AD9208BBPZRL

Overview

The AD9208BBPZRL is a dual-channel, 14-bit analog-to-digital converter (ADC) operating at a sampling rate of 3 GSPS. It features JESD204B Subclass 1 serial digital outputs supporting lane rates up to 16 Gbps per lane. The device includes integrated input buffers with a noise density of −152 dBFS/Hz and a 9 GHz analog input full-power bandwidth. Power consumption is 1.65 W per channel at default settings. It operates on multiple DC supplies: 0.975 V, 1.9 V, and 2.5 V. Performance metrics include an SNR of 57.2 dBFS at −2 dBFS amplitude and 2.6 GHz input frequency. The component is housed in a 196-ball BGA package.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and temperature range specifications. Confirm that the procurement source provides valid traceability and authenticity guarantees for high-speed data converters. Ensure compatibility with required voltage levels and clocking schemes before finalizing acquisition.

Selection Notes

Select this component when direct RF sampling of signals up to 5 GHz is required. Evaluate the power budget carefully as total dissipation reaches 3.3 W in default modes without DDC usage. Consider the integration of digital downconverters if system complexity reduction is a priority. Verify that the receiving logic supports the necessary JESD204B lane rates and Subclass 1 synchronization requirements.

Part Context

This part belongs to the AD9208 family of high-speed ADCs from Analog Devices. It is designed for communications applications requiring wide bandwidth and low power. The device utilizes a multistage differential pipelined architecture. It is optimized for small form factor implementations while maintaining excellent linearity and high sampling rates.

Replacement Considerations

Consult official Analog Devices documentation for qualified substitute part numbers. Verify pinout compatibility and electrical parameter equivalence before substitution.
