Samsung Proposes Very Low Power 12Gbps CIS Interface

MDPI Sensors publishes "A 12-Gb/s Stacked Dual-Channel Interface for CMOS Image Sensor Systems" paper by Sang-Hoon Kim, Hoon Shin, Youngkyun Jeong, June-Hee Lee, Jaehyuk Choi, and Jung-Hoon Chun from Sungkyunkwan University and Samsung, Korea.

"We propose a dual-channel interface architecture that allocates high and low transition-density bit streams to two separate channels. The transmitter utilizes the stacked drivers with charge-recycling to reduce the power consumption. The direct current (DC)-coupled receiver front-end circuits manage the common-mode level variations and compensate for the channel loss. The tracked oversampling clock and data recovery (CDR), which realizes fast lock acquisition below 1 baud period and low logic latency, is shared by the two channels. Fabricated in a 65-nm low-power complementary metal-oxide semiconductor (CMOS) technology, the dual-channel transceiver achieves 12-Gb/s data rate while the transmitter consumes 20.43 mW from a 1.2-V power supply."

Photonics Spectra on Emerging Image Sensor Applications

Photonics Spectra publishes an article " Emerging Applications Drive Image Sensor Innovations " Hank Hogan. Few quotes: " Vendors are responding by increasing sensor spectral range, integrating new capabilities into devices, and adding features such as 3D imaging. The result can be rapid growth in sensors, even in areas that are relatively stable. For instance, the worldwide market for cars is expanding at a relatively modest pace, according to Geoff Ballew, senior director of marketing in the automotive sensing division of chipmaker ON Semiconductor Corp. of Phoenix. However, tepid growth is not the case for the automotive imaging solutions. “The number of sensors consumed and attached to those cars is growing wildly,” he said. “The image sensor chip business is growing in excess of 15 to 20 percent a year. The reason for that is cameras increasingly are adding new functionality to cars.” Automotive sensors are expected to work from -40 to 125 °C. That interacts with th

ON Semi Unveils its First SiPM for LiDARs

ON Semi publishes its first sensor for LiDARs , possibly coming from SensL acquisition: " The RA−Series 16−pixel linear array from ON Semiconductor has been designed for automotive LiDAR applications. The array is a single monolithic sensor featuring 16 of ON Semicondcutor’s industry−leading silicon photomultiplier (SiPM) pixels. The SiPM is a single−photon sensitive, high internal gain sensor that has a responsivity of >30 kA/W at 905 nm and operates at a low bias of less than 50 V. "

Cepton to Integrate its LiDAR into Koito Headlights

BusinessWire : Cepton, a developer 3D LiDAR based on stereo scanner, announces it will provide Koito with its miniaturized LiDAR solution for autonomous driving. The compact design of Cepton’s LiDAR sensors enables direct integration into a vehicle’s lighting system. Its Micro-Motion Technology (MMT) platform is said to be free of mechanical rotation and frictional wear, producing high-resolution imaging of a vehicle’s surroundings to detect objects at a distance of up to 300 meters away. “ We are excited to bring advanced LiDAR technology to vehicles to improve safety and reliability, ” said Jun Pei, CEO and co-founder of Cepton. “ With the verification of our LiDAR technology, we hope to advance the goals of Koito, a global leader within the automotive lighting industry producing over 20 percent of headlights globally and 60 percent of Japanese OEM vehicles. ” Before Cepton, Koito used to cooperate with Quanergy with the similar claims a year ago . Cepton technology is based on mecha
