Xingong Industrial Investment completed the Angel + round of financing for Jiaoxin Technology, promoting breakthroughs in optoelectronic hybrid RF direct acquisition chip technology.

Recently, Nanjing Xingong Industrial Investment, Zijinshan Angel Fund, and Jiangning Economic Development Fund jointly completed a multi - million - yuan Angel + round of financing for Jiaoxinke (Shanghai) Intelligent Technology Co., Ltd. Multi - dimensional Capital served as the exclusive financial advisor for this round of financing.

Based on the scientific research achievements of the National Key Laboratory of Micro - Nano Engineering Science and the National Key Laboratory of Photon Transmission and Communication at Shanghai Jiao Tong University, Jiaoxinke (Shanghai) Intelligent Technology Co., Ltd. has developed a new optoelectronic hybrid ADC chip and module, which can directly sample 40GHz ultra - large bandwidth radio frequency signals, breaking through the technological blockade of the Wassenaar Arrangement on China's high - speed ADC chips.

As the application of radio signal systems migrates to high - frequency and large - bandwidth, radar, electronic reconnaissance, high - end instruments, millimeter - wave and terahertz communications pose higher requirements for the conversion rate, analog bandwidth processing capacity, quantization accuracy, and anti - interference ability of ADCs. It is already very difficult to achieve high - speed and high - precision analog - to - digital conversion of 5Gsps only relying on traditional electrical ADCs. There is an urgent need for domestic substitution of ADC/DAC technology in China.

The optoelectronic hybrid analog - to - digital conversion technology proposed by Jiaoxinke is a reliable technical solution to resolve the contradiction between the demand and performance of electronic analog - to - digital converters. By combining high - speed optical sampling at the front - end with high - precision electrical quantization processing at the back - end, it can achieve analog - to - digital conversion products with high sampling rate, large bandwidth, and high precision simultaneously. It is an effective means to overcome the limitations of traditional electronic analog - to - digital conversion technology in sampling rate, input bandwidth, clock jitter, and comparator ambiguity.

Professor Zou Weiwen, the founder of Jiaoxinke, is a National Outstanding Youth Fund winner, a National Excellent Youth Fund winner, a doctoral supervisor, a specially - appointed professor at Shanghai Jiao Tong University, and the dean of the Institute of Advanced Technology and Equipment. As the first completer, he has won the first prize of Shanghai Technological Invention Award.

Dr. Wang Xin, the CEO, is a doctor in the School of Electronic Information and Electrical Engineering at Shanghai Jiao Tong University. He led Jiaoxinke to complete the 0 - to - 1 achievement transformation and commercialization.

Dr. Li Xing, the CTO, is an associate researcher and doctoral supervisor at Shanghai Jiao Tong University. Her main research directions include ultrafast lasers, photon signal processing, and applications.

Jiaoxinke received investments from Sequoia China Seed Fund, Xiaomiao Langcheng, Jiaoda Hanyuan, and Orient Venture Capital in the angel round.

The investment from Nanjing Xingong Industrial Investment, Zijinshan Angel Fund, and Jiangning Economic Development Fund will help Jiaoxinke promote the engineering mass production of its products.

In the future, Jiaoxinke will carry out all - round cooperation with Nanjing Zijinshan Laboratory in high - speed optical communication, millimeter - wave/terahertz communication, Massive MIMO, communication - sensing integration, and high - end instrumentation.

Investors' views:

Zhang Yu, the investment director of Xingong Industrial Investment, said:

The potential of silicon - based electrical chips has been almost fully explored. Light can naturally serve as a carrier for high - frequency signals, and as a boson, it has extremely low energy consumption during propagation. With the promotion of the marginal completeness of semiconductor processes, optoelectronic integration is expected to push information technology to a new level.

In this regard, Xingong Industrial Investment has carried out a full - industrial - chain investment layout in the design, manufacturing, testing, and application of optoelectronic integration chips, aiming to build a leading - technology and highly - coordinated optoelectronic industrial cluster.
