Local Bus
Notes:
1. The symbols used for timing specifications herein follow the pattern of t
2. All timings are in reference to LSYNC_IN for DLL enabled mode.
3. All signals are measured from OV
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
6. The value of t
7. Maximum possible clock skew between a clock LCLK[m] and a relative clock LCLK[n]. Skew measured between
8. Guaranteed by characterization.
9. Guaranteed by design.
