Si2151 Worldwide Digital and Analog TV Tuner Description Features - Worldwide hybrid TV tuner - NTSC, PAL/SECAM, ATSC/QAM, DVB-T2/T/C2/C, The Si2151 is the industry's most advanced hybrid TV tuner supporting all worldwide terrestrial and cable TV standards for digital and analog TV reception. Leveraging five generations of field-proven hybrid TV tuner technology, the Si2151 delivers the same or better RF performance as Silicon Labs' Si2157 hybrid TV tuner while further reducing footprint size and bill of materials cost. Available in an industry-leading 3x3 mm QFN package, the Si2151 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 Si2151 provides several dB of improved reception performance compared to competing solutions. Additionally, a software-selectable cable mode offers optimized return loss. The Si2151 delivers exceptional picture quality and a higher number of received stations when compared to other silicon tuners. Incorporating worldwide field experience from five prior hybrid tuner generations in mass production, the Si2151 delivers the highest tolerance to real-world reception conditions. nel bandwidths - Industry-leading margin to A/74, NorDig, D-Book, C-Book, ARIB, EN55020, OpenCable™, DTMB - Lowest BOM for a silicon hybrid 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 - Applications ANTENNA INPUT PGA 0 / 90 LDO FREQ SYNTH Hybrid ½-NIM tuner module iDTV (Integrated Digital TV) Hybrid terrestrial and cable STB Hybrid PVR, DVD and Blu-Ray disc recorder PC-TV accessories AGC I ADC DSP Q ADC FILTER IF AGC LOW-IF 3.3 V 1.8 V 1.8 V XOSC Copyright © 2014 by Silicon Laboratories LIF AGC DTV DEMOD ATV DEMOD SDA SCL ADDR AV SoC GPIO XOUT XTAL_I XTAL_O Hybrid TV Tuner OUTPUT INTERFACE - PGA RF AGC operation Integrated power-on reset circuit Single LIF output to SoC and/or demodulator Standard CMOS process technology Smallest footprint for a silicon hybrid TV tuner - 3x3 mm, RoHS-compliant 24-pin QFN CONTROL INTERFACE Si2151 ISDB-T/C, DTMB - 1.7 MHz, 6 MHz, 7 MHz, 8 MHz, and 10 MHz chan- 9.29.2014 Si2151 Worldwide Digital and Analog 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 506 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, ATV Mode 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) Analog IF Spurious Distortion S=P –72 dB 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 Si2151 EVB.
