First wafer level sensor chip available

On January 17, Ams AG, a leading provider of high-performance sensor solutions and analog ICs, announced the world's first cost-effective multi-channel, on-chip, sensor-on-a-chip solution for a new generation of consumer and industrial applications The spectrum analyzer opens the way.

In a small 4.5 x 4.4 mm array package, the ultra-low power AS7262 visible light sensor and the AS7263 near-infrared sensor provide six calibrated spectral channels. The competitive price advantage makes this new multi-channel spectral sensor open the door for testing and use of consumer products as well as various applications in the real world. Its main solutions include material and product certification, product quality and integrity, and material content analysis in the near infrared (NIR) and visible spectrum.

Jean Francois Durix, Marketing Director of Emerson Semiconductor's Emerging Sensor Systems, said: “The increasing integration of sensors into smartphones and tablets has created a new wave of mobile applications. The introduction of AS7262 and AS7263 enable broad-scale spectral analysis The application brings a revolutionary development to spectral sensing innovation in industrial and consumer applications.The new spectral sensing solution greatly reduces the cost and size of spectrum analysis, and is widely used in food safety, product certification, routine testing, etc. Application to help better protect people's health and living environment."

Multispectral sensors use new manufacturing techniques that enable nano-optical interference filters to attach directly to CMOS silicon wafers with extreme precision. The interference filter technology used in this sensor has extremely high accuracy and stability, is not affected by the use time and temperature, and is smaller and more cost-effective than the components commonly used today in various types of optical spectrum analysis instruments.

The integrated smart AS7262 six-channel visible light sensor provides calibrated digital output through an I2C or UART interface. It measures the light intensity of six different wavelengths in the visible range: 450 nm, 500 nm, 550 nm, 570 nm, 600 nm, and 650 nm. AS7263 can detect the near-infrared spectra of 610nm, 680nm, 730nm, 760nm, 810nm and 860nm infrared characteristics. Both products contain an electronic shutter with LED driver circuitry, which means that the device designer can accurately control the light source and spectral detection functions from a single chip.

The new multi-spectral sensors are characterized by their small size and low power consumption, and measurement equipment OEMs can use these features to easily develop new products. For example, cumbersome lab-level analysis equipment can now be replaced by handy handheld devices. At the factory, samples produced today have to be sent from the production line to the laboratory for chemical analysis, and future quality inspections can be done on the production line with a new compact, robust spectrometer based on multispectral sensors.

POE ONU

In general, ONU devices can be classified according to multiple application scenarios such as SFU, HGU, SBU, MDU, and MTU.
1. SFU type ONU deployment
The advantage of this deployment method is that the network resources are relatively abundant, and it is suitable for independent households in the FTTH scenario. It can ensure that the user terminal has broadband access functions, but does not involve more complicated home gateway functions. The SFU in this environment has two common forms: it provides both an Ethernet interface and a POTS interface; it only provides an Ethernet interface. It should be noted that SFU can provide coaxial cable functions in both forms to facilitate the realization of CATV services, and it can also be used with home gateways to facilitate the provision of value-added service functions. This scenario is also applicable to enterprises that do not need to exchange TDM data.
2. HGU type ONU deployment
The HGU type ONU terminal deployment strategy is similar to the SFU type, except that the functions of the ONU and RG are integrated in hardware. Compared with SFU, it can realize more complicated control and management functions. The U-shaped interface in this deployment scenario is built into the physical device and does not provide an interface. If you need to provide an xDSLRG device, you can directly connect multiple types of interfaces to the home network, which is equivalent to a home gateway with an EPON upstream interface. Used in FTTH occasions.
3. SBU type ONU deployment
This deployment scheme is more suitable for independent enterprise users to construct the network under the FTTO application mode, and is based on the enterprise change of SFU and HGU deployment scenarios. The network in this deployment environment can support broadband access terminal functions and provide users with multiple data interfaces including El interface, Ethernet interface, and POTS interface, which can meet the needs of enterprises in data communication, voice communication, and TDM dedicated line services. Usage requirements. The u-type interface in the environment can provide enterprises with a frame structure with multiple attributes, which is more powerful.
4. MDU type ONU deployment
This deployment scheme is suitable for multi-user network construction under multi-application modes such as FTTC, FTTN, FTTCab, and FTTZ. If enterprise-level users have no demand for TDM services, this solution can also be used for EPON network deployment. This deployment solution can provide broadband data communication services for multiple users, including Ethernet/IP services, VoIP services, and CATV services and other multi-service modes, with powerful data transmission capabilities. Each of its communication ports can correspond to a network user, so in comparison, its network utilization rate is higher.
5. MTU-type ONU deployment
The deployment plan is based on the commercialization of the MDU deployment plan. It can provide multi-enterprise users with multiple interface services including Ethernet interfaces and POTS interfaces, and can meet enterprise voice, data, TDM private line services and other services demand. If combined with the slot type implementation structure, richer and more powerful business functions can be realized.
