In high-end fields such as RF communication, testing and measurement, and defense electronics, ultra-high-speed analog-to-digital converters (ADCs) serve as the core link in signal chains, where their sampling rate, linearity, and compatibility directly determine the system's performance limits. The current high-speed ADC industry faces three major challenges: imported ultra-high-speed ADC products are exposed to risks of supply chain instability and high costs; most products struggle to balance ultra-high-speed sampling with low power consumption; and as the demand for complex systems increases, higher requirements are placed on device adaptability and calibration convenience.

Corebai Microelectronics' CBM08AD1500QP, an 8-bit dual-channel ultra-high-speed ADC built on CMOS technology, seamlessly replaces the imported benchmark ADC08D1500 as the preferred domestic solution to address industry pain points.

The CBM08AD1500QP is developed through precision-engineered design for industrial applications and technological innovation, with all performance metrics fully implemented in engineering practice.

Ultra-high-speed sampling with flexible scalability: Each channel delivers a standard sampling rate of 1.5 GSPS, which can be boosted to 3.0GSPS via time-division dual-edge sampling (DES) mode. The clock frequency spans 200MHz to 1500MHz, enabling stable capture of high-frequency signals below 500MHz to meet demanding requirements like RF direct sampling and transient waveform capture. It supports SDR/DDR dual-output modes and LVDS differential output (adjustable to 400~1000mVpp), compatible with various backend data reception links.

Precision and power efficiency: With 8-bit resolution, the differential nonlinear error (DNL) is only ±0.4LSB, and the integral nonlinear error (INL) typically reaches ±0.6LSB, ensuring quantization accuracy without missing codes. The signal-to-noise ratio (SNR) typically reaches 45dB, with an effective number of bits (ENOB) of 7.2 and a signal-to-noise distortion ratio (SINAD) of 44.5dB, outperforming similar products in dynamic performance. Powered by a single 1.9V±0.1V supply, the typical power consumption is only 2.0W, with analog power current at 900mA and digital power current at 220mA, significantly reducing system power load in ultra-high-speed sampling scenarios.

In intelligent calibration and flexible control: The product features built-in automatic correction functions for gain, offset, and inter-channel clock synchronization, supporting both power-on auto-calibration and command-triggered correction. During drastic temperature changes, restarting the calibration process restores optimal performance, significantly reducing system debugging complexity. The product offers dual control modes: Standard mode allows quick configuration of full-scale range, output amplitude, and other parameters via pins; Extended mode accesses 9 registers through a 3-wire serial interface, enabling 512-step full-scale adjustment and 512-step offset adjustment to meet the precision requirements of complex systems.

Seamless Compatibility and High Reliability: The TI ADC08D1500 features a pin layout and functional performance fully compatible with existing systems, enabling direct replacement without PCB modifications to significantly reduce the R&D cycle for domestic alternatives. Encapsulated in TQFP128, it operates within an industrial-grade temperature range (-45℃ to 85℃), provides ESD protection up to 2000V (human body model), meets MSL3 humidity sensitivity standards, and complies with RoHS regulations, ensuring long-term stable operation in harsh environments.

application scenarios

In digital oscilloscope applications, the 3.0GSPS sampling rate enables capture of nanosecond-level transient signals. Its LVDS high-speed output with low linearity error ensures waveform reconstruction accuracy, making it compatible with high-speed channel designs in mid-range oscilloscopes.

For communication receivers and RF down-conversion, the differential analog input supports a wide-range adjustment of 570~1100mVpp, meeting the requirements for balanced RF signal transmission. With a 1.5GSPS sampling rate, it can handle 5G NR intermediate frequency signal processing.

In the high-speed digital acquisition, the product supports multi-device synchronization, and the clock synchronization is achieved by setting pulse, which can satisfy the requirement of time consistency of multi-channel high-speed data acquisition system.

In radar and electronic countermeasures applications, the system features a wide temperature range, low-power design, and interference-resistant LVDS output, meeting the reliability and collaborative requirements of defense electronics. Its clock duty cycle correction ensures sampling stability in complex electromagnetic environments.

The CBM08AD1500QP stands out with its core strengths: uncompromising ultra-high-speed sampling, barrier-free domestic substitution, and high reliability for engineering applications. Through precise parameter design, flexible control modes, and seamless compatibility, it effectively addresses the industry's dual concerns about performance and supply chain in ultra-high-speed ADCs. Against the backdrop of accelerated domestic substitution, this product not only provides a cost-effective solution for system upgrades but also injects new momentum into the autonomous development of high-end electronic equipment, as demonstrated by the widespread adoption of domestically produced high-end PET/CT devices in the medical field.
