AD9978BCPZ

Overview

The AD9978BCPZ is a dual-channel CCD signal processor designed for high-speed digital video applications. It integrates two complete analog front ends, each supporting pixel rates up to 65 MHz. Key internal components include black level clamping, a correlated double sampler (CDS), a sample-and-hold amplifier (SHA), and a variable gain amplifier (VGA) with 10-bit resolution covering 6 dB to 42 dB. Each channel features a 14-bit ADC operating at 65 MHz. The device utilizes a Precision Timing core providing 240 ps clock resolution and outputs data via a reduced-range LVDS interface controlled by a 3-wire serial bus.

Feature Summary

• Dual AFE channels with 14-bit, 65 MHz ADCs
• Precision Timing core with 240 ps resolution at 65 MHz
• Integrated VGA offering 6 dB to 42 dB gain range
• Configurable CDS or SHA with selectable gain steps

Applications

• Digital video cameras
• Digital still cameras
• High speed industrial cameras
• Digital copiers
• Multifunction printers

Procurement Notes

Verify the specific suffix BCPZ corresponds to the 40-lead LFCSP package and the -25°C to +85°C operating temperature range as defined in the official Analog Devices documentation. Confirm RoHS compliance status through current manufacturer declarations before procurement.

Selection Notes

Select this component when dual-channel CCD processing is required with integrated digitization. Ensure system requirements align with the 1.8 V core supply voltage and the 65 MHz maximum pixel rate. Verify that the reduced-range LVDS output interface matches the downstream receiver specifications.

Part Context

The AD9978BCPZ belongs to the AD9978 family of highly integrated CCD signal processors. This series consolidates analog front-end functions and ADC conversion into a single chip to reduce board space and simplify design for digital imaging systems.

Replacement Considerations

Consult the official datasheet for any listed pin-compatible alternatives or updated revisions within the AD9978 family. Verify functional equivalence regarding timing resolution and ADC performance if considering substitutes.
