21ic News Silicon Labs has introduced a new generation of digital TV demodulator to support the latest satellite, terrestrial and cable standards. The new Si218x family includes the world's first demodulator to support the latest DVB-S2X specification, which provides the latest features and higher performance based on the DVB-S2 standard. The series also expands Silicon Labs' industry-leading line of terrestrial demodulator products, fully supporting the digital broadcast integrated service - the ground standard (ISDB-T) used in Latin American countries such as Brazil. The Si218x family of products meets the needs of TV and set-top box (STB) manufacturers, RF network interface module (NIM) suppliers and DVD/Blu-ray recorder manufacturers worldwide for a wide range of digital TV reception.

Silicon Labs' Si218x single-chip demodulator is based on an ever-increasing digital demodulator architecture supporting emerging and existing standards including terrestrial (DVB-T/T2, ISDB-T), satellite (DVB-S/S2) /DSS/S2X) and cable (DVB-C/C2, ITU-T J83 Annex A/B/C) reception standards. The single-channel Si218x and dual-channel Si218x2 families are market-proven, low-power, cost-effective demodulator solutions that enable TV and set-top box manufacturers to simplify complex video front-end designs and support multiple broadcast standards combination.
For terrestrial broadcast applications, Silicon Labs has the highest market share of DVB-T2 demodulator in the TV industry. Silicon Labs has incorporated its extensive field experience in the terrestrial broadcast market into the third-generation Si218x DVB-T2 demodulator and now supports the popular ISDB-T standard. Developed to achieve high quality digital video terrestrial reception, ISDB-T was first developed in Japan and is now deployed in Brazil and other 15 countries throughout South America, Central America, Africa and Asia.
Dr. Gunnar Bedicks, Principal Investigator at McKinsey Digital TV Laboratory, said: "Silicon Labs' ISDB-T demodulator and TV tuner chipset meets all ABNT NBR15604:2007Vc2008 specifications and is available in all verification projects. Significant headroom. The demodulator performs well under a variety of different receiving and testing conditions, with excellent overall performance, especially for multipath interference (direct and reflected waves) and Doppler effect.
The Digital Television Laboratory is part of the Mackenzie Presbyterian University in Sao Paulo, Brazil, and is a leader in transmission and reception systems research. Since 1997, the lab has partnered with the Brazilian Broadcasting Association (ABERT), the Television Engineering Association (SET), the Brazilian Ministry of Communications, and the Brazilian government-regulated agency ANATEL to conduct certification testing of the ISDB-T specification.
In addition to supporting the ISDB-T standard, the Si218x family also supports the latest extended standard DVB-S2X for the DVB-S2 satellite broadcast reception standard. Supports DVB-S2X demodulator, enabling developers to develop future-proof TV and set-top box designs with advanced channel recovery features and technologies, supporting the upcoming 4K Ultra HD TV based on High Efficiency Video Coding (HEVC) technology (Ultra HD TV) reception of signals. The HEVC decoding technology has been integrated into many TV SoC chips, and together with DVB-S2X reception, is becoming a "must have" feature in the TV market.
James Stansberry, senior vice president and general manager of IoT and broadcast products at Silicon Labs, said: "As a leader in the advanced digital TV demodulator market, we focus on helping global customers keep up with the pace of digital video broadcasting standards. Our new Si218x The demodulator supports the latest DVB-S2X satellite standard and the ISDB-T terrestrial standard in Latin America, enabling TV and set-top box manufacturers to develop future-proof designs and easily scale to emerging markets."
The single-channel Si218x demodulator is available in the same 7mm x 7mm QFN-48 package as Silicon Labs' previous demodulator family, providing a pin-compatible solution that simplifies board design, minimizes cost and reduces development effort. The dual-channel Si218x2 demodulator is also available in a pin-compatible 8mm x 8mm QFN-68 package with an innovative on-chip Crossbar architecture that enables system designers to meet a wide range of multi-receiver applications with cost-effective solutions. The Si218x and Si218x2 demodulators share the same API software, allowing customers to easily extend and adapt their applications to these new demodulators, upgrading their TV and STB products to support ISDB-T and the latest digital video broadcasts. standard.
In addition to the Si218x/8x2 family of products, Silicon Labs has also updated the existing Si216x/6x2 DVB demodulator family to provide new enhancements and support for the DVB-S2X standard. When paired with Silicon Labs' market-leading TV tuner, the Si216x and Si218x demodulators provide the highest performance video front-end solution from RF to baseband, helping TV manufacturers significantly simplify their designs.
