Differential CLK input-straight output mode

• CLKEP = CLKEN = 140 MHz (max)

• CLKA = CLKB = “L” (DVSS)

• CKSEL = “H” (AVDD)

• DSEL = “H” (DVDD)

• RESET = “H” (DVDD)

• CE = “L” (AVSS)

• OE = “L” (DVSS)

• Differential CLK input — Solid line: CLKEP, Dotted line: CLKEN

• VINA input — Sampling at CLKEP rising (CLKEN falling)

• DA0 to DA7 — Output (after 5 CLK + tpdS from Sampling) at CLKEP rising (CLKEN falling)
