Analog Devices Inc. ADDI9023BBCZRL

Overview

ADDI9023BBCZRL from Analog Devices is a 12-channel CCD vertical driver IC with eight three-level and four two-level output drivers, supporting −9.5 V to +15.5 V output voltage swing, 3 nF load drive capability per channel, and operation from −25°C to +85°C. It serves as the timing interface between CCD image sensors and system timing generators in high-resolution imaging systems.

For engineers reviewing the ADDI9023BBCZRL datasheet, ADDI9023BBCZRL pinout, ADDI9023BBCZRL application, or ADDI9023BBCZRL equivalent, key selection criteria include multi-level output polarity control, substrate clock (SUBCK) integration, CSP_BGA package thermal performance (θJA = 46°C/W), and compatibility with 1.6 V–3.6 V logic interfaces.

Technical Context

The ADDI9023BBCZRL implements dedicated three-level (V1A–V5) and two-level (V6–V9) vertical transfer clock outputs driven by combinational logic of XVx and XSGx inputs, with precise delay matching (tPLM/tPML = 37 ns typ) and defined rise/fall times under 3 nF load. Its SUBCK channel operates independently with separate VLL/VH supplies and 45 ns rise/fall times into 1 nF.

Power sequencing requires strict ordering: VDD first (1.6–3.6 V), then VH (+11–15.5 V), then VL/VLL (−9.5–−5.5 V), followed by VDREN assertion. All analog supplies (VH, VM, VL, VLL, VMM) are externally decoupled with 0.1 µF + bulk capacitance, and ground pins (VSS, VM, VMM) share a low-impedance plane.

FAQ

What is the primary function of the ADDI9023BBCZRL in a CCD imaging system?

The ADDI9023BBCZRL functions as a 12-channel vertical driver IC that generates precisely timed three-level (V1A–V5) and two-level (V6–V9) transfer clocks for CCD image sensors, plus an independent substrate clock (SUBCK). It translates digital timing signals from a system controller into high-voltage analog waveforms required to shift accumulated charge vertically through the CCD array. The ADDI9023BBCZRL enables accurate charge transfer with minimal smear or distortion.

Does the ADDI9023BBCZRL support both positive and negative output voltage rails?

Yes, the ADDI9023BBCZRL supports a full bipolar output voltage range from −9.5 V to +15.5 V across its vertical driver outputs (V1A–V9) and SUBCK channel. This is achieved using separate supply pins: VH (+11–15.5 V), VL (−9.5–−5.5 V), VLL (−9.5–−5.5 V, dedicated to SUBCK), and VM (−1.5–+1.5 V, midsupply reference). The ADDI9023BBCZRL uses these rails to synthesize three-level (VH/VM/VL) and two-level (VM/VL or VH/VLL) output states.

What is the recommended power-up sequence for the ADDI9023BBCZRL?

The ADDI9023BBCZRL requires a strict power-up sequence to prevent latch-up or output contention: (1) apply VDD (1.6–3.6 V) and stabilize logic inputs; (2) apply VH (+11–15.5 V); (3) apply VL and VLL (−9.5–−5.5 V); (4) assert VDREN high to enable outputs. This sequence is documented in the ADDI9023BBCZRL datasheet Figure 7 and ensures safe biasing of internal level-shifters before enabling high-voltage outputs.

How does the ADDI9023BBCZRL implement three-level output logic for V1A–V5?

The ADDI9023BBCZRL implements three-level output logic for V1A–V5 by combining two digital inputs per channel: one vertical phase input (XV1–XV5) and one shift gate input (XSG1–XSG8). As shown in Tables 6–13 of the ADDI9023BBCZRL datasheet, each pair determines whether the output settles at VH, VM, or VL. For example, V1A outputs VH when XV1 = L and XSG1 = L, VM when XV1 = L and XSG1 = H, and VL when XV1 = H regardless of XSG1 state.

What package type and thermal characteristics does the ADDI9023BBCZRL use?

The ADDI9023BBCZRL uses a 40-ball Chip Scale Package Ball Grid Array (CSP_BGA), 6 mm × 6 mm, 0.65 mm pitch, per JEDEC MO-225 (with height/thickness exceptions). Its thermal resistance is θJA = 46°C/W under worst-case PCB mounting conditions. This package enables high-density placement in space-constrained imaging modules while maintaining thermal performance suitable for continuous operation in industrial and medical environments.
