Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

Six sixth-order Butterworth lters pro- Transparent input clamping vide improved image quality compared to typical passive Single video load drive (2V , 150 , A = 6dB) pp V solutions. The combination of low-power Standard-De ni- AC- or DC-coupled inputs tion (SD) and High-De nition (HD) lters greatly simplify DVD video output circuitry. Three channels offer xed SD AC- or DC-coupled outputs lters, while the other three are select able between SD DC-coupled outputs eliminate AC-coupling capacitors and HD lters. Low power The FMS6346 offers a xed gain of 6dB. The FMS6346 5V only may be directly driven by a DC-coupled DAC out put or an Robust (12kV HBM) output ESD protection AC-coupled signal. Internal diode clamps and bias Lead-free package - TSSOP-20 cir cuitry may be used if AC-coupled inputs are required (see Applications section for details). Applications The outputs can drive AC- or DC-coupled single (150 ) Cable and satellite set-top boxes video loads. DC-coupling the outputs removes the need for output coupling capacitors. The input DC levels are DVD players offset approxi mately +280mV at the output.
