37 / 47 page TA1383AFG 2005-09-05 37 SW Mode Note No. Characteristic SW2 SW4 SW9 SW30 Test Method SY11 AFC phase detection current C C OPEN C (1) Set SA 00H to C0H and SA 02H to A0H. (2) Set SW9 to open and measure #9 voltage V9 (6.3 to 6.4 V) (measure #9 voltage at no load). (3) Connect external power supply (PS) to TP9 and apply V9. (4) Set SW30 to A. Input 15.734-kHz sync signal d to D-SYNC1/Y3 IN. Monitor #9. Measure voltages V1 and V2. (5) Set SA 02H data to C0H. Repeat steps (2) to (4) above. Measure voltages V3 and V4. (6) Set SA 02H data to 80H. Connect external power supply (PS) to TP9 and apply V9 − 0.1 V and measure voltage V5. (7) Connect external power supply (PS) to TP9 and apply V9 + 0.1 V and measure voltage V6. (8) Determine ID1 to ID6 using following equations. ID1 + = (V1 [V] ÷ 1 [kΩ]) × 1000 [µA] ID1 − = (V2 [V] ÷ 1 [kΩ]) × 1000 [µA] ID2 + = (V3 [V] ÷ 1 [kΩ]) × 1000 [µA] ID2 − = (V4 [V] ÷ 1 [kΩ]) × 1000 [µA] ID3 + = (V5 [V] ÷ 1 [kΩ]) × 1000 [µA] ID3 − = (V6 [V] ÷ 1 [kΩ]) × 1000 [µA] Signal d #9 Pin Waveform 63.5 µs 4.7 µs V1, V3, V5 V2, V4, V6 0.286 V |
