The Clocks tab is intended to simplify the selection of input clock frequencies and the
source of internal clocking signals. For further information regarding clocking and clock
sources, refer to the S1D13506 Hardware Functional Specification, document number
X25B-A-001-xx.
In automatic mode the values for CLKI and CLKI2 are calculated based on selections made
for LCD and CRT/TV timings from the “Panel” and “CRT/TV” tabs. In this mode, the
required frequencies for the input clocks are displayed in blue in the “Auto” section of each
group. It is the responsibility of the system designer to ensure that the correct CLKI
frequencies are supplied to the S1D13506.
Making a selection other than “Auto” indicates that the values for CLKI or CLKI2 are
known and are fixed by the system design. Options for LCD and CRT/TV frame rates are
limited to ranges determined by the clock values.
Note
Changing clock values may modify or invalidate Panel or CRT/TV settings. Confirm all
settings on these two tabs after changing any clock settings.
Note
If the same source clock is selected for use by both CRT/TV and LCD panels, the avail-
able LCD pixel clock selections are limited due to more stringent CRT/TV timings.
