Note 10: Value of acceptable cumulated parasitic load resistance due to humidity, AGC storage capacitor leakage, etc.,
for less than 1% of
V
amp
change.
Note 11: The threshold for
V
VOB
is generated internally and routed to
VOscF
pin. Any DC current on this pin will
influence the value of
V
VOB
.
Note 12: Maximum of deviation from an ideally linear sawtooth ramp at null
SCOR
(Sad09 at x0000000b) and null
CCOR
(Sad0A at x1000000b). The same rate applies to V-drive signal on
VOut
pin.
Note 13: Maximum
SCOR
(Sad09 at x1111111b), null
CCOR
(Sad0A at x1000000b).
Note 14: Null
SCOR
(Sad09 at x0000000b).
Note 15: "t
VR
" is time from the beginning of vertical ramp of V-drive signal on VOut pin. "T
VR
" is duration of this ramp, see
chapter
