Note 1: Rs < 10 Ω crystal provides typically a maximum frequency of 40 MHz and Rs<30 Ω a maximum

frequency of 32 MHz. With Rs = 50 Ω crystal the maximum frequency is typically 26 MHz.

Note 2: Crystal Load is at minimum when all CDAC bits are 0s, and at maximum when all CDAC bits are 1s

Note 3: If the Tri State Output Buffer pin is floating (i.e. PD pin is not connected), the Oscillator is in ON state.

IC OUTLINES

Note 1: Also available in AK2140 pin order.

Note 2: MAS9271 pads are round with 80 µm diameter at opening.

Note 3: Pins PV, CLK and DA must not be connected in PXO module end-user application.
