The GXSC Analog-to-Digital Converter (ADC) replaces the ADC10D1500 for industrial/intelligent logistics LiDAR applications

LiDAR is an environmental sensing and distance measurement device. In industrial and intelligent logistics scenarios, LiDAR is widely applied, ensuring high-resolution and long-range detection, effectively enhancing operational efficiency and accuracy while reducing costs. These scenarios demand breakthroughs in LiDAR across three dimensions: cost, reliability, and adaptability,

LiDAR achieves distance and contour detection by emitting laser pulses, receiving reflected signals from targets, and calculating the time of flight (ToF). The analog-to-digital converter (ADC) within the system must feature high sampling rates, wide bandwidth, and signal fidelity. The GXSC dual-channel 10-bit 1.5GSPS high-speed ADC product is highly suitable for LiDAR applications. This chip can be pin-to-pin compatible with the ADC10D1500, offering approximately 56% lower power consumption than the comparable model and eliminating the need for a heatsink.

The GXSC analog-to-digital converter adopts a self-designed architecture, achieving excellent dynamic performance with a low power consumption of less than 2.3W. Each channel ADC features independent DDR data clocks (DCLKI and DCLKQ). When both dual-channel ADCs are operational, DCLKI and DCLKQ remain in-phase, allowing the use of either clock to sample all channels. It supports the AutoSync function for automatic synchronization, enabling multi-chip cascading. Additionally, it supports both single-board multi-ADC cascading automatic synchronization and multi-board multi-ADC cascading automatic synchronization.

The GXSC analog-to-digital converter‘s data output format can be programmed to either offset binary or two‘s complement format, allowing users to choose the preferred option. The product employs a parallel LVDS interface for data output, with a minimum conversion delay of 19ns. The data interface supports both Demux mode and Non-Demux mode. In Demux mode, two sets of 10-bit LVDS buses output data in parallel, reducing the data rate of each LVDS set by half to accommodate more data receiving devices.
