* The volume control is not accessible through SPI connection.* Why? The PCM2707 datasheet states: ================================= Table 8. SPI Register Field Descriptions : D6 Reports volume-up HID status to the host (active high) D6 Reports volume-up HID…
Other Parts Discussed in Thread: PCM2706 , PCM2705 Hello! The PCM2706 (C), PCM2707(C) DAC ICs can control the USB host with the 7 commands like PLAY/PAUSE, Vol.+/-, NEXT TRACK, etc. What is necessary to control playing modes if the USB host is considered…
Hi Takumi-san,
Q1)
That's correct, PCM2xxxC changes the descriptors and the volume control, in addition PCM2xxxC are certified in Win7. PCM2xxx are able to work on Win7, too, but these are not certified.
Q2)
PCM270x are DAC while PCM290x are COD…
Other Parts Discussed in Thread: PCM3070 , TPA3123D2 , PCA9535 , PCM2705 Hi,
We have designed a Soundbar using RDK value SB as a reference. After successfully programming the PCM3070 and MSP430 the MSP430 is failing to boot up the PCM3070 which in turn we…
Other Parts Discussed in Thread: PCM2704 In our current design PCM2705DB chip is going to be used as the standalone USB to S/PDIF Converter device only.
No analog outputs and external custom descriptors EEPROM will be used.
The device supply is in the…
Faizan,
Awesome! And I couldn't find any specific app notes at this time, but the capacitor recommendation can be made in general. Long traces induce stray inductance, which can cause issues in various forms. No vias and short traces with capacitors…
