ZIF tuner claims lowest BOM for digital terrestrial TV
Device eliminates costly SAW filters and other external components
Claimed to offer the lowest BOM, the MAX3580 tuner uses a unique ZIF architecture and integrates an RF-tracking filter to eliminate external, discrete filtering components and the expensive SAW filter that older, IF-based tuners require. The device operates from a single 3.3-V supply and consumes 650 mW of power—suiting it for USB stick, automotive, and infotainment applications.
The integrated tuner covers an input frequency of 170 to 230 MHz for the VHF-III band and 470 to 878 MHz for the UHF band. The part also features a dynamic gain control of more than 76 dB and a typical midband noise figure of 4.7 dB referred to the LNA input. Operating temperature is 40 to 85C, and housing is in 32-pin TQFN packages. (From $5.50 ea/1,000available now.)
