Product details

Overview

AD9927BBCZRL from Analog Devices is a 14-bit CCD signal processor integrating a 18-channel vertical driver, precision timing generator, correlated double sampler (CDS), 10-bit VGA (6–42 dB), and 14-bit 40 MHz ADC - designed for digital still camera CCD readout systems requiring high-resolution analog signal conditioning and sub-400 ps clock edge placement.

For engineers reviewing the AD9927BBCZRL datasheet, AD9927BBCZRL pinout, AD9927BBCZRL application, or AD9927BBCZRL equivalent, this device serves as a complete front-end solution for advanced CCD sensors with programmable V-clock sequencing, on-chip 3 V horizontal/RGB drivers, black level clamping, and synchronized exposure control via GPOs and SYNC interface.

Technical Context

The AD9927BBCZRL implements a unified Precision Timing core operating at 40 MHz CLI input, dividing each clock period into 64 discrete edge positions (~390 ps resolution) to program RG, H1–H8, SHP/SHD, and XV outputs with deterministic phase alignment. Its analog front end combines CDS with selectable gain (−3 dB to +6 dB), a 10-bit VGA, and a 14-bit ADC with ±0.5 LSB DNL and 0.3% peak nonlinearity.

It supports dual-mode operation: master mode (generating HD/VD from CLI) or slave mode (synchronizing to external HD/VD), with full register control over vertical sequences (up to 24 XV signals), substrate clock (SUBCK), field counters, and shutter timing using eight general-purpose outputs (GPO1–GPO8).

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
AD9945KCPZ-REEL	12-bit ADC, no integrated V-driver, requires external timing logic - lacks Precision Timing core and XV outputs.	Suitable only for simpler 3-field CCDs without substrate clock or multi-level V-clock requirements.	Select when lower cost and reduced feature set are acceptable, and external timing generation is already implemented.
TDC1304IPHP	14-bit ADC + CDS + VGA but no timing generator or V-driver - purely analog front-end with SPI interface only.	Requires separate FPGA/CPLD for all CCD clocks and GPO control - increases design complexity and board space.	Choose if existing system uses custom timing logic and only analog signal chain upgrade is needed.

Compared with AD9945KCPZ-REEL and TDC1304IPHP, the AD9927BBCZRL uniquely integrates full CCD timing generation, 18-channel V-driving, and precision sub-400 ps clock placement - making it the only single-chip solution for advanced 5-field CCDs requiring coordinated vertical transfer, substrate control, and exposure synchronization.

FAQ

What is the maximum clock frequency supported by the AD9927BBCZRL CLI input?

The AD9927BBCZRL supports a maximum CLI input frequency of 40 MHz, which serves as the master reference for its Precision Timing core. At this rate, the internal timing engine achieves ~390 ps edge resolution across 64 programmable positions per clock cycle. This frequency directly sets the pixel rate and determines the maximum achievable frame rate and horizontal resolution in master mode operation of the AD9927BBCZRL.

Does the AD9927BBCZRL include an integrated voltage regulator for its analog supply?

Yes, the AD9927BBCZRL includes an internal LDO regulator with dedicated LDOIN, LDOOUT, LDO3P2EN, and LDO1P8EN pins. It can generate regulated 3.2 V and 1.8 V outputs from a 3.0 V to 3.6 V input, supporting AVDD and DVDD domains. This eliminates the need for external regulators in many digital still camera designs and improves power supply rejection - a key capability confirmed in the AD9927BBCZRL datasheet's power section.

How many vertical clock outputs does the AD9927BBCZRL provide, and what are their voltage level configurations?

The AD9927BBCZRL provides 15 dedicated vertical clock outputs (V1A–V15) plus SUBCK, totaling 16 V-clock signals. V1A–V6 are 3-level outputs (supporting VH/VM/VL), while V7–V15 and SUBCK are 2-level outputs (VH/VL). Each group uses independent supply rails (VH1/VH2, VL1/VL2, VM1/VM2, VLL, VMM), enabling precise waveform shaping for advanced 5-field CCD architectures - a defining specification of the AD9927BBCZRL.

Can the AD9927BBCZRL operate without an external crystal oscillator?

Yes, the AD9927BBCZRL can operate without an external crystal by accepting a 40 MHz clock directly on the CLI pin. It also includes an on-chip crystal driver (CLO output) that, when paired with an external crystal between CLI and CLO, forms a self-contained oscillator. This dual-mode clocking flexibility - external clock or crystal-based - is explicitly supported and documented for the AD9927BBCZRL in its functional description and pin configuration tables.

What is the purpose of the GPO pins on the AD9927BBCZRL, and how are they configured?

The AD9927BBCZRL includes eight general-purpose outputs (GPO1–GPO8) that are fully programmable via internal registers to generate timed pulses for mechanical shutter actuation, flash strobe triggering, or system-level synchronization. Each GPO supports adjustable pulse width, delay, and polarity, and can be linked to internal counters or SYNC events - making them essential for exposure control in digital still camera applications using the AD9927BBCZRL.
