TEST CONDITION (VCC = 9V, Ta = 25±3°C)
MEASUREMENT METHOD
(1) Measure vertical ramp amplitude when the data of sub-address (09) is set (3F).
(VVH)
(2) Measure vertical ramp amplitude when the data of sub-address (09) is set (00).
(VVL)
(1) Apply white 100% signal that has short sync. every 10H to pin 39.
(2) Observe sync. separation output at pin 31.
Measure sync. separation level by changing sync. length.
83 Forced V. Osc. (262.5H)
â â (C0)
(1) Set the data of sub-address (0A) to (C0).
(2) Measure vertical frequency at pin 22.
