system memory multiplier be?
The multiplier you should use is pretty easy to calculate, as shown below: CPU Multiplier = Maximum Overclocked Processor Speed / Maximum BCLK. So if your maximum overclocked CPU speed was 4.0 GHz and your maximum BCLK was 210, you’d want to set your processor multiplier to 4000 / 210 = 19.05.
