Preliminary
PLL of the KB2502
PLL is composed of the phase detector, charge pump, VCO, and N-divider as 4 sub-blocks.
The following is the description of the input/output signals.
-
HFLB (Input)
Horizontal flyback signal is refrence signal of the PLL built in KB2502.
The HFLB signal's frequency range is 15 ~ 90kHz, so the PLL block must be a wide range PLL that can cover
HFLB's entire frequency range.
- VCO (Input)
Error signal that passes through an external loop filter is input into VCO.
Operation voltage range is 1-4V. You can raise immunity towards external noise by lowering VCO
sensitivity. You can do this by making it have the maximum operation voltage range possible in the 5V power
voltage.
