Part Number: PCM1863 Hi team,
Can you please review this schematic (will send internally)?
This is for an AK5522 replacement.
They are using a Master clock of 12.2888Mhz, and they are going to use 16KHz as the sampling rate, which means they will need…
Part Number: PCM1863 Hi Team,
Our customer is looking for an audio ADC device similar to PCM1863 but with 4 ADCs and 2 separate I2S outputs so that he could choose 2 separate outputs from the 4 inputs. Upon checking our product lines it seems that we don…
Other Parts Discussed in Thread: PCM1863 Clarification please : what is the effect of leaving "unused" analogue inputs floating vs terminating to GND through a cap. To my knowledge, both could be valid depending upon chip-internal circuitry. …
Part Number: PCM1863 Hi team, I got a question from customer. We have an external 12.288MHz clock that feeds into the PCM1863 at SCKI pin. PCM1863 is controlled via I2C and operates in slave mode with 16KHZ fs, DVDD and IOVDD both at 3.3V, we are wondering…
Part Number: PCM1863 We're trying to source a 24.576 MHz crystal to use with the PCM1863. The datasheet appears to be silent on things like required tolerance, drift and ESR. Is that info available?
Thanks, Scott
Part Number: PCM1863 Hello,
In the data sheet I see no specification for the minimum Energysense threshold. However, the EVM only allows you to set it to -57dBFS. I want to set it to -72dBFS; however, I notice that i get constant interrupt triggers when…
Part Number: PCM1863 Other Parts Discussed in Thread: HDC1080 Hi Team,
We are using PCM1863 part in our custom linux board for collecting audio samples from stereo analog mics.
The main processor is based on ARM Cortex A7 running linux. We have custom…
Part Number: PCM1863 Other Parts Discussed in Thread: NE5532 Hello,
I am using a Birt differential circuit in front of the CPM1863 and thus have a good location to inject a CM voltage. This would remove the need to AC couple my signal twice which has benefits…
Part Number: PCM1863 Hi Sir,
Is it suitable that use PCM1863 PGA gain as the preamp gain for the microphone which sensitivity is about -30 ~ -40dB and 60dB SNR, single-ended?
Take a microphone with -35dB sensitivity/60dB SNR to be considered and our target…
