ADAU1996A Crystal Specification

Hi All

I am designing a board which has an ADAU1966A and I've noticed the crystal spec is nothing but vague.

What is the spec for the crystal.. PPM requirement?  Load Capacitors? ESR?

I am actually looking at a CX3225SB12288H0FLJCC: 15 ppm, 12pF, 150R for the required temperature range but calculating the component values with the info in the datasheet is challenging to say the least.

Thanks in advance
