Analog Devices Inc. AD9942BBCZ

Each channel supports CCD signal conditioning at pixel rates up to 40 MHz. The device combines correlated double sampling, variable gain, optical-black clamping and 14-bit conversion with clock and reset-gate timing drivers. It was designed for dual-output imaging architectures, not as a standalone image sensor.

• Two matched imaging channels in one device.
• 14-bit conversion at up to 40 MSPS per channel.
• Integrated CCD clock and reset-gate drivers.
• Fine programmable timing adjustment below 550 ps resolution.
• Compact 9 x 9 mm 100-ball package.

Each analog front end includes a correlated double sampler, 0 to 18 dB 9-bit VGA, optical-black clamp and ADC. The timing core drives RG_A/RG_B and H1A to H4A/H1B to H4B clock sets, including a four-phase H-clock mode. A six-wire serial interface programs both channels.

Analog Devices lists the exact AD9942BBCZ order code in a 100-ball CSP_BGA, 9 x 9 x 1.4 mm. The catalog describes a 100-LFBGA/CSPBGA. The local package register has a generic 100-LFBGA entry but does not by itself establish the 9 x 9 mm ball map; check the manufacturer's controlled footprint. Its registered JPG is absent.

Assembly checks

• Confirm 9 x 9 mm body and ball grid.
• Use the official ball map for routing.
• Validate moisture handling and reflow profile.

Channel A uses CCDIN_A at A1, serial controls SL_A at B2, SDATA_A at C2 and SCK_A at D2, and reference balls REFT_A at C1 and REFB_A at D1. Channel B has corresponding CCDIN_B, serial and reference connections. H1 through H4 and RG outputs drive the CCD timing path. Follow the manufacturer's full 100-ball assignment for supplies, grounds, drivers and no-connects.

Check the full manufacturer timing and electrical tables for limits and loading.

Analog Devices' discontinuance notice names ADDI7013BBCZ as a replacement candidate but explicitly says it is not pin-to-pin compatible. No database-verified drop-in alternative is linked. Redesign and verify timing, register configuration, clock drivers, power domains and the ball map before substitution.

Analog Devices publishes the AD9942 Rev. A data sheet and lists AD9942BBCZ as obsolete. Its product discontinuance notice identifies the non-pin-compatible replacement candidate. Use current manufacturer documents and equipment-specific requirements for repair decisions.

• Dual-channel CCD imaging systems.
• Legacy digital still and video cameras.
• High-speed imaging equipment designed for the AD9942 ball map.

For this obsolete device, verify full markings, lot traceability, storage history, solder-ball condition and package dimensions. Public broker inventory is not a confirmed authorized live quotation. The catalog price and quantity remain unverified and must not be represented as current distributor terms.

Validate the CCD input network, clamp levels, ADC timing, serial control, supply sequencing and every ball assignment before board use. Missing package JPG, unresolved registry footprint details and unverified live authorized inventory and tier prices prohibit publication.
