Do the math.
There are 525 cycles at 15.734kHz.
This takes 525 / 15734 = 0.033367s = 33.367ms
This is the time it takes to generate one frame.
33.367 / 2= 16.685ms (with rounding errors) is the time to generate one field and this is the Vertical scan interval (close to 60Hz),
The fact that 525 is an odd number means that whereas the even field is in sync with the Vertical Scan, the odd field begins halfway through the Horizontal Scan.
Also, remember that you cannot stop the oscillators. You get 525 cycles at 15.734kHz but you cannot see 525 lines. Only 480 lines are visible.
