×
(DCLK/CLKi). The unit for CLKi
and DCLK is MHz. When CLKi=2
×
DCLK, use a clock with which CLKi and DCLK are
synchronized. CLKi is CLK0 when multiplication is not performed, and N
×
CLK0 when
multiplication is performed with a multiplication factor of N.
4. In interlace and interlace sync & video modes, the setting is: VDS8–0
≥
1.
5. Use a value of 4 or more for DSX.
6. When the
EXHSYNC
cycle is an even multiple of CLK1
7. When the
EXHSYNC
cycle is an odd multiple of CLK1
