Application Information
PCB LAYOUT RECOMMENDATIONS
Please refer to the following Application Note on National's
website: AN-1372, “LMH0034 PCB Layout Techniques.”
REPLACING THE GENNUM GS1524
The LMH0034 is form-fit-function compatible with the Gen-
num GS1524 and GS1524A.
SUPPLY CURRENT VS. CABLE LENGTH
The supply current (I
) depends on the amount of cable be-
CC
ing equalized. The current is highest for short cable and

decreases as the cable length is increased. Figure 1 shows
supply current vs. Belden 1694A cable length for 1.485 Gbps
