AD9979BCPZRL

Overview

The AD9979BCPZRL is a highly integrated CCD signal processor manufactured by Analog Devices Inc. It operates with a 1.8 V analog and digital core supply voltage and supports pixel rates up to 65 MHz. The device features a 14-bit, 65 MSPS analog-to-digital converter (ADC) within its analog front end. Key functional blocks include a correlated double sampler (CDS) with selectable gain settings of –3 dB, 0 dB, +3 dB, and +6 dB, alongside a 10-bit variable gain amplifier (VGA) providing 6 dB to 42 dB gain control. The component includes a black-level clamp with variable level control and an on-chip Precision Timing core offering 240 ps resolution at 65 MHz operation. It provides complete timing generation for CCD drivers, including 3 V horizontal and RG drivers, and interfaces via a 3-wire serial bus. The part is housed in a 48-lead, 7 mm × 7 mm LFCSP package.

Feature Summary

• Integrates a complete analog front end with a 14-bit ADC, CDS, VGA, and black-level clamp for high-speed digital video processing.
• Features a Precision Timing core that allows fine adjustment of high-speed clocks with approximately 240 ps resolution at 65 MHz operation.
• Includes on-chip output drivers capable of directly driving CCD inputs for RG, HL, and H1 to H4 signals.
• Supports flexible timing generation through programmable edge locations and multiple HCLK modes controlled via a 3-wire serial interface.

Applications

• Professional HDTV camcorders
• Professional and high-end digital cameras
• Broadcast cameras
• Industrial high-speed cameras

Procurement Notes

Verify the specific ordering suffix RL against the manufacturer's current documentation to confirm reel packaging specifications. Confirm availability status directly with authorized distributors or the manufacturer, as supply conditions may vary. Ensure the component meets RoHS compliance requirements relevant to your region before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring a single-chip solution for CCD signal processing up to 65 MHz. Ensure the system design accommodates the 1.8 V core supply and 3.3 V driver supplies. Verify that the 48-lead LFCSP package footprint aligns with the PCB layout constraints and thermal management requirements for the operating temperature range of -25°C to +85°C.

Part Context

The AD9979 belongs to the Analog Devices CCD Signal Processor family, designed specifically for high-performance imaging systems. It consolidates functions typically distributed across multiple chips into a single integrated circuit, reducing board space and complexity. The Precision Timing technology distinguishes it by allowing precise synchronization of sampling edges relative to the master clock.

Replacement Considerations

Consult the official datasheet for the AD9979 to identify any officially listed pin-compatible or functionally equivalent replacement parts. Verify that any substitute maintains the same 14-bit resolution, 65 MHz speed, and 48-lead LFCSP package dimensions.
