PCM1860: Can We Use 1.8V MCLK (SCKI) for PCM1860?

Wayne Chen (Audio AE)

Part Number: PCM1860

Hi Sirs,

As title, can we apply 1.8V MCLK (SCKI) to the PCM1860 when using 1.8V VDDIO?
The datasheet specifies 3.3V CMOS level in the description of SCKI.

Thank you and Best regards,

Hi Wayne,

Take a look at table 4, page 35. You need a 3.3V clock source on SCLK, 1.8V IOVDD is OK in this condition for the PCM1860.
