ICs for CD/CD-ROM Player
AN8807SB
The VCBA is for focus balance adjustment. Connecting 47k
of external resistance toPin299, signal ratio between A+C and
B+D can be controlled as shown in Table 1.
Tracking Error Amplifier
As shown in Figure 3, the tracking error amplifier receives the output currents E and F of three-beam method pin photo diode
for sub-beam detection, and outputs the operation result of E–F to TEOUT (Pin25).
