Notes about vertical section
Note 10: Value of acceptable cumulated parasitic load resistance due to humidity, AGC storage capacitor leakage, etc.,
for less than 1% of Vamp change.
Note 11: The threshold for VVOB is generated internally and routed to VOscF pin. Any DC current on this pin will
influence the value of VVOB.
Note 12: Maximum of deviation from an ideally linear sawtooth ramp at null S-correction (
SCOR at 0000000b) and null
C-correction (
CCOR at 1000000b). The same rate applies to V-drive signal on VOut pin, no effect on EWOut.
Note 13: Maximum S-correction (
SCOR at x1111111b), null C-correction (CCOR at 1000000b).
Note 14: Null S-correction (
SCOR at 0000000b).
Note 15: "tVR" is time from the beginning of vertical ramp of V-drive signal on VOut pin. "TVR" is the duration of this ramp,
see Chapter 7 - page 22 and Figure 19.
Note 16: If VVEHT=VVEHTnull or VHEHT=VHEHTnull, respectively, the influence of VVEHT on vertical drive amplitude
or the influence of VHEHT on EW drive signal, respectively, is null.
Note 17: VVOamp = VVOT -VVOB
Note 18: Only the top of the saw tooth drifts. The same rate applies to V-drive signal on VOut pin.
Note 19: Informative, not tested on each unit.
Note 20:
VSIZE at medium value 1000000b.
Note 21:
VPOS at medium value 1000000b.
Note 22:
VPOF at medium value 1000000b.
Note 23:
VSAG at maximum value 1111111b.
