Product Details
AD9267BCPZRL7 - Reel-Packaged Dual Sigma-Delta Modulator
AD9267BCPZRL7 is the Analog Devices reel-order code for the dual continuous-time sigma-delta modulator in a 64-lead, 9 mm by 9 mm LFCSP with exposed pad. Its 10 MHz real or 20 MHz complex bandwidth supports wideband receiver signal chains.
The RL7 suffix identifies reel ordering; confirm reel label, lot and exact package drawing before assembly.
Overview
The AD9267 integrates two continuous-time sigma-delta modulator channels with resistive analog inputs and fifth-order loop filters. A 32-times oversampling architecture provides four-bit differential LVDS data for each channel at a 640 MSPS modulator rate. Differential DCO outputs clock downstream capture circuitry.
Key Advantages
Dual-channel capture
Two channels suit I/Q baseband reception and quadrature instrumentation.
Wideband architecture
Continuous-time filtering supports 10 MHz real or 20 MHz complex signal bandwidth.
Output timing
The differential DCO signal simplifies synchronization with receiving logic.
Reel supply format
The RL7 ordering suffix is the tape-and-reel option, relevant to automated assembly procurement.
Feature Summary
Conversion loop
A fifth-order continuous-time loop filter and 32-times oversampling reduce out-of-band response.
Clock choice
A differential input clock or integrated integer-N PLL supplies conversion timing.
Configuration
An SPI-compatible serial interface configures modes and device functions.
Status outputs
Channel overrange and PLL lock indications assist system monitoring.
Package & Footprint
ADI specifies a 64-lead LFCSP, 9 mm by 9 mm, with an exposed paddle for this RL7 code. The catalog case name is 64-VFQFN Exposed Pad, CSP. The local register has only a broader 64-VFQFN Exposed Pad entry, not this exact CSP-suffixed name.
- Match the ADI 64-lead outline, exposed-pad geometry and pin-one marker.
- Solder the exposed paddle to analog ground as specified.
- Confirm reel orientation and placement setup for the supplied lot.
The exact registered JPG is absent and must be reviewed before publication.
Pin Functions
The ADI Rev. 0 data sheet has the numbered 64-lead pin table. These groups provide design context; use the original pin table for wiring.
Analog path
VIN+A/VIN−A and VIN+B/VIN−B are differential inputs; VREF and CFILT serve the reference path.
Clock and PLL
CLK+/CLK− accept differential clocking; PLLMULT pins select mode and PLL_LOCKED reports lock.
Output interface
D0± through D3± on both channels carry LVDS data; DCO± and OR± convey data timing and overrange.
Control and power
CSB, SCLK, SDIO, RESET and PDWN configure operation; AVDD, DVDD, DRVDD and CVDD supply domains require the documented layout.
Do not connect DNC leads. The exposed paddle, identified as pin 65, must be joined to analog ground.

Replacement Considerations
AD9267BCPZ is the tray-order option of this ADI family, while AD9267BCPZRL7 is the reel-order option. Packaging format does not establish lot or procurement equivalence; confirm the full marking, footprint and assembly process. A different modulator requires checks of channel count, 640 MSPS LVDS format, bandwidth, SPI configuration, clocking, supply rails and board layout. No unverified internal alternative link is included.
Manufacturer Information
ADI's product page lists AD9267BCPZRL7 as an exact order code in the 64-lead LFCSP and shows production status, while warning that the family is not recommended for new designs. The Rev. 0 data sheet supplies architecture, performance and pin functions. Distributor reel quantity and current price should be checked independently for procurement.
Applications
Wireless receiver front ends
Wideband quadrature baseband signal conversion.
Quadrature instrumentation
Two-channel sampling in high-dynamic-range test equipment.
Production assembly
Reel-format supply for an existing qualified AD9267 board.
Legacy system support
Replacement procurement for products already designed around the AD9267.
Quality & Authenticity
Verify reel labeling, full manufacturer order code, date and lot codes, moisture handling, package dimensions and traceability. Check storage and placement history for independent-distributor inventory. This detail does not claim verified live stock or an authorized current-production lot.
FAQ
What does RL7 identify?
It is ADI's reel-order option for this exact family model; confirm the supplier's reel quantity and label.
What is the output format?
Each channel outputs four-bit differential LVDS data with a differential data clock.
Is ADI recommending it for a new design?
No. ADI marks the family not recommended for new designs, despite listing this exact code in production.
Is the package JPG ready?
No. The exact case registration and local JPG are pending review.
Engineering Notice
Keep this detail under review until the exact package registry entry and JPG, supplied-lot reel labeling, orderability and a qualified current stock/price quote are confirmed. Do not publish while any gate remains open.
