Part Number: PCM1754 Other Parts Discussed in Thread: PCM1753 Hello,
Our customer found -100dB 5KHz-6KHz tone noise at no-signal input at 192KHz fs.
When input -60dB 1KHz signal, this tone noise is disappeared, and -90dB it become identified.
Furthermore…
Part Number: PCM1754 Hey all, I was on this forum searching for "PCM1754 noise" and everything pointed to layout issues, grounding and decoupling. Although I had this exact issue seen in some posts, my resolution was none of the above.
At the…
Part Number: PCM1754 Other Parts Discussed in Thread: PCM1681 , Hello Professional, My customer observed following behavior with PCM1754 and PCM1681. Each output channel have different mid-scale output voltage(observed 2.3V~2.6V) when BCK or LRCK is halted…

Dear TI FAE,
I'm working on a project using PCM1808 and PCM1754. Partial schematics and layout below. The goal is to replace an existing codec with these ADC and DAC, on a…
Part Number: PCM1754 Hello,
Our customer is trying to replace the DAC to PCM1754.
During their ES sample evaluation, they found unstable noise floor level at more than 20KHz non audible band.
It seems “Delta Sigma modulator” create noise shaping characteristics…
