Analog Devices Inc. ADDI7018BCPZ

Overview

ADDI7018BCPZ from Analog Devices is a dual-channel, 16-bit CCD image signal processor with integrated analog front end (AFE), 75 MHz ADC, 10-bit VGA (6 dB–42 dB), Precision Timing® core (210 ps resolution at 75 MHz), and reduced-range LVDS serial output - designed for HD broadcast and high-speed industrial camera systems.

For engineers reviewing the ADDI7018BCPZ datasheet, ADDI7018BCPZ pinout, ADDI7018BCPZ application, or ADDI7018BCPZ equivalent, key selection criteria include dual-channel CDS/SHA timing precision, 16-bit/75 MHz ADC performance, LVDS data serialization capability, black level clamp programmability, and LFCSP-40 thermal/mechanical suitability for compact imaging modules.

Technical Context

The ADDI7018BCPZ implements two independent AFE channels, each with configurable CDS or SHA sampling, selectable gain settings (−3 dB, 0 dB, +3 dB, +6 dB), and a 10-bit VGA supporting 6 dB to 42 dB linear gain control. Its Precision Timing® core delivers 210 ps clock adjustment resolution at 75 MHz pixel rate, enabling sub-pixel synchronization of sampling edges across both channels.

It integrates a 16-bit, 75 MHz SAR ADC per channel, black level clamping with variable DC offset control, and an LVDS serializer driving four differential pairs (DOUT0P/N through DOUT3P/N) for dual-channel 16-bit data. Configuration occurs via a 3-wire SPI-compatible interface (SDATA, SCK, CLI).

FAQ

What is the primary function of the ADDI7018BCPZ in a camera system?

The ADDI7018BCPZ serves as a dual-channel CCD image signal processor, integrating analog front-end functions (CDS/SHA, VGA, black level clamp), a 16-bit/75 MHz ADC per channel, and a Precision Timing® core. It digitizes and conditions analog outputs from two CCD sensors while enabling sub-pixel clock alignment - essential for HD broadcast and industrial machine vision systems where timing coherence directly affects image fidelity.

Does the ADDI7018BCPZ support both CDS and SHA configurations?

Yes, the ADDI7018BCPZ supports both correlated double sampling (CDS) and sample-and-hold amplifier (SHA) configurations per channel, with selectable gain options of −3 dB, 0 dB, +3 dB, and +6 dB. This flexibility allows optimization for different CCD architectures - CDS for noise reduction in interline sensors, SHA for global shutter applications - all programmable via the 3-wire serial interface.

What is the significance of the 210 ps timing resolution in the ADDI7018BCPZ?

The 210 ps timing resolution in the ADDI7018BCPZ's Precision Timing® core enables precise adjustment of CDS and SHA sampling clocks at 75 MHz pixel rates. This allows sub-pixel edge placement control, reducing fixed-pattern noise and timing-induced artifacts in dual-sensor systems - a capability not present in earlier variants like the AD9978ABCPZ, which offers only 1 ns resolution.

Can the ADDI7018BCPZ be used with non-CCD image sensors?

No, the ADDI7018BCPZ is specifically architected for charge-coupled device (CCD) sensors, with analog input structure, CDS/SHA timing logic, and reset noise rejection features optimized for CCD output characteristics. It does not support CMOS image sensor interfaces such as MIPI CSI-2 or parallel LVCMOS timing protocols, and lacks on-chip PLLs or serializers required for modern CMOS sensor integration.

What package type and thermal characteristics does the ADDI7018BCPZ use?

The ADDI7018BCPZ uses a 6 mm × 6 mm, 40-lead LFCSP package with an exposed thermal pad. This package supports junction-to-board thermal resistance of ≤25°C/W under standard PCB layout (2 oz copper, 4 thermal vias), enabling reliable operation from −25°C to +85°C ambient - verified per the ADDI7018BCPZ datasheet Rev. Sp0 thermal characterization.
