Analog Devices Inc. AD9928BBCZ

Overview

AD9928BBCZ from Analog Devices is a dual-channel, 14-bit CCD signal processor with integrated V-driver and precision timing generator, featuring 60 MHz grade operation (AD9928BBCZ-60), 14-bit/40 MHz ADC, 6 dB–42 dB 10-bit VGA, −3 dB to +6 dB CDS gain, and 390 ps timing resolution at 40 MHz - deployed in high-speed industrial and surveillance camera systems.

For engineers reviewing the AD9928BBCZ datasheet, AD9928BBCZ pinout, AD9928BBCZ application, or AD9928BBCZ equivalent, key selection considerations include dual AFE channel synchronization, LVDS serial output compliance, on-chip 3 V horizontal/RG drivers, 128-ball CSP_BGA package compatibility, and timing core resolution for sub-microsecond CCD clock alignment.

Technical Context

The AD9928BBCZ integrates two independent analog front ends-each with correlated double sampling (CDS), variable gain amplification (VGA), black level clamping, and 14-bit ADC conversion-synchronized by a shared Precision Timing® core supporting 24 vertical clocks and 18 high-voltage V-driver outputs. Its reduced-range LVDS interface delivers serialized pixel data at up to 40 MSPS per channel.

Timing control includes programmable RG, H1–H4, V1–V15, substrate clock (SUBCK), and substrate count (XSUBCNT) signals, all generated from an on-chip crystal oscillator driver and regulated by internal LDOs for 1.8 V core and 3 V I/O compatibility. The device operates across −25°C to +85°C.

Key Specifications

Pinout & Package

AD9928BBCZ uses a 128-ball CSP_BGA package (9 mm × 9 mm, 0.65 mm pitch) with ball map defined in Analog Devices' AD9928 Rev. SpH datasheet, Figure 2 (Ball Map). Pin functions are assigned per functional group: analog inputs (CCDIN_A/B), LVDS data outputs (DOUT0P_A/N_A, DOUT1P_A/N_A, etc.), timing control (RG_A/B, H1A–H4A, V1A–V15), power (LDOIN_A/B, LDOOUT_A/B), and general-purpose outputs (GPO1–GPO7, XSUBCNT).

FAQ

What is the maximum pixel clock rate supported by the AD9928BBCZ?

The AD9928BBCZ supports a 60 MHz grade operation (AD9928BBCZ-60), enabling pixel clock rates up to 60 MHz in high-speed CCD readout configurations. This rating is verified in the AD9928 Rev. SpH datasheet and applies specifically to the AD9928BBCZ variant. The 14-bit ADC operates at up to 40 MSPS per channel, with timing flexibility provided by the Precision Timing® core for synchronization across dual channels.

Does the AD9928BBCZ include an integrated crystal oscillator driver?

Yes, the AD9928BBCZ includes an on-chip driver for external crystal oscillators, as confirmed in the General Description and Functional Block Diagram of the AD9928 Rev. SpH datasheet. This feature eliminates the need for an external crystal buffer and simplifies clock source implementation for the Precision Timing® core and internal clock generation.

Can the AD9928BBCZ drive both interline and frame-transfer CCDs?

Yes, the AD9928BBCZ supports both interline and frame-transfer CCD architectures. Its programmable timing generator provides RG, H, V, substrate clock, and substrate bias control signals, and its 18-channel V-driver accommodates multi-phase vertical transfer requirements. The AD9928BBCZ datasheet explicitly references digital still-image camera applications, which commonly use both CCD types.

What voltage levels do the AD9928BBCZ horizontal and RG drivers support?

The AD9928BBCZ includes on-chip 3 V horizontal and RG drivers, as stated in the FEATURES section of the AD9928 Rev. SpH datasheet. These drivers are designed to directly interface with standard CCD sensors requiring 3 V logic-level timing inputs, eliminating external level-shifting components for those signal paths.

Is the AD9928BBCZ pin-compatible with the AD9920A or AD9990?

No, the AD9928BBCZ is not pin-compatible with the AD9920A or AD9990. While the AD9928BBCZ datasheet notes that its registers are similar to those of AD9920A and AD9990, it uses a unique 128-ball CSP_BGA package and integrates functions (e.g., 18-channel V-driver, dual AFE) absent in those predecessors. Pin mapping and ball assignment differ significantly per the AD9928 Rev. SpH Ball Map.
