GXSC GX08D1000 Replaces ADC08D1000 for LIDAR

Solid-state LiDAR has a simple structure due to the reception of continuous light, and has the advantages of long life, high scanning accuracy, high speed, good controllability, and adaptability to temperature and vibration. In the future, it will be the main application direction in roadside unit and vehicle. A project used in the FMCW transmitter and receiver optical differential frequency signals on the ADC sampling rate requirements of the high number of data collected, the collection of dense signals.

The GX08D1000 is a dual-channel 8-bit 1.0/1.5GSPS Pipeline ADC with built-in high-performance sample-and-hold circuitry, dual-channel on-chip reference voltage source, outstanding dynamic performance and low-power characteristics, and it can acquire input signals with large bandwidth and relatively low precision.The GX08D1000 is powered by a 1.9V power supply, and the SC1282 has a high sampling rate in the input signals of The GX08D1000 is powered by a 1.9V power supply, and the SC1282 generates 7.9 RMS bits at an input signal of 103MHz at a sample rate of 1.5GSPS, while providing a BER of 10-18, and a typical power consumption of 1.98W at 1.5GSPS in non-demux mode.

Key performance of the GX08D1000 (ADC08D1000) for LiDAR applications:

Excellent accuracy and dynamic performance

Low power consumption, further reduced at lower sample rates

Internally terminated, buffered, differential analog inputs

SPI serial control interface

Dual edge sampling mode (I and Q need to provide the same input)

Output test mode

1:1 Non-demux or 1:2 Demux LVDS outputs

Automatic synchronization for multi-chip systems

Single 1.9V ± 0.1V supply

Compared with ADC08D1000, the area of GX08D1000 is 70% lower, power consumption is 50% lower, and the high and low temperature performance will be more superior. Currently, this chip has application cases in communication, radar, industrial control, instrumentation, electronic countermeasures, security monitoring and other fields.
