Analog Devices Inc. ADDI7100BCPZ

Overview

ADDI7100BCPZ from Analog Devices is a complete 12-bit, 45 MHz CCD signal processor IC designed for analog front-end conditioning of interlaced and progressive-scan CCD outputs. It integrates a correlated double sampler (CDS), 10-bit VGA (6–42 dB gain), optical black clamp, and 12-bit ADC - all operating from a single 3 V supply with 125 mW typical power dissipation. Used in digital still cameras and CCTV imaging systems where high-fidelity pixel-level signal integrity is critical.

For engineers reviewing the ADDI7100BCPZ datasheet, ADDI7100BCPZ pinout, ADDI7100BCPZ application, or ADDI7100BCPZ equivalent, this page delivers verified functional architecture, real-world timing constraints (e.g., 4 ns internal SHP/SHD delay), noise performance (0.8 LSB rms), guaranteed no-missing-codes operation, and precise register-controlled black level clamping behavior per horizontal line.

Technical Context

The ADDI7100BCPZ implements a single-channel CCD signal chain with CDS sampling synchronized to SHP/SHD rising edges, followed by digitally programmable VGA gain (1024-step resolution) and optical black clamp correction applied via DAC feedback during CLPOB-aligned shielded pixel intervals. Its 12-bit ADC uses a 2.0 V full-scale input range referenced between REFT (2.0 V) and REFB (1.0 V).

Internal register control occurs over a 3-wire serial interface (SCK up to 40 MHz, SL/SDATA timing compliant with 10 ns setup/hold), supporting dynamic configuration of gain, clamp level (2048-step resolution), clock polarity, and power-down modes - including full standby (1 mW) and reference standby states.

Key Specifications

Pinout & Package

FAQ

What is the maximum sampling rate supported by the ADDI7100BCPZ?

The ADDI7100BCPZ supports a maximum DATACLK frequency of 45 MHz, enabling pixel-level sampling at 45 MSPS. This rate is validated across the full operating temperature range (−25°C to +85°C) and supply voltage (2.7 V to 3.6 V). The internal pipeline delay is fixed at 15 DATACLK cycles, ensuring deterministic output latency critical for real-time image processing synchronization in the ADDI7100BCPZ.

Does the ADDI7100BCPZ include an integrated correlated double sampler (CDS)?

Yes, the ADDI7100BCPZ integrates a correlated double sampler with configurable gain options (−3 dB, 0 dB, +3 dB, +6 dB) controlled via internal registers. It samples the CCD signal on the rising edges of SHP (reference level) and SHD (data level), with a measured 4 ns internal aperture delay. This CDS stage is essential for removing kTC noise and reset pedestal errors before VGA amplification and ADC conversion in the ADDI7100BCPZ signal chain.

How does the optical black clamp function in the ADDI7100BCPZ?

The optical black clamp in the ADDI7100BCPZ operates during the CLPOB pulse interval aligned with shielded CCD pixels. It compares the ADC output against a user-programmed clamp level (0–511 LSB), filters the error signal, and applies correction via DAC feedback to the ADC input. This closed-loop correction occurs once per horizontal line by default and is critical for suppressing fixed-pattern noise and temperature-induced black level drift in the ADDI7100BCPZ.

What power supply requirements does the ADDI7100BCPZ have?

The ADDI7100BCPZ operates from a single 3.0 V supply (range 2.7 V to 3.6 V) for AVDD, DVDD, and DRVDD. It consumes 125 mW typically in normal operation and drops to 1 mW in full standby mode. Decoupling requires 0.1 µF ceramics on REFT/REFB and bulk capacitance near AVDD/DVDD pins; the exposed thermal pad must be soldered to PCB ground to maintain θJA = 27.7°C/W in the ADDI7100BCPZ.

Is the ADDI7100BCPZ pin-compatible with any other Analog Devices parts?

Yes, the ADDI7100BCPZ is explicitly documented as a pin-compatible upgrade for the AD9945ACPZ. Both share identical 32-lead LFCSP packaging, pin assignments, and register mapping - allowing direct replacement without PCB layout changes. However, the ADDI7100BCPZ adds 12-bit resolution, 45 MSPS capability, and optical black clamping not present in the AD9945ACPZ, making it a functional superset within the same footprint.
