  • Forum Post: PCM1704 specifications

    Kurt G
    I'm really hoping somebody can help me. I need to know the input impedance/capacitance for the inputs of the PCM1704U, particularly BCLK, WCLK and DATA. An IBIS model for this chip would also be extremely helpful. I have checked the datasheet as well as every other resource related to this chip...

    What's the input impedance of this pin? This info is needed for line termination. Thank you.

    I had troubles with PCM1794A, that it doesn't reset after power-up. In datasheet is info, that PCM1794A has internal reset circuit and possibility to use external reset. There are not information, that when I want use only internal reset, I must have externally pulled-up reset pin to VDD or VCC....

    Hello. I need to power this chip from seperate analog/digital supplies. That is, +Vdd,-Vdd,+Vcc,-Vcc will be 4 seperate power supplies. What is the maximum allowable difference in voltage between the digital and analog side? That is, for example, the difference between +Vdd and +Vcc? The datasheet...

    Hello, I'm working with the stereo codec TLV320AIC23B and I can´t manage to get an audio signal at the output. What I get is a DC level. I have configured the device in DAC mode using I2C. It's working as slave. The MCLK frequency is 12.288 MHz, the BCLK frequency is 1.536 MHz and...

    Hello Vikas, I disabled these bits because according to the application note 'Dynamic Behavior of the TLV320DAC23 and the TLV320AIC23B' if OSC is disabled, MCLK still functions. And regarding to the CLK bit, it powers off the CLKOUT pin because we don't need it. Anyway, I also tried...

    Hello Vikas, We have placed the TLV320AIC23B in our own audio board. I have attached the schematic of the circuit, where capacitors S12 y S13 are not mounted for testing. I have one question related to the frequency of BCLK. At the end of page 24 of the datasheet it is said that when the codec...

    Jens Bauer
    Hi, I'm a 'newbie' in this area; currently developing hardware for (and software to control) a PCM1792A. A few questions arose in my mind. 1: Why is the DSD schematic different from the PCM schematic ? - isn't DSD just an input format? 2: What's the max. available sampling...

  • Forum Post: Re: 32bit version of the PCM1792A or DSD1792A

    Jens Bauer
    I agree as well. The S/N virtually eats up the extra 8 bits, but if using two DACs in monoaural mode, one could get a little closer. My guess is that the cool dudes behind the DACs are most likely working on something awesome right now. If not, I'd suggest that they make an 'easy enhancement'...

    Fangyi Chen
    Hi, J Thanks for the reply. I have further questions in using the audio codec to generate a high frequency tone. 1. Sampling points. Despite the Nyquist, a sine wave may have to have more than 10 sampling point to show its shape. A codec dac is usually limited by its relatively low sampling rate...

  • Forum Post: Re: Sampling rate of TLV320AIC3204.

    Fangyi Chen
    Thanks again, J. You seemed to say that as long as the sine wave frequency is lower than 1/2 (Nyquist) sampling rate, there should be no problem. But I would like to confirm this with you again. The reason that I am skeptical about this is my experience with a MATLAB demo. It is in the data acquisition...

    I am interested in using the DSD1792A DAC for an unconventional application. We need to produce a 20-40 kHz sine wave with 120 dB of dynamic range as a feedback signal to a sensor. We want to output the same values of a sine wave (min,max,and zero), but dynamically vary the sampling frequency to change...

    In our DS, we show that we can have -100dB ~ -94dB in Fs:48kHz, Fin:1KHz, 0dBFS. But while our customer uses it, it can only perform -8xB in each channel (based on the schematic of our EVM) and the parameter could not be acceptable. They also use our EVM to do the test but it has the same performance...
