Silicon Labs Launches New TV Tuner to Further Consolidate Market Leadership

21ic News Silicon Labs today announced the launch of a new generation of silicon TV tuner products with the industry's highest performance, integration and lowest system cost to support all terrestrial and cable TV standards worldwide . Based on the enhanced features of the fifth-generation patented architecture, the new Si21x7 tuner family offers world-proven performance for TV and set-top box manufacturers, while Silicon Labs sets a record for 200 million silicon TV tuner shipments . The Si21x7 family of five products is optimized for applications such as hybrid analog/digital iDTV, analog TV, portable TV, DVD and Blu-ray recorders, and terrestrial and cable set-top boxes.

Silicon Labs' Si21x7 TV tuner family offers TV and set-top box manufacturers the best sensitivity and selectivity they expect, reduced BOM cost and low power consumption, while also enabling performance enhancements in several key areas. The Si21x7 tuner improves noise figure (NF) over the full-band range, return loss for a given NF coefficient, channel selectivity in the presence of ground blocking and full- and/or diagonal cable spectrum, and improves overall RF input Linearity over the power range. Improvements in these key areas have enhanced the reception performance of terrestrial or cable broadcasts in a variety of field conditions while extending the performance of Silicon Labs' TV tuners beyond competing solutions.

The highly integrated Si21x7 tuner is designed to deliver the lowest BOM cost silicon TV tuner solution for the mass market. Compared to competitor silicon TV tuners, the Si21x7 tuner does not require an off-chip balun at the RF input, which greatly reduces the cost and complexity of the system without performance loss. In addition, the Si21x7 TV tuner integrates all tracking filter inductors and they do not require inductive power supply filtering due to on-chip high supply ripple tolerance, which is a key consideration for board-level design. The integrated power-reset monitor and optional 3.3V single-supply power supply further reduce system cost. In addition, the Si21x7 tuner provides enhanced ESD protection and performance at the pin, which is critical for TV module design, eliminating the need for expensive ESD diodes, enabling top-of-the-line TV modules that require higher ESD immunity. Manufacturers have reduced BOM costs.

The ultra-low-power Si21x7 TV tuner operates below 500mW, which helps manufacturers minimize the power consumption of TV and set-top boxes and meet green energy standards such as Energy Star. Low-power TV tuners also simplify multi-tuner design by reducing power and thermal design requirements.

With the prevalence of indoor Wi-Fi and LTE communications, these RF signals can interfere with television reception, and it is increasingly important for television designers to consider the TV tuner's immunity to these RF signals. The Si21x7 TV tuner architecture addresses this concern by eliminating the need for off-chip filtering components to provide high Wi-Fi and LTE signal rejection. The built-in anti-Wi-Fi/LTE signal interference capability of the Si21x7 tuner makes it an ideal solution for intelligent/interconnected TVs with integrated Wi-Fi and LTE radio.

The ultra-low noise level of IF output on Silicon Labs' Si2157 and Si2127 TV tuners enables industry-leading video signal-to-noise ratio (SNR) on the analog demodulator output of audio/video SoCs, gaining more in analog broadcast reception Clear, smoother and higher quality images. Enhanced linearity over the extended RF input power range results in increased carrier composite quadratic (CSO) and composite triple beat ratio (CTB), which are the most critical parameters for wired mode reception.

Like all other Silicon Tuns TV tuners, the Si21x7 family supports global TV broadcast standards, including NTSC, PAL and SECAM for analog TVs; DVB-T2/C2/T/C, ISDB-T/C for digital TVs, ATSC/QAM and DTMB standards. To ensure maximum flexibility in mating with different system architecture TV tuners, all products within the Si21x7 family are pin compatible and share a single software API. This compatibility allows a single module or PCB design to meet the demand for digital and analog TV in a variety of TV and set-top box applications. The Si21x7 TV tuner family is also pin and API compatible with the Si21x8 family, making it possible to seamlessly connect existing customers without hardware modifications and software updates.

James Stansberry, vice president and general manager of broadcast products at Silicon Labs, said: "Since the launch of the first TV tuner in 2009, we reached a milestone of 100 million shipments in 2012. Now that one year has passed, we already have More than 200 million shipments, which shows that we maintain an exponential market momentum, no competitors can compete with us. To further consolidate the company's leading position in the video tuner market, we are the top ten TVs in the world Nine manufacturers in the manufacturer offer silicon TV tuners in batches."

As the market leader in silicon TV tuners, Silicon Labs' tuners have been adopted by almost all well-known TV manufacturers, and Silicon Labs has significant technology and performance compared to its competitors by offering the highest performance and lowest power combination. Market leading edge. The company will continue to invest in the TV tuner family to provide expanded and state-of-the-art TV tuners for new or existing customers.

Price and availability

The Si2177/57/47/37/27 TV tuner is now available in volume production and is available in a compact 4mm x 4mm 28-pin QFN package. The Si21x7 Hybrid TV Tuner series is priced at $0.85 at 10,000 units. The Si2177-A-EVB, Si2157-A-EVB, Si2147-A-EVB and Si2137-A-EVB evaluation kits are priced at $395 each, providing a complete platform for evaluating Silicon Labs TV tuners in TV and set-top box applications. .
