Input SG2 (0.35mVp-p) to TP22 and
read the gain transition points of the
non-inverted output at TP12 when
level of the input signal.
Measure the COM output DC voltage
when COM-DC = 00h and 7Fh, and
measure the difference from the
COM output DC voltage when
COM-DC = 40h.
Input SG4 to TP18, TP19 and TP20,
gradually raise the high level from
0V, and assume the high level
voltage at which the output level
goes to BLK-LIM level as Vth1OSD,
and the high level voltage at which
the output goes to WHITE-LIM level
as Vth2OSD.
SEN setup time, activated by the
rising edge of SCK. (See Fig. 3.)
SDAT setup time, activated by the
rising edge of SCK. (See Fig. 3.)
SEN hold time, activated by the
rising edge of SCK. (See Fig. 3.)

SCK pulse width. (See Fig. 3.)
SEN pulse width. (See Fig. 3.)
Measure the transition time of each
output.
90pF load: HST output pin
120pF load: HCK1 and HCK2 output
(See Fig. 1.)
Measure the transition time of each
output.
50pF load: DWN, WIDE, VCK, VST,
(See Fig. 1.)
Measure HCK1/HCK2.
120pF load
(See Fig. 2.)
Measure the HCK1/HCK2 duty.
