Note 1: MAS9270 pads are round with 80 µm diameter at opening.
Note 2: Pins CLK and DA can either be connected to VSS or left floating, pin PV can either be connected to
VDD or left floating and pin TE1 must be left floating in VCTCXO module end-user application.
Note 3: Die map reference is the actual left bottom corner of the sawn chip.
