Dynamic Convergence Ic701 - Sony CPD-420GS Training Manual

Dynamic Convergence IC701

The DSP IC1002/8 (YDC) outputs the complex convergence waveform
and is routed to the D Board. The YDC signal is input to IC701/2 (+IN B).
IC701 current amplifies the YDC signal and the output at pin 1 (OUT B) is
applied to the convergence yoke. When the Dynamic Convergence ad-
justment is performed, IC1002 varies the DC reference level, shape and
size of the YDC signal. The YSC signal is applied to the convergence
yoke to shift the R and B beam landing in the horizontal direction in the
outer areas of the CRT.
The DSP IC1002/6 (XDC) outputs the complex convergence waveform
and is routed to the D Board. The XDC signal is input to IC701/5 (-IN A).
IC701 current amplifies the XDC signal and the output at pin 6 (OUT A) is
applied to the convergence yoke. When the Dynamic Convergence ad-
justment is performed, IC1002 varies the DC reference level, shape and
size of the XDC signal. The XDC signal is applied to the convergence
yoke to shift the R and B beam landing in the vertical direction in the outer
areas of the CRT.

The DSP IC1002/7 (DCC) output is routed to the D Board to provide IC701
pin 3 (+IN B) and pin 4 (+IN A) with a DC bias voltage offset (REF DC).
The Micro IC1001/7 'REMOTE ON/OFF' output is routed to the D Board
and is input to IC701/11 (STBY) to mute the outputs of IC701 when in the
'Active Off' and 'Standby/Suspend' modes.
