Version 1.4

Document No.: BRT_000002 Clearance No.: BRT#004

4.2.1

Clock Source

The FT81x can be configured to use any of the three clock sources for system clock:



Internal relaxation oscillator clock (default)



External 12MHz crystal



External 12MHz square wave clock

Figure 4-4, Figure 4-5 and Figure 4-6 show the pin connections for these clock options.

Figure 4-4 Internal relaxation oscillator connection

Figure 4-5 Crystal oscillator connection

4.2.2

Phase Locked Loop

The internal PLL takes an input clock from the oscillator, and generates clocks to all internal circuits,

including the graphics engine, audio engine and touch engine.
