Product Details
AD9267BCPZ - Dual Continuous-Time Sigma-Delta Modulator
AD9267BCPZ is the Analog Devices tray-order code for a dual continuous-time sigma-delta modulator with 10 MHz real or 20 MHz complex signal bandwidth. It uses a 64-lead, 9 mm by 9 mm LFCSP with an exposed pad.
Confirm the exact ordering code, lot marking and 64-lead package drawing before installation.
Overview
Each AD9267 channel combines a resistive analog input with a fifth-order continuous-time sigma-delta loop filter. The device uses 32-times oversampling and provides four-bit differential LVDS modulator data per channel at 640 MSPS. A differential data clock output assists the receiving logic in capturing data.
Key Advantages
Two simultaneous channels
Dual paths support real-bandwidth or complex I/Q receiver applications.
Wide signal bandwidth
The architecture covers 10 MHz real or 20 MHz complex bandwidth under stated conditions.
Integrated clocking
A differential clock input or on-chip integer-N PLL can provide the internal conversion clock.
Input filtering
The continuous-time loop filter attenuates out-of-band signals and aliases.
Feature Summary
Serial configuration
The SPI-compatible port controls operating features and register settings.
LVDS output
Each channel presents a four-bit differential LVDS data bus and overrange indication.
Data clock
DCO differential outputs provide a timing reference for downstream capture logic.
Low-voltage operation
The documented analog supply is 1.8 V; verify all supply and driver rails against the data sheet.
Package & Footprint
ADI specifies a 64-lead LFCSP, 9 mm by 9 mm, with an exposed paddle. The catalog case name is 64-VFQFN Exposed Pad, CSP. The local register contains only a broader 64-VFQFN Exposed Pad name, so the exact CSP-suffixed mapping requires review.
- Use the ADI 64-lead package outline and pin-one marker.
- Solder the exposed paddle to analog ground as directed by the data sheet.
- Verify the pad geometry, thermal path and solder-mask design for the supplied lot.
The exact registered JPG is missing. Do not approve the package illustration until it is verified.
Pin Functions
The ADI Rev. 0 data sheet provides the numbered 64-lead pin configuration and function table. These groups summarize functions, not a substitute for that pin table.
Analog inputs
VIN+A/VIN−A and VIN+B/VIN−B are the differential channel inputs; VREF and CFILT support reference and filtering.
Clock and PLL
CLK+/CLK− accept a differential clock; PLLMULT pins select multiplication and PLL_LOCKED indicates lock.
Data and status
D0± through D3± for each channel carry LVDS data. DCO± and OR± provide clock and overrange signals.
Control and supplies
CSB, SCLK, SDIO, RESET and PDWN pins govern configuration; AVDD, DVDD, DRVDD and CVDD have separate roles.
Pins marked DNC must not be connected; exposed pad pin 65 must be soldered to the analog-ground plane.

Replacement Considerations
AD9267BCPZRL7 is an ADI ordering option for reel packaging of the same device family, but purchasing format alone does not establish full lot or board equivalence. Any proposed electrical substitute must be checked for continuous-time architecture, bandwidth, clocking, LVDS data format, SPI setup, supply rails and the exact 64-lead footprint. No unverified internal alternative link is shown.
Manufacturer Information
Analog Devices publishes the AD9267 product page, Rev. 0 data sheet and package resources. The exact BC PZ tray code appears in ADI's ordering table. The page lists the order code in production while the family heading says not recommended for new designs; procurement should confirm current orderability and lead time.
Applications
Wireless receivers
Baseband quadrature reception in the communication systems identified by ADI.
Instrumentation
Quadrature sampling instruments requiring wide bandwidth and dynamic range.
Existing designs
Maintenance of qualified receiver boards using this exact device and footprint.
Signal-chain evaluation
Bench evaluation of continuous-time sigma-delta conversion and LVDS capture.
Quality & Authenticity
Check the full marking, tray labeling, date and lot code, package dimensions, moisture handling and traceability before assembly. Verify the source and test evidence for any independent-distributor lot. This listing does not imply a current authorized-stock quote or a completed incoming inspection.
FAQ
How many signal paths are integrated?
Two continuous-time sigma-delta modulator channels.
What is the output format?
Four-bit differential LVDS data per channel at the modulator rate, plus a differential data clock.
Is it recommended for a new design?
ADI marks the family not recommended for new designs despite listing this order code in production.
Is the package artwork verified?
No. The exact case-name registration and JPG remain pending review.
Engineering Notice
Keep this detail under review until the exact package registry entry and JPG, ADI lifecycle/orderability, supplied-lot identity and a current qualified stock/price quote are confirmed. Do not publish while any gate remains open.
