Local bus clock to output high impedance for LAD/LDP
Notes:
1. The symbols used for timing specifications follow the pattern of t
2. All timings are in reference to LSYNC_IN for PLL enabled and internal local bus clock for PLL bypass mode.
3. All signals are measured from BV
4. Input timings are measured at the pin.
5. For purposes of active/float timing measurements, the Hi-Z or off state is defined to be when the total current delivered
