May I know what we need to config TAS5508C by I2C when sampling rate changed ?
Will TAS5508C automute output PWM during input MCLK/BCLK/FS dis-continue ?
Actually we hear pop noise when different source(FS) switched.
Thanks in advance !
the guy who needs to work on this is out until Monday. I apologize for the delay.
have you seen our latest parts in this family? Tas5548 and tas5558?

Yes ! I know TAS5548/58 with ASRC function. Released in end of 2012.
Pls kindly give suggestion of TAS5508C . TKS !
When Fs changes, the device automatically adapts to the new Fs. You don't need to write anything on I2C. However, you may want to change register 0x03 bit D4 to soft mute on recovery from clock error during the initialization. The pop depends on the power stage more than the modulator (TAS5508C). If you have single-ended configuration on the power stage, the pop may be audible.

In reply to Tuan:
We already test this register bit and can see some improvement but no for all PCBA.
My post stage was LPF + DRV632 line out to sub-woofer.
May I know what's PWM behavior when apply new Fs ?
How fast TAS5508C PLL could lock new Fs ?
Any electrical character to describe "soft unmute" this register bit ?
Many thanks your help !
