TEST CONDITION (V_CC = 9V, Ta = 25±3°C)
MEASUREMENT METHOD
(1) Apply Sync. signal to pin 39.
(2) Observe horizontal output at pin 32.
Change the input sync. frequency by 10Hz step up to ±3kHz.
Measure the pull-in range.
(1) Apply Sync. signal to pin 39.
(2) Observe input sync. signal and pin 33.
Measure the pull-in stop period as follows.

76 Horizontal Sync. Position ↑ ↑ ↑ OFF
Adjustment
(1) SW₃₀ is on, and delay the rising of FBP from rising of horizontal out by 1µs step.
(2) SW₃₀ is off. Measure the maximum delay time which AFC2 can pull-in.
(1) Measure the phase of horizontal out when the data of sub-address (05) is set
(10).
(2) Measure phase change when the data of sub-address (05) is change to (00) and
(1F).
