[1] optimal means that the lc product (l of am coil and c of c-bank) has zero tc1, since tc1(c-bank) = +50 ppm/k. having tc1(l of am coil) equal to - 50 ppm/k is not a hard requirement. however, it is advisable to keep the tc1(lc product) < 350 ppm/k. 13.1.2 am coil alignment alignment is setting the right c-align value and tuning the am coil. this is done as follows: 1. set c-align = 0 2. measure the resonance frequency 1 (f rsn1 ) with c-bank = 0 3. measure the resonance frequency 2 (f rsn2 ) with c-bank = 122 4. set c-bank = 0: C tune c-align until the resonance frequency 3 becomes f rsn3 C tune am coil until the resonance frequency 4 becomes f rsn4 the f rsn3 and f rsn4 values can be calculated based upon f rsn1 and f rsn2 . this procedure only has to be done once in order to ?t the am coil and device together. the c-align data has to be stored in the microcontroller and should be written every time the device is powered up. for c-align the internal digital controlled capacitor is used in principle. it is also possible to use an external trim capacitor (0 pf to 17 pf) instead. this has the advantage that no alignment data has to be stored in the microcontroller at the cost of one trim capacitor. table 47. am coil requirements parameter value nominal value 203 m h tuning range needed for alignment (excluding own tolerance) 16 % optimal tc1 [1] - 50 ppm/k
