12.3 HSYNC to REF Timing
12.4 CLK/2 Timing for Odd and Even Feedback Divider
For simplicity, the waveforms drawn show only the identical PECL CLK/2+ and the SSTL_3 CLK/2 signals. CLK/2-
is the compliment of the CLK/2+ signal.
Note that regardless of the CLK\2 phase at the assertion of FUNC, the clocks always have the same phase at the
fall of FUNC, regardless of 0x2
