China, Beijing, April 11, 2013. Maxim Integrated Products, Inc. (NASDAQ: MXIM) introduced the MAX2173 digital-to-audio broadcasting (DAB) RF to bitstream tuner for automotive and other mobile DAB / FM applications. As the industry's first RF-to-bitstream DAB / FM tuner, the device integrates a wireless tuner, analog-to-digital converter (ADC) and digital filter, and is directly connected to a digital signal processor (DSP) via digital I2S output. RF to bitstream design allows system designers to use existing DSPs for baseband processing. This architecture can greatly speed up the development process and implement seamless software upgrades. The integrated design saves a lot of external components in the traditional RF tuner design, effectively reducing costs, reducing BOM, and saving space. With the built-in ADC and digital filter, the MAX2173 reduces the output data rate, thereby reducing the signal processing load on the back-end DSP. The clear division of the front end and DSP in the radio design helps to simplify the system design and reduce the DSP processing load so that it can support other functions or future upgrades. The MAX2173's high-performance, high-flexibility RF front end supports DAB, FM, and terrestrial digital multimedia broadcasting (T-DMB) applications in the FM, VHF Band III, and L-band frequency bands. Main advantage · Wide range of applications: support DAB and T-DMB applications in VHF band III (168MHz to 240MHz), L band (1452MHz to 1492MHz) and FM band (76MHz to 108MHz) · SDR design has extremely high system application flexibility and supports software reuse: o Digital I2S interface can flexibly support a variety of digital baseband devices, including: DSP, application processor or dedicated baseband modem o Embedded digital filter circuit reduces the processing requirements of digital baseband · High integration: o Built-in RF tuner, ADC and digital filter reduce the processing speed, hardware cost and space of the back-end DSP o Built-in digitally controlled crystal oscillator (DCXO) eliminates the voltage controlled crystal oscillator (VCXO), effectively reducing costs and improving accuracy o Built-in low dropout voltage regulator (LDO) eliminates external regulator Industry evaluation · Vickram Vathulya, Managing Director of Maxim Integrated, said: "Maxim Integrated's latest DAB / FM tuner has revolutionized the automotive infotainment system architecture on the road to a flexible software radio solution. The DAB / FM RF The bitstream tuner provides automotive-grade RF performance, supports a very wide range of baseband products, has unmatched design flexibility, and optimizes cost, performance, and size. " Richard Robinson, Director of Strategy AnalyTIcs Automotive Industry Analysis, said: "By 2018, the semiconductor market for automotive infotainment systems will exceed $ 4 billion, and software-based functional design is becoming the main differentiator in this market."

GPON (Gigabit-Capable Passive Optical Networks) technology is the latest generation of broadband passive optical integrated access standards based on the ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. It is regarded by most operators as an ideal technology to realize broadband and comprehensive transformation of access network services. GPON was first proposed by the FSAN organization in September 2002. On this basis, ITU-T completed the formulation of ITU-T G.984.1 and G.984.2 in March 2003, and completed G.984.1 and G.984.2 in February and June 2004. 984.3 standardization. Thus finally formed the standard family of GPON. Gpon 1Ge Ont,Gpon 4Ge Ont,Gpon Ont,Gpon Onu,Vlan Shenzhen GL-COM Technology CO.,LTD. , https://www.szglcom.com

GPON technology allows operators to provide specific services that their customers need to provide in a targeted manner based on their market potential and specific regulatory environment. GPON technology and equipment are relatively complicated. GPON bears the advantages of multi-service with QoS guarantee and strong OAM capabilities to a large extent at the cost of technology and equipment complexity, which makes the cost of related equipment higher. With the development and large-scale application of GPON technology, the cost of GPON equipment will drop accordingly.
