Notes:
Note (1): Specifications are tested 100% or
guaranteed by characterization.
Note (2): All specifications are valid for Manchester
and Biphase encoding, and for 2kbaud and 4kbaud
data rate options.
Note (3): Maximum supply voltage is generated by
forcing 10mA between coil and ground pin.
Note (4): Min = Vbottom (modulation on),
Note (5): Modulation depth is calculated as Vachigh -Vaclow / Vachigh + Vaclow. Lower modulation depths may
be applied, but the performance of the system may vary along the distance between reader and transponder coil.
Higher modulation levels will reduce the maximum Write distance.
Note (6): Lot to lot spread on capacitance is 20%. Temperature shift is typically 0% on -40 C, and +1% at 85 C.
Max = Vtop (modulation off).
