AD9208BBPZ-3000

Overview

The AD9208BBPZ-3000 is a dual-channel, 14-bit analog-to-digital converter (ADC) operating at a sampling rate of 3 GSPS. It features an on-chip buffer and sample-and-hold circuit designed for low power consumption and ease of use in small form factors. The device supports direct RF sampling of wideband analog signals up to 5 GHz, with a −3 dB analog input bandwidth exceeding 9 GHz. Each channel integrates four digital downconverters (DDCs), each containing a 48-bit numerically controlled oscillator (NCO) and cascaded half-band decimation filters. The ADC utilizes JESD204B coded serial outputs supporting lane rates up to 16 Gbps per lane. Power supply requirements include nominal voltages of 0.975 V, 1.9 V, and 2.5 V.

Feature Summary

• Dual-channel architecture with integrated output error correction logic and user-selectable input ranges.
