∗ The HD of this chart indicates the actual CXD2498R load timing.

∗ The numbers at the output pulse transition points indicate the count at the MCKO rise from the fall of HD.

∗ The HD fall period should be between approximately 2.8 to 12.0µs (when the drive frequency is 22.5MHz). This chart shows a period of 115ck (5.1µs). Internal SSG is at this timing.

∗ SUB is output at the timing shown above when output is controlled by the serial interface data.

∗ Frame shift of V1A/B/C, V2, V3A/B/C and V4 is performed up to 90H 2864ck (#250) in the A Field of frame mode (center scan 1), 44H 2864ck (#250) in the B Field, 99H 1570ck

(#369) in the A Field of frame mode (center scan 2), 53H 1570ck (#369) in the B Field, 32H 2864ck (#250) in progressive scan mode (center scan 1), and 46H 1646ck (#369) in

progressive scan mode (center scan 2).
