Part Number: PCM4222 Tool/software: Hi,
I have designed a functional test (FT) board using the PCM4222, with a total of 4 sites, each equipped with one PCM4222. I’ve encountered an issue where using the ADCs simultaneously causes interference between…
Part Number: PCM4222 Tool/software: Is an external RC (10000pF and 10kOhm) needed for a simple power on reset circuit external to the PCM4222. I have no microprocessor or reset switch on the design. If an external RC is needed then do I need to use schmitt…
Part Number: PCM4222 Tool/software: Hello,
page 26 of the PCM4222 datasheet says the PCMEN pin should be high for MBM output mode, but page 16 of the PCM4222EVM Users Guide says the PCMEN pin should be LO in MBM output mode.
Could someone clarify the…
Part Number: PCM4222 hi,
PCM4222 work in PCM mode and sclk=12.288Mhz, normal mode. sample rate is 48khz.
below is my design that produce P/N diff signal to PCM4222 analog input.
when below PCM4222_P/N port not connected to PCM4222 analog input, THD is…
Part Number: PCM4222 Hi,
I checked the PCM4222s datasheet but did not find a specification for the power supply rejection ratio of the IC (VCC1 and VCC2). Are these values specified elsewhere or could you please provide these numbers?
Thanks, Stepha…
Part Number: PCM4222 We are using this part in a measurement system for precision audio measurement. We are trying to bound limits of measurement change between calibration procedures. However the data sheet for the part doesn't have any temperature coefficient…
Part Number: PCM4222 Other Parts Discussed in Thread: OPA1632 Hi, I am implementing the PCM4222 in a design and i have a question in respect to the maximum analogue input voltage on pins VinL+/VinL- and VinR+/VinR- for FSD. The datasheet states on page…
Part Number: PCM4222 Hello,
About the THD+N, I have a question to interrupt you.
The dynamic range is about 121dB, that is to say the ADC quantized noise is about-121dbfs. But when the sample rate is 48Khz and 96Khz, the THD+N are both 108dB under the…
