... CATV distribution systems Splitter modules Digital cable ready (DCR) TVs GENERAL DESCRIPTION The ADA4304-3/ADA4304-4 are 75 Ω active splitters for use in applications where a lossless signal split is required. Typical applications include multituner digital set-top boxes, cable splitter modules, multituners/digital cable ready (DCR) televisions, and home gateways where traditional solutions require discrete passive splitter modules with separate fixed gain amplifiers ...

... LFCSP (Exposed Pad) 98 Maximum Power Dissipation The maximum safe power dissipation in the ADA4304-3/ ADA4304-4 package is limited by the associated rise in junction temperature ( the die. At approximately J 150°C, which is the glass transition temperature, the plastic changes its properties. Even temporarily exceeding this ...

... A 1 μH RF choke (Coilcraft chip inductor 0805LS-102X) is required to correctly bias the internal nodes of the ADA4304-3/ ADA4304-4. It should be connected between the 5 V supply and the IL pin (Pin 14). The choke should be placed as close as possible to the ADA4304-3/ADA4304-4 to minimize parasitic capacitance on the IL pin, which is critical for achieving the specified bandwidth and flatness ...
