Notes:
1. All timing (except Rise and Fall time) is referenced to the 50% level of the waveform. Input test levels are
VIH = VD – 0.4 V, VIL = 0.4 V. Rise and Fall times are referenced to the 20% and 80% levels of the waveform.
2. FSYNC/PCLK relationship must be fixed after RESET
3. The minimum RESET pulse width is the greater of 250 ns or 10 PCLK cycle times.
