TLV320AIC3254: Conditions for PLL to lock in slave mode of TLV320AIC3254

yoshiki hasebe

Part Number: TLV320AIC3254

Dear Sirs,

My customer asked about conditions for PLL to lock in slave mode of TLV320AIC3254.

I checked datasheet, but I can't find about above description.

So, please let me know conditions for PLL to lock in slave mode of TLV320AIC3254.

Also please let me know about the tolerance of BCKL when generating PLL from BCKL.

Best Regards,

Hello Hasebe-san,

the Datasheet contains the constraints for the PLL input:

regarding the tolerance of BCLK.... what exactly are you looking for?

best regards,

Hello　Steve-san,

Thank you for your reply.

Customer wants to generate PLL with BCLK, using I2S in Slave mode.

I think PLL_CLKIN in your answer formula is an external BCLK in this case.
Is this correct?

He asks me the frequency tolerance of the external BCLK input.

Best　Regards,

Hasebe-san,

The AIC3254 can use the MCLK, BCLK, GPIO, or MFP1 pins for the PLL_CLKIN

The frequency constraints are in my previous post.

best regards,
