Datasheet

The LMH0024 correctly handles equalizer pathological sig-
nals for standard definition serial digital video, as described
in SMPTE RP 178.
OUTPUT INTERFACING
The SDO and SDO outputs are internally loaded with 50Ω.
They produce a 750 mV
P-P
differential output, or a
375 mV
P-P
single-ended output.
Application Information
PCB LAYOUT RECOMMENDATIONS
Please refer to the following Application Note for the CLC034
on National's website: AN-1372, “LMH0034 PCB Layout
Techniques.” The PCB layout techniques in this application
note apply to the LMH0024 as well.
REPLACING THE GENNUM GS9064
The LMH0024 is footprint compatible with the Gennum
GS9064. Pin 16 (MUTE) of the LMH0024 must be connect to
ground for correct operation.
SUPPLY CURRENT VS. CABLE LENGTH
The supply current (I
CC
) depends on the amount of cable be-
ing equalized. The current is highest for short cable and
decreases as the cable length is increased. Figure 2 shows
supply current vs. Belden 1694A cable length for 270 Mbps
data.
