(1)
Set sub-address (00) 0B and (02) 60.
(2)
Input Signal a (33.75 kHz) to pin 21 (SYNC1-IN)
(3)
Measure the sync. tip DC voltage of signal a on pin 21 (SYNC1-IN). (Vsync11)
(4)
Supply external voltage via 100 k
to pin 21 and increase the voltage.
(5)
Measure the sync. tip DC voltage (Vsync12) when HD-OUT desynchronizes with signal a calculate VthS10.
VthS10 = Vsync12 Vsync11
(6)
Set sub-address (00) B1, B2 and B3 and calculate VthS11, VthS12 and VthS13 as well.
(7)
Calculate VthS20, VthS21, VthS22 and VthS23 against pin 19 (SYNC2-IN) in the same way as 4 to 6.
HA05
HD3 input threshold amplitude

Set sub-address (00) 70 and (02) 62.
(2)
Input Signal b (31.5 kHz) to pin 11 (HD3-IN).
(3)
Increasing the voltage of Signal b from 0 V, measure the voltage of Signal b VthHD3 when HD1-OUT lock.
