Hi,
Could you please clarify why the USB differential interfaces (D+ and D-) are necessary for data transmission to the chip? Is it not possible to connect directly to the DAC or ADC inputs/outputs? Does this relate…
Hi Ena,
USB Audio is not very demanding so most microcontrollers should be able to handle it in place of the TAS1020B.
Our newer AC-MB cards which control most newer EVMs use an XMOS EF216-512-TQ128-C20 in place of the AC-MB. For a TI solution I recommend…
Part Number: PCM2906C Other Parts Discussed in Thread: TUSB4041I , Tool/software: Hi TI team members,
Im designing an USB Audio Card with multiple Input/ouput channels ( 8 mono inputs and 8 mono outputs, with Analog and Digital SPDIF I/F).
Checking TI…
Part Number: PCM2906C Hi,
The datasheet states that the analog performance of the ADC may be degraded when using an internal voltage regulator.
It seems that the internal voltage regulator turns off when power is supplied externally to the VCCCI pin…
Part Number: PCM2906C Hi,
Our customer designed the circuit shown in the diagram below, fabricated a prototype board, and evaluated it. When operated by applying 5V from the PC (USB), the PCM2906C generates abnormal heat. (Although I have not specifically…
Part Number: PCM2906C Hi,
Our customer is considering this product for the purpose of importing analog signal waveforms to a PC via USB (not for playing music). Therefore, it is assumed that HID0~2 will not be used. I understand that HID0~2 should be Low…
Part Number: PCM2906C Other Parts Discussed in Thread: PCM2903 , The customer is considering to choose PCM2906C or PCM2903.
The customer find the below three advantages of PCM2906C.
1. The 2906 can use the internal 3.3V LDO as the power supply for VCCI…
Hi Andrew,
We managed to get our original solution with the PCM1808 (24-bit, 48kHz I2S) and DIT4096 in HW mode to work with the PCM2906C S/PDIF input. The issue was the copyright bit (bit 2) in the S/PDIF channel status data, which needed to be logic…
Part Number: PCM2906C Hi Team,
The datasheet mentions that VCCCI is an internal analog supply so I'm wondering why an LDO is added in Figure 36 of the datasheet.
It says this is a configuration for "High-Performance Application", so is it true that…
