TLV320AIC3100: CODEC IOVDD settings & MCLK input range

Part Number: TLV320AIC3100

Hi,

On my initial development of using TLV320AIC3100, I'm using MCLK input frequency of 19.2MHz with IOVDD of 3.3V as per recommended by datasheet & its functional. On my next phase of design though, I'll require to set IOVDD at 1.8V instead. Can i still use 19.2MHz input frequency at a lower IOVDD such as 1.8V? If yes what are the potential implications & what should i look out for?

Regards,

Leo
