My dear kind-hearted experts:
Hello,I have some problem needing to be solved, the TPS65951 audio problem, Everyone knows that Tps65951 & Tps65950 a kind of power managing chip. But what is easily be forgotten is it's audio part. There are two parts inputed signal divided left and right ,then routed to A/D and digital interface exchanged by omap3530 then sent the digital data to D/A part of TPS65951, finally the analog signal come out from two parts of output pins:
the first is HSOL :;it's just turn out half of the whole signal,the bottom of the signal is lost,the question made me crazy,please help me solve it. Another qustion is that we haven't any chapter about the configuration.
the second is on board headset Mic: HSMIC.P, HSMIC.M,the signal of output is too low ,we need 4.0V on every point,but it's just 1.0V;Why?
What's more,I have requested the TI china's message centrl with a hopeful mind,But they respond me with some feeling down word. " There are no discribtion about TPS65951's audio ,we just care about the power part of the chip.Audio part comes out of my management,please ask this question to the America experts.in the other hand,we have no EVM board ".
so,I step here to ask American friends for help. What i wanted most was the configuration of the TPS65951 Audio and the EVM board. I'm not sure that you can give me the EVM board, although a little configuration message may help me slove the problem; I felt very difficult when I went though the related chapter named "swca090-Feature differences between TPS65950 and TPS65951" becase of it's details are too bad, some regiser's name not being found. How can i find the difference of the descripton; But In fact, I have configured the TPS65951 by the TPS65950's datasheet due to that there is no TPS65951's configure exited .
My company is located in beijing of china ,we are working for a kind of mobil-phone ,If you can slove my problem ,I will buy 100 thousands pills chip from IT.
