R820T2 Datasheet – Digital TV Silicon Tuner IC

In heritage from Rafael Micro’s state-of-the-art architecture, the R820T digital silicon tuner achieves the lowest power consumption and the smallest font factor. R820T offers unmatchable RF performance for all digital broadcast television standards including DVB-T, ATSC, DMB-T, ISDB-T,. With innovative AccuTuneTM and TrueRFTM mechanisms, R820T provides superior performance in sensitivity, linearity, adjacent channel immunity, and image rejection. The chip embeds a smart power detector to optimize different input power scenarios as well as the spurious free dynamic range.

The R820T is a highly integrated silicon tuner that builds in low noise amplifier (LNA), mixer, fractional PLL, VGA, voltage regulator and tracking filter, eliminating the need for external SAW filters, LNA, balun, and LDO. Thanks the LNA architecture, R820T offers the lowest cost and high performance solution for digital TV application. On-chip LDO, high performance LNA, and small package enable R820T the perfect solution for both cost and font factor sensitive applications.

With proprietary GreenRF techniques, R820T achieves both high performance and the lowest power consumption which perfectly compliant with the worldwide trend. The R820T comes in a small and thin QFN RoHs compliant package.
