Product data sheet
The worst case clock skew is given by δt
The minimum allowable trace delay for the MDS signal is given by Δt = δt
In real applications, the master DAC can be anywhere and both conditions must be
satisfied: δt
Example:
⇒ 200 ps + 80 ps < Δt
⇒ 280 ps < Δt
⇒ 4.2 cm < L

clock generator skew = ± 80 ps
FR4 substrate ⇒ 15 cm/ns delay
clock trace length difference = 3 cm and 4 cm
Output sampling rate = 650 Msps
