Part Number: PCM4220 Tool/software: Hello
Can the Master Clock (MCKI) and DSP clock use different clock sources which are not phase linked?
MCKI will be 12.8MHz from a low power, low jitter MEMs oscillator.
The DSP will communicate with the PCM4220…
Part Number: PCM4220 I cannot get the OVFL and OVFR to go HIGH.
I connected a 7.5Vpp differential signal, 20kHz, on its input and OVFL/R do not go HIGH.
7.5Vpp is the maximum do to my input op-amp.
I have setup the ADC for 200kHz sample and the…
Part Number: PCM4220 Hi,
I am using multiple PCM4220 ADCs and need to be able to trigger them so that their conversions happen at the same time.
Is this possible?
Thanks

Part Number: PCM4220 I am using the PCM4220 with a 12.8MHz master clock in order to generate 200kHz sample rate. The part is specified up to 216kHz.
The device is operating in master mode. See the attached schematic.
The device is expected to run…
Part Number: PCM4220 Other Parts Discussed in Thread: PCM4202
During testing of a design based around the PCM4220 there has been a spurious tone seen in the digital data that seems to be generated internally by the ADC. The PCM4220 is being run in Quad…
Part Number: PCM4220 Hi TI Team,
When the temperature of PCM4220 reaches 60 degrees, PCM4220 makes noise. Reduce the temperature of PCM4220 to 25 degrees and return to normal. Please help to analyze the reason, thank you!
Part Number: PCM4220 Other Parts Discussed in Thread: PCM4222 Hi team,
We meet some issues regarding THD+N of this part.
In datasheet, it shows THD+N is -10xdB at 997Hz, -1dB input and -9xdB at 997Hz, -20dB input no matter which sample rate is used…
Part Number: PCM4220 Other Parts Discussed in Thread: PCM4222 When increasing the Vcc of the PCM4220 (to eliminate idle tones as per another thread on E2E), does the maximum input voltage range of the PCM4220 also change? I expected with the internal…
