Explanation for circuit operation
2) CD0031AM
This converts the digital convergence waveform to analog waveform as a 6-channel, 16 bit D/A
converter IC for digital convergence.
The features of this IC are as follows.
High Sampling Rate Operation : 1MHz
Differential Non-Linearity Error : +/- 1 LSB
=> Operate on 1H to Over 3H Application
Center Voltage Output
=> Same Electrical Characteristics of Center Voltage Output and RH, GH, BH, RV, GV, BV’s
Zero Cord Outputs
Mute Function
3) Others
3-1) KF353
This is used as a level shift and low pass filter (1506-1511) of RH, GH, BH, RV, GV and BV.
3-2) STK392-020 (1940, 1905)
This uses a 3 channel AMP to apply RH, GH, BH, RV, GV and BV via level shift and low
pass filter (1506-1511)to a Sub-DY coil.
