Test Method
Sync block common test conditions
(1) Write data: Transmit PREST DATA. Read data: Read DATA.
(2) Set SW6 to B, SW12 to A, SW16 to B, SW19 to B, SW22 to B, SW23 to B, and SW24 to B, SW28 to B, and
SW29 to B.
A (1) Set SA 00H data to 80H (or 90H).
or (2) Set SW2 to A (or C), SW4 to C (or A), and SW30 to C.
C (3) Input composite video signal of 15.734-kHz horizontal frequency to Y1/SYNC1 IN (or Y2/SYNC2 IN).
(4) Monitor #2 (or #4) pin waveform and #9 (AFC FILTER) pin waveform. Measure phase difference SPH.
(5) Set SW2 to C, SW4 to C, and SW30 to A.
(6) Input signal a to D-SYNC1/Y3 IN.
(7) Set SA 00H data to C4H.
(8) Monitor #30 pin waveform and #9 (AFC FILTER) pin waveform. Measure phase difference DS1PH.
