Product details
Overview
AD9824KCPZRL from Analog Devices is a complete 14-bit, 30 MSPS CCD signal processor IC designed for high-fidelity analog signal conditioning in interlaced and progressive-scan CCD imaging systems. It integrates correlated double sampling (CDS), 6-bit pixel gain amplifier (PxGA®), 10-bit variable gain amplifier (VGA), black-level clamp, and ADC - all operating from a single 3 V supply with 153 mW typical power consumption.
For engineers reviewing the AD9824KCPZRL datasheet, AD9824KCPZRL pinout, AD9824KCPZRL application, or AD9824KCPZRL equivalent, key selection considerations include its 48-lead LFCSP package, 2 dB–36 dB VGA gain range with 1024-step resolution, 14-bit DNL ±0.5 LSB (typ), CCD-mode timing compliance, and support for seven PxGA color steering modes including Bayer mosaic separate and interlace.
Technical Context
The AD9824KCPZRL implements a single-channel CCD signal chain with CDS sampling synchronized to SHP/SHD rising edges (3 ns internal aperture delay), followed by programmable PxGA gain per pixel group, VGA with linear-in-dB response, and DC-coupled optical black clamping referenced to user-configurable 0–1020 LSB levels. Its 3-wire serial interface supports register readback and simultaneous multi-register update on SL rising edge.
It supports three operational modes: CCD mode (full signal chain), AUX1 mode (CCDIN bypassed, auxiliary input with full VGA), and AUX2 mode (reduced VGA range 0–18 dB, 512-step resolution). All modes maintain 30 MHz maximum DATACLK rate, 9-cycle pipeline latency, and 2.0 V ADC full-scale input range with straight-binary coding.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution & Speed | 14-bit ADC at 30 MSPS - delivers full 14-bit no-missing-codes performance with 0.1% peak nonlinearity at 500 mV input under 12 dB gain. |
| VGA Gain Range | 2 dB to 36 dB in 1024 steps - enables precise analog gain control across wide dynamic range while maintaining monotonicity and ±0.5 dB gain accuracy at extremes. |
| PxGA Gain Control | –2.5 dB to +9.5 dB in 64 steps per channel - supports pixel-level color gain correction for Bayer and other CFA patterns via HD/VD-synchronized multiplexing. |
| Power Consumption | 153 mW @ 3 V - optimized for portable and thermally constrained imaging systems; drops to 5 mW in standby and 0.5 mW in total shutdown. |
| Input Signal Handling | Supports 1.0 Vp-p max CCD input before saturation and 500 mV reset transient tolerance - ensures robust operation with real-world CCD output transients. |
| Reference & Noise | 2.0 V top / 1.0 V bottom reference; 2.0 LSBrms total output noise - provides stable 2 V full-scale ADC range and low-noise digitization critical for scientific-grade image fidelity. |
Pinout & Package
AD9824KCPZRL is housed in a space-saving 48-lead LFCSP (Lead Frame Chip Scale Package) with exposed paddle for thermal management (θJA = 26°C/W on 4-layer PCB). Pin 1 identifier located at top-left corner of top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D0–D13 | Digital data outputs (LSB to MSB) | 14-bit straight-binary parallel output latched on DATACLK; D0 (Pin 47) and D13 (Pin 12) define data bus boundaries. |
| SHP / SHD | CDS sampling clocks | Rising-edge triggered inputs controlling reference-level (SHP) and data-level (SHD) sampling; 3 ns internal aperture delay ensures precise timing alignment. |
| CLPOB / CLPDM | Optical black and input clamp clocks | Enable line-rate black-level correction during shielded pixels; CLPOB placement ≥20 pixels wide minimizes clamp noise. |
| HD / VD | Color steering sync inputs | Drive PxGA gain selection logic for mosaic, interlace, or user-defined color filter array patterns; updated internally on SHP rising edge. |
| SCK / SL / SDATA | 3-wire serial interface | Asynchronous SPI-like interface supporting register write/read; SL rising edge triggers simultaneous update of loaded registers. |
| CCDIN / AUX1IN / AUX2IN | Analog signal inputs | Primary CCD input (Pin 30); dual auxiliary inputs (Pins 34, 36) enable flexible signal routing in AUX modes. |
| VRT / VRB | ADC reference decoupling | Provide low-noise 2.0 V / 1.0 V reference points; require dedicated 0.1 µF ceramic decoupling per pin for optimal DNL performance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated CDS + PxGA + VGA + Clamp + ADC | Eliminates need for discrete signal chain components - reduces board area, BOM count, and timing skew between stages. |
