GPIO XOUT XTAL I XTAL O Si2141 Worldwide Digital TV Tuner Description Features The Si2141 is the industry s most advanced digital TV - Worldwide digital TV tuner tuner supporting all worldwide terrestrial and cable TV ATSC/QAM, DVB-T2/T/C2/C, ISDB-T/C, DTMB standards for digital TV reception. Leveraging five 1.7 MHz, 6 MHz, 7 MHz, 8 MHz, and 10 MHz generations of field-proven digital TV tuner technology, the channel bandwidths Si2141 delivers the same or better RF performance as - Industry-leading margin to A/74, NorDig, D-Book, C- Skyworks Si2147 digital TV tuner while further reducing Book, ARIB, EN55020, OpenCable, DTMB footprint size and bill of materials cost. - Lowest BOM for a silicon digital TV tuner Available in an industry-leading 3x3 mm QFN package, the No balun Si2141 eliminates the need for an external balun, LNAs, No SAW filters or wire-wound inductors SAW filters, and inductive power supply filtering to deliver Integrated LNAs and complete tracking filters the lowest-cost, most design-friendly and area-efficient - Best-in-class real-world reception solution available today. While competing solutions may Industry-leading phase noise performance also eliminate the balun, they suffer degradation in NF and High immunity to Wi-Fi and LTE interference second-order distortion, compromising reception. A fully- integrated 1.8 V LDO enables single supply operation, - Low power consumption 3.3 V and 1.8 V power supplies while a dual supply option offers additional system flexibility. Increased immunity to LTE interference and a Integrated 1.8 V LDO for 3.3 V single-supply harmonic rejection mixer with outstanding immunity to Wi- operation Fi interference eliminate the need for external filtering. - Single LIF output to SoC and/or demodulator For advanced digital broadcast standards with high-order - Standard CMOS process technology constellations, such as DVB-T2 and DVB-C2, the superior - Smallest footprint for a silicon digital TV tuner integrated phase noise of the Si2141 provides several dB 3x3 mm, RoHS-compliant 24-pin QFN of improved reception performance compared to Applications competing solutions. Additionally, a software-selectable - Digital -NIM tuner module cable mode offers optimized return loss. - iDTV (Integrated Digital TV) The Si2141 delivers exceptional picture quality and a - Digital terrestrial and cable STB higher number of received stations when compared to - Digital PVR, DVD and Blu-Ray disc recorder other silicon tuners. Incorporating worldwide field - PC-TV accessories experience from five prior digital tuner generations in mass production, the Si2141 delivers the highest tolerance to real-world reception conditions.
