1.4 POWER SUPPLY AND LOADING BLOCK
The VD (8.3 ± 0.5V), the VD2 (5.6 ± 0.5V) and the VDD (5.0 ± 0.25V), which are supplied from the mother PC board, are
used for the power supply. In this system, the following four power-supply signals are available: the VD (for the drive
system), the V3R3 obtained from the VD2 via the 3.3V regulator (for the control system: 3.3V), the VDD (for the micro-
computer: 5V), and the 3VDD obtained from the VDD via the 3.3V regulator (for the microcomputer: 3.3V).
In the WMA-supported mechanism CXK5661, the V2R5 obtained from the VD2 via the 2.5V regulator (for WMA
decoder: 2.5V) is also used.
The microcomputer can turn on/off the CD driver (except for the load and eject modes) and the 3.3V signal by control-
ling the "CONT" and "CD3VON" signals respectively. To turn on/off the loading drive, there is no control terminal in the
microcomputer, but the "LOEJ" input signal works as the control one. In the LCO output block, the "CLCONT" signal is
used to switch between the loading mode and carriage mode.
