AD9267BCPZRL7

Specialized ICS Overview

The AD9267BCPZRL7 is a dual, 4-bit, continuous-time sigma-delta modulator from Analog Devices Inc., housed in a 64-lead LFCSP-VQ (9x9 mm) package. It operates on a single 1.8 V supply and features an analog input bandwidth of 500 MHz. The device delivers 4-bit LVDS data outputs at a sampling rate of 640 MSPS in two's complement format. Key internal components include an on-chip PLL clock multiplier and a 0.5 V voltage reference.

Specialized ICS Applications

• Baseband quadrature receivers for CDMA2000, W-CDMA, multicarrier GSM/EDGE, 802.16x, and LTE
• Quadrature sampling instrumentation

Specialized ICS Procurement Notes

Verify the ordering suffix RL7 corresponds to the Tape & Reel packaging configuration as indicated in local product fields. Confirm that the specific revision matches the current Rev. C datasheet specifications. Ensure the procurement source provides valid traceability for the Analog Devices Inc. manufacturer designation. Cross-reference the 64-LFCSP-VQ package dimensions against the outline drawing in the official documentation.

Specialized ICS Selection Notes

Select this component when a low-power, high-bandwidth continuous-time sigma-delta modulator is required for direct conversion architectures. The passive input impedance simplifies front-end design by relaxing driver amplifier linearity and noise figure constraints. Consider the integrated PLL for simplified clock distribution if external jitter sources are manageable. Verify that the 4-bit output interface aligns with downstream digital signal processing capabilities for decimation and filtering.

Specialized ICS Part Context

The AD9267 belongs to the family of high-speed data converters designed for wireless communication basebands. It utilizes a continuous-time sigma-delta topology to achieve wide bandwidth without external anti-aliasing filters. The BC part number variant typically denotes specific binning or testing criteria within the standard AD9267 series, while the PZ suffix indicates lead-free RoHS compliance. The RL7 suffix specifies the reel-based packaging format for automated assembly.
