Sync Input Minimum Voltage
Gradually decreasing the amplitude of SG7 in pin 22, measure the amplitude of SG7 when the Sync-Sep output signal
turn off. The value is as SYrv.
Sync Output High Level Voltage/Sync Output Low Level Voltage
Input SG7 to pin 22, read the output high level and low voltage of TP21. The value is as SYVH, SYVL.
Sync Output Rising Time/Sync Output Falling Time
1. The conditions is as table. (SG7 amplitude 0.3 V
P-P
)
This measurement shall use active probe.
2. Measure rising Tri and falling Tfi for 10% to 90% of the input pulse as STr, STf.

Channel Select SW Threshold 1, 2
1. Gradually increasing the voltage of pin 13 from 0 V, measure the maximum voltage of pin 13 when the channel 1 is
selected. The value is as Vthch1.
2. Gradually decreasing the voltage of pin 13 from 5 V, measure the minimum voltage of pin 13 when the channel 2 is
selected. The value is as Vthch2.
Power Save SW Threshold 1, 2
1. Gradually increasing the voltage of pin 11 from 0 V, measure the maximum voltage of pin 11 when the power save
mode. The value is as VthPL.
2. Gradually decreasing the voltage of pin 13 from 5 V, measure the minimum voltage of pin 11 when the power save
mode. The value is as VthPH.