| Seven PxGA color steering modes | Hardware-accelerated gain mapping for Bayer (mosaic separate, interlace), 3-color, 4-color, VD-selected, and mosaic repeat CFA layouts - offloads white balance computation from host processor. |
| Programmable optical black clamp | Adjustable clamp level (0–1020 LSB in 256 steps) with closed-loop correction applied via integrated 8-bit DAC - maintains consistent black level across temperature and gain changes. |
| Single 3 V supply operation | Unifies analog, digital, and driver rail requirements - simplifies power design and eliminates level-shifting between domains. |
| Low-power standby and shutdown | 5 mW standby and 0.5 mW total shutdown modes with 1 ms / 3 ms recovery - enables rapid power cycling in battery-powered imaging devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCD signal processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9826KCPZRL | 2-channel architecture, identical 14-bit/30 MSPS per channel, same LFCSP-48 package, but adds dual-input mux and independent PxGA per channel. | Required for dual-CCD or stereo imaging systems; not suitable for single-channel cost-sensitive designs. | Select when simultaneous processing of two independent CCD outputs is needed - no layout change required due to pin-compatible footprint. |
| TDC1304IPWPR | 16-bit, 20 MSPS, integrated PGA + CDS + ADC, but lacks PxGA, optical black clamp, and serial register interface; uses parallel control pins. | Targeted at simpler monochrome industrial sensors where per-pixel color gain and adaptive black-level correction are unnecessary. | Choose for lower-resolution, lower-cost monochrome applications where 16-bit resolution outweighs missing CCD-specific features. |
Compared with AD9824KCPZRL, AD9826KCPZRL adds dual-channel capability at identical speed/resolution but increases complexity and cost, while TDC1304IPWPR offers higher bit depth at reduced speed and omits critical CCD-specific functions like PxGA and optical black clamping - making AD9824KCPZRL the optimal choice for high-fidelity single-channel color CCD systems.

FAQ
What is the maximum clock rate supported by the AD9824KCPZRL?
The AD9824KCPZRL supports a maximum DATACLK, SHP, and SHD clock rate of 30 MHz. This enables full 30 MSPS sampling of CCD output signals while maintaining guaranteed timing margins, including 13 ns minimum high/low pulsewidth for DATACLK and 5 ns minimum pulsewidth for SHP/SHD. Operation above 30 MHz is not characterized and may result in degraded DNL or missing codes.
Does the AD9824KCPZRL support multiple CCD color filter array types?
Yes, the AD9824KCPZRL supports seven programmable PxGA color steering modes - including mosaic separate (Bayer progressive), interlace (Bayer interlaced), 3-color, 4-color, VD selected, mosaic repeat, and user-specified - all configured via the Control Register. Each mode synchronizes PxGA gain selection to HD/VD timing, enabling hardware-based white balance correction without host CPU intervention.
How does the optical black clamp function in the AD9824KCPZRL?
The AD9824KCPZRL implements a closed-loop optical black clamp that samples the ADC output during CLPOB-active periods (optical black pixels), compares it to a user-programmed reference level (0–1020 LSB), and applies correction via an internal 8-bit DAC. This loop removes residual offsets and tracks low-frequency black-level drift, ensuring stable DC baseline across temperature and gain settings - critical for quantitative imaging accuracy.
What power supply configuration is required for the AD9824KCPZRL?
The AD9824KCPZRL operates from a single 3 V supply (2.7 V to 3.6 V) for AVDD, DVDD, and DRVDD rails. It requires separate analog (AVSS) and digital (DVSS, DRVSS) ground planes, with three AVSS pins (Pins 25, 26, 35) and two DVSS pins (Pins 15, 41) for optimal noise isolation. Decoupling capacitors (0.1 µF ceramic) must be placed near each VDD/VSS pair and at VRT/VRB pins.
Can the AD9824KCPZRL be used with non-CCD analog video sources?
Yes, the AD9824KCPZRL supports AUX1 and AUX2 modes for processing standard analog video signals. In AUX1 mode, AUX1IN accepts 1.0 Vp-p input with full 2 dB–36 dB VGA gain; in AUX2 mode, AUX2IN supports 0–18 dB VGA gain with 512-step resolution. Both modes retain CDS disable, black-level clamp, and 14-bit digitization - making AD9824KCPZRL adaptable beyond CCD-specific use cases.
