DCLK

Dot Clock / Pixel clock. This clock supplies the display controller, the video pipeline, the ramdac,

and the TV output logic. Its value is dependent on the selected display mode.

Its frequency can be as high as 135 MHz. This signal is either driven by the internal PLL to a minimum of

8MHz or by an external oscillator. The direction can be controlled by a strap option or an internal register

bit.
