Hi Diego,
Thanks for the reply.
Can you suggest an alternate to PCM2903C with Industrial grade?
Hi Diego,
I have a requirement of Audio Interfacing where i get digital audio data from processor and o/p will be analog audio.Since my host processor doesn't support any audio control inbuilt(I2S,PCM).I have to go with USB or some other interfacing.
Can you please provide some solution to implement this requirement.
Hi, Anand,
If USB interface is required as the audio interface, I am afraid that we don't have a solution with industrial grade devices. Do you know which other audio interface is available in your host processor?.

Hi Diego
There is no dedicated audio interfacing available from host processor,So only i decided to go with USB approach.
Is there any possibility that i can use SPI or GPIO'S that can be used as interface to audio chip?
Hi, Anand,
If SPI port is available, there is a method used to interface with PCM devices in Left-Justified mode. This method is described in this App Note.
Please take a look, and let us know if this method is suitable for your application. What is the temperature rating you need for your application?, we have some simple codecs with extended temperature range for automotive applications [–40°C to +105°C].
