Si2141 Worldwide Digital TV Tuner Description Features - Worldwide digital TV tuner - ATSC/QAM, DVB-T2/T/C2/C, ISDB-T/C, DTMB - 1.7 MHz, 6 MHz, 7 MHz, 8 MHz, and 10 MHz chan- The Si2141 is the industry's most advanced digital TV tuner supporting all worldwide terrestrial and cable TV standards for digital TV reception. Leveraging five generations of field-proven digital TV tuner technology, the Si2141 delivers the same or better RF performance as Silicon Labs' Si2147 digital TV tuner while further reducing footprint size and bill of materials cost. Available in an industry-leading 3x3 mm QFN package, the Si2141 eliminates the need for an external balun, LNAs, SAW filters, and inductive power supply filtering to deliver the lowest-cost, most design-friendly and area-efficient solution available today. While competing solutions may also eliminate the balun, they suffer degradation in NF and second-order distortion, compromising reception. A fully-integrated 1.8 V LDO enables single supply operation, while a dual supply option offers additional system flexibility. Increased immunity to LTE interference and a harmonic rejection mixer with outstanding immunity to Wi-Fi interference eliminate the need for external filtering. For advanced digital broadcast standards with high-order constellations, such as DVB-T2 and DVB-C2, the superior integrated phase noise of the Si2141 provides several dB of improved reception performance compared to competing solutions. Additionally, a software-selectable cable mode offers optimized return loss. The Si2141 delivers exceptional picture quality and a higher number of received stations when compared to other silicon tuners. Incorporating worldwide field experience from five prior digital tuner generations in mass production, the Si2141 delivers the highest tolerance to real-world reception conditions. - - - Applications I ADC ANTENNA INPUT Q ADC PGA 0 / 90 LDO FREQ SYNTH Digital ½-NIM tuner module iDTV (Integrated Digital TV) Digital terrestrial and cable STB Digital PVR, DVD and Blu-Ray disc recorder PC-TV accessories IF AGC DSP FILTER LOW-IF 3.3 V 1.8 V 1.8 V XOSC Copyright © 2014 by Silicon Laboratories AGC LIF DTV DEMOD SDA SCL ADDR AV SoC GPIO XOUT XTAL_I XTAL_O Digital TV Tuner OUTPUT INTERFACE - PGA RF AGC C-Book, ARIB, EN55020, OpenCable™, DTMB Lowest BOM for a silicon digital TV tuner - No balun - No SAW filters or wire-wound inductors - Integrated LNAs and complete tracking filters Best-in-class real-world reception - Industry-leading phase noise performance - High immunity to Wi-Fi and LTE interference Low power consumption - 3.3 V and 1.8 V power supplies - Integrated 1.8 V LDO for 3.3 V single-supply operation Single LIF output to SoC and/or demodulator Standard CMOS process technology Smallest footprint for a silicon digital TV tuner - 3x3 mm, RoHS-compliant 24-pin QFN CONTROL INTERFACE Si2141 nel bandwidths - Industry-leading margin to A/74, NorDig, D-Book, 9.29.2014 Si2141 Worldwide Digital TV Tuner Selected Electrical Specifications (VDDH = 3.3 V, VDDL = 1.8 V, TA = 25 °C) Parameter Test Condition Typ Supply Voltage Total Power Consumption 1.8 and 3.3, or only 3.3 V 494 mW 42 to 1002 MHz VHF-L1 (42–103 MHz) 3.6 dB VHF-L2 (104–198 MHz) 2.3 dB VHF-H (199–470 MHz) 3.0 dB UHF (471–870 MHz) 3.2 dB Terrestrial mode 3 dB External 1.8 V supply RF Input Frequency Range NF, terrestrial* Return Loss* Unit Cable mode 8 dB VHF-H, N±18, ±36 +5 dBm VHF-H, N±1, ±2 –6 dBm 1 kHz 10 kHz 100 kHz 1 MHz –100 –100 –105 –132 dBc/Hz DSB: 125 Hz to 4 MHz offset 0.25 (–47) rms (dBc) LIF Output Center Frequency Channel BW = 6 MHz 7 MHz 8 MHz 4 to 7 4.5 to 6.5 5 to 6 MHz LIF Differential Output Voltage Programmable 0.5 to 2.0 Vppd Out-of-band IIP3* In-Band IIP3* LO Phase Noise at 860 MHz LO Integrated Phase Noise at 860 MHz *Note: Includes all connector, PCB and front-end circuit losses at the F-connector input of the Si2141 EVB.
