RSKM RxIN Skew Margin (2) (Figure 15) f = 25 MHz 750 ps
f = 65 MHz 500 ps
(1) Typical values are given for VCC = 3.3V and TA= +25C.
(2) Receiver Skew Margin is defined as the valid data sampling region at the receiver inputs. This margin takes into account the
DS90C383B transmitter pulse positions (min and max) and the receiver input setup and hold time (internal data sampling window -
RSPos). The RSKM will change when different transmitters are used. This margin allows for LVDS interconnect skew, inter-symbol
interference (both dependent on type/length of cable), and clock jitter (less than 250 ps).
