AD9653 Replacement: GX9653 Pin-to-Pin Quad 16-Bit ADC
GX9653 is a low-power, four-channel high-speed ADC designed for AD9653 replacement and new multichannel data-acquisition systems. Each channel includes a sample-and-hold circuit and supports conversion rates up to 125 MSPS.
The device operates from a single 1.8 V supply and accepts LVPECL-, CMOS- or LVDS-compatible sampling clocks. Its high integration and small package help reduce system size and external component requirements.
GX9653 for AD9653 Replacement and New Designs
GX9653 provides a pin-to-pin migration option for existing AD9653 designs, allowing the original PCB, data interface and control architecture to be retained.
For new designs, its four synchronized ADC channels are suitable for systems requiring high channel density, 16-bit resolution and serial data transmission in a compact footprint.
Serial LVDS Output and System Compatibility
GX9653 automatically multiplies the sampling clock to generate the required serial LVDS data rate. It provides a data clock output (DCO) for data capture and a frame clock output (FCO) to identify each new output byte.
The device supports individual-channel power-down. When all four channels are disabled, total power consumption is less than 10 mW.
