Part Number: PCM1774 Hi I am using an STM32F7 for audio playing via I2S directly to the PCM1774. It's working perfectly for 20 second and after I get for 4 second an audio with noise. This noise it's came periodically after each 20 second for 4 second…
Part Number: PCM1774 Hi,
I am using the PCM1774 audio DAC for a wearable device and I would like to confirm the schematic for Line output instead headphone.
- Do I need to add a resistor of 10K to the HPOL and HPOR for impedance matching because the RL…
Part Number: PCM1774 Hi,
My customer is trying setting clock frequency as below;
SCLK: 8MHz, FS:31.25kHz, BCLK:1MHz
BCLK/FS=32 in this case.
However, there is no "32" in BIT CLOCK BCK ot table 9/10 on the datasheet.
Does it mean that this setting…
Part Number: PCM1774 Hi,
The default value of NPR and MSR is "0" as below;
On the other hand, All "0" data is nothing on the table9 of the datasheet.
Does it mean that internal PLL is disabled on the default condition?
Best Regards…
Part Number: PCM1774 Hi,
my customer uses two PCM1774 and has the following questions:
Reading the datasheet I was not able to found a register that configure the PCM1774 output as a line output (load > 10k Ω ) or a Headphone output (load 16 Ω or 32 Ω …
Part Number: PCM1774 Good morning,
I am currently doing my master thesis in TU Delft and I was thinking of using the PCM1774 as a dual audio DAC to convert the audio data coming from a mini SD card through the microcontroller BeagleBone Black. Do you…
Part Number: PCM1774 Hi :)
My customer wants to use PCM1774 an they do have some questions, maybe you can help.
They would not use AIN1L and AIN1R.
1: What is the recommendation for this two inputs ?
2: is there a recommendation for Ground connections…
Part Number: PCM1774 Hi!
my customer uses PCM1774 and has the following questions:
------------------------------------------------------------------
PCM1774 is used associated with a Silicon Lab CP2114.
The CP2114 generates 3 clocks to the PCM1774. …
Part Number: PCM1774 Other Parts Discussed in Thread: PCM1771 , PCM5102A Hello,
This time, there is Customer who has evaluated PCM1774 as an alternative to Asahi Kasei AK4352. The AK4352 communicates with the microcomputer by using the attached 0: 16bit…
