14 CLOCK SYSTEM
14.1 Clock generation circuit
The internal CGC generates the system clocks LLC, LLC2
and the clock reference signal CREF. The internally
generated LFCO (triangular waveform) is multiplied by 4
via the analog PLL (including phase detector, loop filter,
VCO and frequency divider). The rectangular output
signals have a 50% duty factor.

14.2 Power-on control
Power-on reset is activated at power-on, chip enable, PLL clock generation failure and if the supply voltage falls below
2.7 V. The RES signal can be applied to reset other circuits of the digital picture processing system.
Fig.27 Power-on control circuit.
CE = chip enable input; XTAL = crystal oscillator output; LLCINT = internal system clock;
RESINT = internal reset; LLC = line-locked clock output;
RES = reset output (active LOW).
