6.8 Clock Options
S5U13704B00C Rev. 2.0 Evaluation Board User Manual
Issue Date: 2002/09/16
The input clock (CLKI) frequency can be up to 50MHz for the S1D13704 if the internal
divide-by-2 mode is set. If the clock divider is not used, the maximum CLKI frequency is
25MHz. There is no minimum input clock frequency.
A 6.0MHz oscillator (U2, socketed) is provided as the input clock source. However,
depending on the LCD resolution, desired frame rate and power consumption budget, a
lower frequency clock may be required.
A jumper, JP7 is provided to allow CLKI input to be the same as BCLK input, for systems
in which is desired to use only one clock signal for both BCLK and CLKI.
The bus clock (BCLK) is selectable and can be provided by a 50MHz oscillator (U7,
socketed) or the host CPU (for non-PCI host).
