Characteristics
Test Conditions
HA03 Polarity detection
range
1.
Set subaddress (00) data to 40H.
2.
Input signal B (as shown in the figure below) to TP50 pin.
3.
Decrease signal B duty from 10% (to shorter negative polarity period) and measure signal B
duty (HDDUTY1) when #50 input signal phase no longer locks with that of #37 (H-OUT).
4.
Increase signal B duty from 10% (to longer negative polarity period) and measure signal B duty
(HDDUTY2) when #39 (FBP input) phase changes in relation to signal B.
5.
Further increase signal B duty (to longer negative polarity period) and measure signal B duty
(HDDUTY3) when #50 input signal phase no longer locks with that of #37 (H-OUT).
6.
Decrease signal B duty from 90 % (to shorter negative polarity period) and measure signal B
duty (HDDUTY4) when #39 (FBP input) phase changes in relation to signal B.
Duty
= A/B × 100% (0 to 100%)
HA04 Sync input threshold
amplitude
1.
Set subaddress (00) data to 82H, and TEST mode to 01.
2.
Connect variable power supply to #53 via 20-k
resistor.
3.
Set variable power supply voltage to 0 V, and measure #53 voltage. (SYNC_TIP_00) Also
check that #34 voltage is set to Low (GND level).
4.
Increase variable power supply voltage so that #34 voltage becomes High (VCC level).
Measure #53 voltage. (SYNC_OFF_00)
5.
Calculate the following equation to determine SYNC input separation level at SYNC separation
level is 00. VthS00 = (SYNC_OFF_00 SYNC_TIP_00)/0.286 × 100
6.
Change SYNC separation level to 01, 10, and 11. Calculate following equations to 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
