ICs for CD/CD-ROM Player
AN8806SB
BDO Detection
BDO is detected by the low speed detection circuit and high speed detection circuit. The high speed detection circuit is
incorporated. On the other hand, the capacitor of the low speed detection circuit must be connected to Pin13. The capacity value
is 2200pF and it is recommended that it should be connected for V
CC
. When this capacity value of Pin13 is increased, BDO is
detected with large RF missing rate. When it is decreased, BDO can be detected with small RF missing rate.
OFTR Detection
OFTR detection reversely corresponds with BDO detection. However, its detection method is the same as for BDO. Capacitor
for the low speed detection must be connected to Pin15. It is recommended that it should be connected to V
CC
at 2200pF in the
same way as for Pin13. The relation between the capacity value and OFTR detection timing is as the same for BDO.
BDO present = H
BDO absent = L
OFTR = H
Off from OFTR = L

Reference Supply
Servo reference supply is incorporated. Pin20 outputs V
CC
/2, and has approx. 3mA of current capacity for sink/source. It is
recommended that it should be given 1
μ
F to 10
μ
F of capacity in addition.
By connecting Pin4 to OPEN or GND, the reference voltage of LD can be switched. Connection to OPEN makes the reference
voltage approx. 170mV and connection to GND makes it approx. 140mV.
Vibration Detection
The AN8806SB has a wind comparator of approx.
±
75mV. Abnormal vibration components of tracking error are detected and
the data for whether vibration is present or not is outputted to Pin22.
