ADC GX08200 Replaces ADC08200 for LIDAR

LIDAR measures the distance, speed and shape of a target by transmitting laser pulses and receiving reflected light. The received light signals are first converted into analog electrical signals, and an analog-to-digital converter quickly and accurately converts these analog electrical signals into digital signals for subsequent digital processing and analysis.

High-precision analog-to-digital converters are capable of digitizing weakly reflected light signals at fine quantization levels to capture minute signal changes, which is critical for measuring precise distance and detail information for long-distance or low-reflectivity targets. the GX08200 is a low-power, high-speed analog-to-digital converter. the chip can achieve up to 1GSPS of 8-bit data conversion for a single channel driven by the external input clock. the high sampling rate makes it possible to convert the data to digital signals quickly and accurately. bits data conversion, high sampling rate can ensure timely access to the rapidly changing reflection signal, so as to accurately capture the target‘s dynamic information.

The analog-to-digital converter GX08200 contains an internal reference voltage source, a serial SPI control interface, and a parallel LVDS/RSDS output clock and data. Through the serial SPI interface, data can be written to the ADC‘s internal registers to configure the ADC‘s operating state. Its application advantages are introduced as follows:

- Ultra-low power consumption: 510mW@1GSPS

- Signal input frequency range: 0-500MHz

- Maximum differential signal input range: 1Vpp-1.2Vpp

- PD, RSTN, SPI control interfaces support 1.8V CMOS logic.

- Parallel LVDS/RSDS output

- Operating ambient temperature: -40°C to 105°C

- 7x7mm2 QFN48 package

- Supports SPI MODE3 read and write functions
