7.4 TIMING GENERATION (TG MODULE)
The Timing Generation (TG) sub-module generates all the timing information signals required for ITU-R BT.470
compliant TV signals. An internal pixel counter generates horizontal and vertical timing signals and an internal
Discrete Time Oscillator (DTO) makes the phase signals of sub-carrier.
There are two kinds of horizontal and vertical timings in TG module, namely:
7.4.1 525/60 HZ
Video standard: NTSC (M), NTSC-J, PAL (M), NTSC 4.43, and PAL 60
Horizontal frequency (FH): 15.734 kHz, 858 samples per line @ 13.5 MHz sample rate
Vertical frequency (FV): 59.94 Hz, 525 lines per frame
7.4.2 625/50 HZ
Video standard: PAL (BGHID), PAL (N), and PAL (Nc)
Horizontal frequency (FH): 15.625 kHz, 864 samples per line @ 13.5 MHz sample rate
Vertical frequency (FV): 50.00 Hz, 625 lines per frame
There are four kinds of discrete timing oscillation for sub-carrier generation in TG module, namely:
7.4.3 3.579545 MHZ
Video standard: NTSC (M) and NTSC-J
Sub-carrier frequency (FSC): 910/4 * FH
7.4.4 4.43361875 MHZ
Video standard: PAL (BGHID), PAL (N), NTSC 4.43, and PAL 60
Sub-carrier frequency (FSC): (1135/4 + 1/625) * FH
7.4.5 3.57561149 MHZ
Video standard: PAL (M)
Sub-carrier frequency (FSC): 909/4 * FH
7.4.6 3.58205625 MHZ
Video standard: PAL (Nc)
Sub-carrier frequency (FSC): (917/4 + 1/625) *
