FOC BLOCK: FOCUS SERVO SIGNAL NORMALIZATION
A schematic representation of the FOC circuit is shown in Fig.8.
The normalized focus error signal FEN is based on either 2 or 4 input currents, defined by FEN4/2. If FEN4/2 = 1, then
4 input currents are used. The normalization blocks (N) perform the function described in equation (1) in Section 7.2.2.
An offset can be applied which depends on the state of r/w (to compensate for chromatic aberration in the optics). If
r/w = 1 (read mode) OFR is used. Finally the polarity of FEN can be reversed by setting PFEN = 1. FEN is available on
output D2 if Q/NE = 0. FEN can also be observed via the MON block.
