Analog Devices Inc. AD9942BBCZRL

Each channel processes CCD output at pixel rates up to 40 MHz. Correlated double sampling, variable gain, optical-black clamping and 14-bit conversion work with a programmable CCD timing driver. The family is intended for dual-output imaging architectures, not as a standalone image sensor.

• Two imaging channels in a single IC.
• 14-bit conversion and up to 40 MSPS per channel.
• Integrated horizontal clock and reset-gate drivers.
• Sub-550 ps programmable timing resolution.
• Compact 9 x 9 mm, 100-ball package family.

The analog channels include CDS, a 0 to 18 dB 9-bit VGA, optical-black clamp and ADC. The Precision Timing core supports four-phase H-clock mode and drives RG_A/RG_B and H1A to H4A/H1B to H4B outputs. A six-wire serial interface programs the channels. Exact board timing and register settings must follow the manufacturer data sheet.

The AD9942 family data sheet describes a 100-ball, 9 x 9 x 1.4 mm CSP_BGA. The manufacturer discontinuance notice confirms the exact AD9942BBCZRL code, but the current product page displays only the BBCZ part-model row. The catalog describes 100-LFBGA/CSPBGA. The local register contains a generic 100-LFBGA entry; verify its ball map against the exact device before using it as a footprint reference.

Assembly checks

• Confirm exact ball positions and orientation.
• Verify body dimensions against the controlled drawing.
• Check storage and reflow requirements for legacy stock.

The registered JPG is missing.

For channel A, CCDIN_A is A1; SL_A, SDATA_A and SCK_A are B2, C2 and D2; REFT_A and REFB_A are C1 and D1. Channel B provides corresponding CCD input, serial and reference balls. H1 through H4 and RG outputs drive CCD timing. The full 100-ball assignment, including supplies and grounds, must be checked against the manufacturer drawing before layout or replacement.

Verify the exact order suffix, full electrical limits and packaging form with controlled manufacturer or lot records.

Analog Devices lists ADDI7013BBCZRL as a replacement candidate for AD9942BBCZRL but explicitly marks it not pin-to-pin compatible. No database-verified drop-in alternative is linked. A redesign must assess timing, serial registers, output drivers, power rails and ball map.

Analog Devices publishes the AD9942 Rev. A data sheet and the discontinuance notice naming AD9942BBCZRL. The present product-page part table displays AD9942BBCZ only, so the exact RL supply form should be reconciled with the lot and manufacturer ordering records before procurement.

• Existing dual-channel CCD cameras.
• Legacy digital still and video camera boards.
• High-speed imaging equipment already designed for this family.

Check exact markings, lot traceability, package form, storage history and ball condition. An exact-code reseller page reports zero stock, while other marketplace listings require RFQ. No current authorized-distributor USD price ladder or confirmed inventory was established; the catalog values remain unverified.

Validate CDS timing, clamp settings, register programming, supply sequencing and ball assignment. The missing JPG, unconfirmed generic package registry match, exact RL supply-form uncertainty and unverified authorized inventory/pricing prohibit publication.
