CXA1782CQ/CR
Tracking Error Amplifier
The photo diode currents input to E and F pins are each current-voltage converted by the E I-V and F I-V
amplifiers.
The CXA1782 tracking block has built-in circuits for balance and gain adjustments to enable software-based
automatic adjustment.
The balance adjustment is performed by varying the combined resistance value of the T-configured feedback
resistance at E I-V AMP.
F I-V AMP feedback resistance = R
F1
+ R
F2
+ R
E I-V AMP feedback resistance = R
E1
+ R
E2
+ R
Vary the value of R
E3
in the formula above by using the balance adjustment switches (BAL1 to BAL3).
For the gain adjustment, the TE AMP output is resistance-divided by the gain adjustment switches (TOG1 to
TOG3), and it is output at Pin 42.
These balance and gain adjustment switches are controlled through software commands.
