Appendix A may be used directly. The closest frequency in Table A–1 is 169.53 MHz for which the PLL
registers are loaded with N-value register = 0xE8, M-value register = 0x1C, and P-value register = 0xB0.
The N and M numbers are the lower 6 bits of the N-value register and the M-value register respectively. The
P number is the lower two bits of the P-value register. After extracting and converting to decimal, this
becomes N = 40, M = 28, and P = 0. The resulting divide ratios for the prescalers and the post-scaler and
the resulting clock frequencies are illustrated in Figure B–4.

Figure B–4. Pixel Clock PLL Example
The equations given in subsection 2.4.1, Pixel Clock PLL give the same result for the VCO frequency and
PLL output frequency. The VCO frequency is within the specified limits.
