Local bus clock to data valid for LAD/LDP
Local bus clock to address valid for LAD, and LALE
Output hold from local bus clock (except LAD/LDP and
LALE)
Output hold from local bus clock for LAD/LDP
Local bus clock to output high Impedance (except
LAD/LDP and LALE)
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 local bus clock for PLL bypass mode. Timings may be negative with respect to the local bus
3. Maximum possible clock skew between a clock LCLK[m] and a relative clock LCLK[n]. Skew measured between
