X- Drive Block
The X- Drive PCB receives X – Drive signals from the Digital Video
Assembly's drive sequence generator. The X – Drive signals ( XSUS
up, XSUS down, XSUS B plus and XSUS ground are sent to the
logic block. The four signals are sent out in parallel to the upper
and lower sustain pulse generators. The drive signal output from
the sustain pulse generators are controlled by reset and mask
FET's shown in each block to obtain the Panel Sustain signal sent
to the upper and lower X connector assembly's. This module also
contains a DC to DC converter and over current detect circuits.
