Parameter
Test Method
HA03 Polarity detection
range
(1) Set sub-address (00) data to 40H.
(2) Input signal b (as shown in figure below) to TP16.
(3) Decrease signal b duty from 10% (to shorter negative polarity period) and determine signal b
duty (HDDUTY1) when pin 16 input signal phase no longer locks with that of pin 26 (H-OUT).
(4) Increase signal b duty from 10% (to longer negative polarity period) and determine signal b
duty (HDDUTY2) when pin 24 (FBP IN) phase changes in relation to signal b.
(5) Further increase signal b duty (to longer negative polarity period) and determine signal b duty
(HDDUTY3) when pin 16 input signal phase no longer locks with that of pin 26 (H-OUT).
(6) Decrease signal b duty from 90% (to shorter negative polarity period) and determine signal b
duty (HDDUTY4) when pin 24 (FBP IN) phase changes in relation to signal b.
Duty
= A/B × 100% (0%~100%)
HA04 Sync input threshold
amplitude
(1)
Set sub-address (00) to 82H and TEST mode to 01.
(2) Apply external voltage via 20 k
to pin 14.
(3) Set external voltage to 0 V and monitor pin 14 pin voltage SYNC_TIP_00.
Also check that pin 28 pin voltage is L.
(4) By increasing external voltage SYNC_OFF_00, monitor pin 14 SYNC IN pin voltage when pin
28 DAC1 pin voltage becomes H.
(5) Determine SYNC input level at SYNC separation level 00 as follows:
Vths00 = (SYNC_OFF_00 SYNC_TIP_00) /0.286 × 100
(6) Set SYNC separation level from 01 to 10 to 11, and determine Vths01, Vths10 and Vths11.
Vths01 = (SYNC_OFF_01 SYNC_TIP_01) /0.286 × 100
Vths10 = (SYNC_OFF_10 SYNC_TIP_10) /0.286 × 100
Vths11 = (SYNC_OFF_11 SYNC_TIP_11) /0.286 × 100
