Analog Devices Inc. AD9963BCPZRL

The AD9963 integrates I/Q receive and transmit conversion paths for low-power communications and instrumentation. Its receive path includes two 12-bit ADCs with a bypassable 2-times decimating low-pass filter. The transmit path includes two 12-bit DACs with programmable interpolation. Flexible full- and half-duplex digital interfaces support different system architectures.

The ADI Rev. B ordering guide specifies a 72-lead LFCSP, 10 mm by 10 mm, package option CP-72-4. The catalog calls the case 72-VFQFN Exposed Pad, CSP. The local package register has only the broader 72-VFQFN Exposed Pad entry, so this exact name and artwork require review.

Layout checks

• Compare the CP-72-4 outline and pin-one orientation with the PCB land pattern.
• Connect the exposed paddle to analog ground as required by the data sheet.
• Verify reel orientation and handling with the supplied lot.

The exact registered JPG is missing. Do not approve the illustration until it is verified.

The ADI Rev. B data sheet provides a dedicated AD9963 pin-function table. These groups summarize that table; use the numbered drawing for wiring.

The exposed thermal pad must connect to AGND; verify every supply domain and lead number in Table 9.

Use the controlled data sheet for complete limits, supply conditions and timing specifications.

AD9963BCPZ is the tray ordering option of the same AD9963 family. AD9961 is described as pin-compatible, but its 10-bit conversion differs from the AD9963's 12-bit data path, so it is not a blanket replacement. Verify bus width, filtering, supply rails, CP-72-4 footprint, software registers, package supply format and test limits. No unverified internal alternative link is included.

Analog Devices lists AD9963BCPZRL in production and recommends the AD9963 for new designs. The Rev. B data sheet contains the exact ordering guide and AD9963 pin table. Distributor listings for this reel code show differing stock and prices; current commercial availability needs direct confirmation.

Inspect full reel label, manufacturer marking, date and lot code, moisture packaging and 72-lead package geometry. Confirm traceability and incoming test requirements for any independent-distributor lot. The catalog inventory figure is not represented as a verified current distributor quantity.

Keep this detail under review until the exact package registry entry and JPG, reel lot and a qualified current distributor stock/price are confirmed. Do not publish while any gate remains open.
