AD9267BCPZ

Specialized ICS Overview

The AD9267BCPZ is a dual continuous-time sigma-delta modulator manufactured by Analog Devices Inc. It operates at a sample rate of 640 MSPS with a 10 MHz real or 20 MHz complex analog input bandwidth. The device provides 4-bit resolution (sigma-delta modulator output) and features an SNR of 83 dB and SFDR of -88 dBc for a 10 MHz input signal. It utilizes a single 1.8 V power supply, consuming 416 mW. The component includes an on-chip PLL clock multiplier and voltage reference, offering a resistive 1 kΩ differential input impedance. Digital outputs are provided as 4-bit LVDS data in two's complement format.

Specialized ICS Feature Summary

• Dual continuous-time sigma-delta architecture with 640 MSPS sampling rate
• 10 MHz real or 20 MHz complex bandwidth with 4-bit effective resolution (modulator output)
• On-chip integer-N PLL clock multiplier and internal 0.5 V voltage reference
• Passive 1 kΩ differential input structure reducing driver amplifier requirements

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 specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range specifications. Ensure compatibility with the required 64-LFCSP-VQ (9x9) footprint during procurement planning.

Specialized ICS Selection Notes

Select this component for applications requiring high dynamic range and wide bandwidth without external antialiasing filters due to its continuous-time architecture. Consider the 4-bit LVDS output format and the necessity for downstream digital signal processing to decimate the oversampled data stream.

Specialized ICS Part Context

This part belongs to the AD9267 series of dual continuous-time sigma-delta modulators. It is designed to replace discrete solutions by integrating the modulator, clock multiplier, and reference into a single 64-lead LFCSP package, simplifying the design of wireless communication baseband receivers.
