Table 4. PLL Value Calculation
en_vsync
PLL frequency [MHz]
PLL[12:0]
0
5, 10, 20, 40
not used
5
5 MHz / (26 x fVSYNC)
10
10 MHz / (50 x fVSYNC)
1
20
20 MHz / (98 x fVSYNC)
40
40 MHz / (196 x fVSYNC)
PLL frequency is set by PWM_RESOLUTION[1:0] bits.
For Example:
If fPLL = 5 MHz and fVSYNC = 60 Hz, then PLL[12:0] = 5000000 Hz / (26 * 60 Hz) = 3205d = C85h.
If fPLL = 10 MHz and fVSYNC = 75 Hz, then PLL[12:0] = 10000000 Hz / (50 * 75 Hz) = 2667d = A6Bh.
