Note 1: "Absolute Maximum Ratings" are those parameter values beyond which the life and operation of the device cannot be guaranteed. The stating herein of

these maximums shall not be construed to imply that the device can or should be operated at or beyond these values. The table of "Electrical Characteristics"

specifies acceptable device operating conditions.

Note 4: Specification is guaranteed by characterization.

Note 5: Specification is guaranteed by design.

Note 6: The maximum input voltage swing assumes a nonstressing, DC-balance signal; specifically, the SMPTE-recommended color bar test signal. Pathological

or other stressing signals may not be used. This specification is for 0m cable only.

Note 7: Supply current depends on the amount of cable being equalized. The current is highest for short cable and decreases as the cable length is increased. Refer

to Figures 1, 2.

Note 8: Input return loss is dependent on board design. The LMH0034 meets this specification on the SD034 evaluation board from 5MHz to 1.5GHz.
