Microcontrollers for PAL/SECAM TV
with OSD and VST
P8xCx66 family
12 OSCILLATOR CIRCUITRY
The on-chip oscillator circuitry of the P8xCx66 is a single-stage inverting amplifier biased by an internal feedback resistor.
For operation as a standard quartz oscillator, no external components are needed. When using external ceramic
resonators different configurations are supported (see Fig.15). The crystal oscillator operating frequency range is
4 to 12 MHz.
