摘要：
The present invention discloses a PLL (90), which may be implemented in software, hardware, or a combination of software and hardware, which comprises a sync detector (92) adapted to output a phase error (152), a vertical sync discrete time oscillator (DTO) block (98) adapted to output a vertical sync DTO (130) based on the phase error (152), and an output logic (100) adapted to detect a vertical sync based on the vertical sync DTO (130).
