Product details

Overview

AD9923ABBCZRL from Analog Devices is a CCD signal processor IC integrating a 15-channel vertical driver, 12-bit 36 MHz ADC, correlated double sampler (CDS), 10-bit VGA (6–42 dB), and precision timing generator with <600 ps resolution. It serves as the complete front-end for digital still cameras, handling CCD analog signal conditioning, digitization, and high-accuracy clock generation for vertical/horizontal/substrate timing.

For engineers reviewing the AD9923ABBCZRL datasheet, AD9923ABBCZRL pinout, AD9923ABBCZRL application, or AD9923ABBCZRL equivalent, key selection considerations include its 8 mm × 8 mm CSP_BGA package, −25°C to +85°C operating range, 3-wire serial interface, support for 5-field/10-phase CCDs, and integrated RG/H-driver outputs with programmable edge placement.

Technical Context

The AD9923ABBCZRL implements a Precision Timing™ core synchronized to a 36 MHz CLI master clock, enabling 48-step edge positioning with ~600 ps resolution for RG, H1–H4, HL, SHP, and SHD signals. Its timing engine supports both master mode (generating VD/HD) and slave mode (synchronizing to external VD/HD).

The analog front end integrates black level clamping with 1024-step resolution, CDS with programmable gain (−3 dB to +6 dB), and a 12-bit ADC with guaranteed no missing codes, DNL ±0.5 LSB, and 1.0 LSB_rms total output noise at 6 dB VGA gain. The on-chip 15-channel V-driver operates with VH1/VH2 = +15 V, VL1/VL2 = −7.5 V, and VM1/VM2 = 0 V.

Equivalent & Alternatives

The following parts are listed as comparable options for similar CCD signal processor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AD9923BBCZ	Same silicon die and pinout; differs only in temperature grade (−40°C to +85°C vs. −25°C to +85°C) and packaging (non-RoHS leaded CSP_BGA).	Supports extended industrial temperature range and legacy RoHS-exempt designs.	Select AD9923BBCZ only if extended temp range or non-RoHS compliance is required; AD9923ABBCZRL is preferred for commercial digital cameras.
TDA9979HN/C1	Single-chip solution with integrated 14-bit ADC, but lacks on-chip V-driver; requires external vertical driver and separate timing controller.	Targeted at cost-sensitive broadcast CCD cameras where system partitioning is acceptable.	Choose TDA9979HN/C1 when higher ADC resolution is prioritized over integration; AD9923ABBCZRL reduces BOM count via integrated V-driver and timing generator.

Compared with AD9923BBCZ, AD9923ABBCZRL offers tighter commercial temperature specification and RoHS-compliant packaging; compared with TDA9979HN/C1, it provides full front-end integration-eliminating external V-driver and timing ICs-reducing layout complexity and power delivery points.

FAQ

What is the primary function of the AD9923ABBCZRL in a digital camera system?

The AD9923ABBCZRL serves as the complete CCD analog front end and timing controller. It conditions the CCD analog signal via CDS and VGA, digitizes it with a 12-bit 36 MHz ADC, and generates all necessary CCD clocks - including RG, H1–H4, HL, V1–V13, SUBCK, and VSUB - using its integrated Precision Timing™ core. This eliminates the need for multiple discrete timing and driver ICs in the AD9923ABBCZRL-based design.

Does the AD9923ABBCZRL support both master and slave timing modes?

Yes, the AD9923ABBCZRL supports both master and slave timing modes. In master mode, it generates VD and HD sync pulses from the CLI clock; in slave mode, it accepts external VD and HD inputs and synchronizes its internal timing to them. The SYNC input allows resynchronization during operation, and the device maintains <4 ns jitter on HD/VD edges in slave mode - critical for frame-locked multi-sensor systems using AD9923ABBCZRL.

What are the power supply requirements for the V-driver section of the AD9923ABBCZRL?

The AD9923ABBCZRL V-driver requires five independent supply rails: VDD1/VDD2 (+2.7 V to +3.6 V, logic), VH1/VH2 (+11.5 V to +16.5 V, high-side), VL1/VL2 (−8.5 V to −5.5 V, low-side), VM1/VM2 (−1.5 V to +1.5 V, mid-level), and VLL/VMM for SUBCK. Typical operation uses VH1/VH2 = +15 V, VL1/VL2 = −7.5 V, and VM1/VM2 = 0 V. These rails must be independently filtered and decoupled to maintain timing integrity and minimize crosstalk in the AD9923ABBCZRL's sensitive analog/digital interface.

How does the Precision Timing™ core in the AD9923ABBCZRL achieve <600 ps resolution?

The AD9923ABBCZRL Precision Timing™ core divides the 36 MHz CLI master clock period into 48 discrete edge positions, yielding ~600 ps resolution per step. It uses a high-speed interpolator architecture referenced directly to CLI - not a PLL - ensuring deterministic, low-jitter timing. Edge locations for RG, H1–H4, HL, SHP, and SHD are programmed via six-bit registers mapped to four quadrants of 12 positions each. This architecture enables precise alignment of CCD charge transfer events in the AD9923ABBCZRL without external delay elements.

Can the AD9923ABBCZRL drive CCDs directly without external buffers?

Yes, the AD9923ABBCZRL includes on-chip drivers for RG, HL, and H1–H4 outputs capable of delivering up to 30 mA per channel into 100 pF loads - sufficient to drive typical CCD horizontal inputs directly. However, the 15-channel V-driver outputs (V1–V13) and SUBCK require external level-shifting or buffering for most CCDs due to their multi-rail voltage swing (e.g., −7.5 V to +15 V). The AD9923ABBCZRL's integrated H/RG drivers reduce component count, but vertical timing still relies on properly biased external circuitry interfacing with AD9923ABBCZRL outputs.
