The Analog-to-Digital Converter GX9653 Replaces AD9653 in Radio Receivers

In the field of wireless communication, diversity reception technology primarily addresses signal fading, interference, and obstruction. By deploying multiple receiving channels and antennas, it captures and integrates different propagation paths of the same signal, significantly enhancing the reliability and stability of communication links. This technology is widely used in mobile communication base stations, radar detection, aerospace communication, emergency rescue communication, and other applications, ensuring accurate transmission of critical commands even in complex environments. The realization of this core capability relies on a high-performance analog-to-digital converter.

The GXSC 16-bit four-channel 125 MSPS analog-to-digital converter, the GX9653, is specifically designed for multi-channel synchronous sampling scenarios. Its primary advantages focus on three key aspects: "high speed, high precision, and multi-channel coordination." It perfectly matches the diverse requirements of radio receivers for synchronous capture of multipath signals and high-precision conversion, enabling pin-to-pin replacement of Analog Devices‘ AD9653. This makes it the optimal solution for current replacements.

The GX9653 is a 4-channel, 16-bit, 125 MSPS analog-to-digital converter featuring an integrated sample-and-hold circuit. Designed specifically for low cost, low power consumption, compact size, and ease of use, the GX9653 offers a maximum conversion rate of 125 MSPS, delivering outstanding dynamic performance and low-power characteristics, making it highly suitable for applications requiring small package sizes.

The GX9653 operates with a 1.8V single power supply and supports LVPECL/CMOS/LVDS-compatible sample rate clock signals to maximize its performance. For most applications, no external reference voltage source or driver is required. To achieve the appropriate LVDS serial data rate, this analog-to-digital converter automatically multiplies the sample rate clock. It provides a data clock output (DCO) for capturing data at the output and a frame clock output (FCO) for transmitting new output byte signals. Additionally, it supports individual channel power-down modes, with power consumption below 10mW when all channels are turned off.
