• Differential CLK input — Solid line: CLKEP, Dotted line: CLKEN
• VINA input — Sampling at CLKEP rising (CLKEN falling)
• DA0 to DA7 — Output (after 5 CLK + tpdM2 from Sampling) at CLKEP rising (CLKEN falling)
• DB0 to DB7 — Output (after 5 CLK + tpdM2 from Sampling) at CLKEP rising (CLKEN falling)
