Evaluation Board for AK8125A AKD8125A-miniEva 1. Description 3. Configuration AKD8125A-miniEva-Y is a common evaluation board and can produce a center or down spectrum spreading output with pin-selectable modulation ratio. AKD8125A-miniEva-Y has three footprint types for crystal unit. The AKD8125A-miniEva-Y allows the user to set all function for AK8125A by 0[Ω] chip resisters. The modulation mode and the modulation ratio are selectable by the state of the SS_SEL[1:0] pins. The operation frequency range applying to the board is required to select by the state of the F_SEL[1:0] and OUTMPX pins. 2. Ordering Information AKD8125A-miniEva-Y allows the user to choose a device type and a crystal unit.
