Replacing AD9633 with GX9633 Quad-Channel 12-Bit 125MSPS ADC in High-Speed Industrial Cameras

High-speed industrial cameras are typically installed on machine assembly lines to replace human eyes for measurement and judgment. They capture targets through digital imaging and convert them into image signals, which are then transmitted to a dedicated image processing system. The image processing system performs various computations on these signals to extract target features, and then controls on-site equipment actions based on the discrimination results. With their ability to capture extremely fast motion and transient events, high-speed industrial cameras are widely used in many fields.

The data acquisition rate and resolution of high-speed industrial cameras are far higher than those of ordinary industrial cameras. The GX9633 quad-channel 12-bit 125MSPS analog-to-digital converter (replacing the AD9633) is positioned to precisely meet the operational requirements of high-speed industrial cameras. With low power consumption of only 100mW per channel (at 125MSPS) and a 650MHz full-power analog bandwidth, it is a suitable choice for high-speed industrial cameras that require both multi-line-scan signal acquisition and a compact design.

The GX9633 features an on-chip sample-and-hold circuit, enabling low cost, low power, small size, and ease of use for the system. The product operates at conversion rates up to 125MSPS and is optimized for applications where small package size is critical, achieving excellent dynamic performance and low power consumption. The GX9633 requires a single 1.8V power supply and an LVPECL/CMOS/LVDS-compatible sampling rate clock for full-performance operation. In many applications, no external reference or driver components are required.

GX9633 Product Features:

• Pin-to-pin replacement for AD9633

• 1.8V power supply operation

• Low power: 100mW per channel at 125MSPS, with scalable power options

• SNR = 71dB

• SFDR = 91dBc

• DNL = +0.3LSB (typical); INL = +0.5LSB (typical)

• Serial LVDS (ANSI-644 by default) and low-power, reduced-signal options

• 650MHz full-power analog bandwidth

Q1: What are the alternative models for AD9633?

A: Yes. GXSC GX9633 is an ADC solution for replacing the ADI AD9633. It is recommended to contact the GXSC team directly to confirm replacement details and specifications.

Q2: Is GX9633 pin-compatible with AD9633? Does the PCB need to be modified during replacement?

A: The GX9633 is positioned as a replacement solution for the AD9633. This means it is designed for direct replacement in terms of package and pin definitions, with the goal of completing the chip replacement without modifying the existing PCB layout. However, before mass production, it is recommended to request the GX9633 package drawing and pin definitions from GXSC.

Q3: After replacing AD9633 with GX9633, can the existing drivers and firmware continue to be used?

A: The GXSC official website describes the GX9633 as a "hardware and software replacement" solution. The ADC supports serial port control and features programmable output clock and data alignment. During the sample verification stage, GXSC provides software development and product debugging support to assist with this step.

Q4: Is the procurement cost of GX9633 lower than that of AD9633?

A: As a GXSC chip solution, the GX9633 has structural advantages in supply chain cost and delivery lead-time controllability. The specific procurement cost depends on project volume, package type, and cooperation model. It is recommended to contact the GXSC sales team at [email protected], providing the estimated annual usage and target price to obtain a quotation. GXSC is positioned as a domestic chip agent and solution service provider, and volume projects typically have room for negotiation.

Q5: Does GX9633 support sample requests? How can I get in contact?

A: Yes. According to the GXSC official website and public promotional information, customers can apply for samples and technical support through the following channels.
