Analog Devices Inc. ADDI7100BCPZRL

Overview

ADDI7100BCPZRL from Analog Devices is a complete 12-bit, 45 MHz CCD signal processor IC integrating correlated double sampling (CDS), 10-bit variable gain amplifier (6 dB to 42 dB), optical black clamp, and ADC in a single 32-lead LFCSP. It conditions interlaced/progressive scan CCD outputs for digital still cameras and camcorders, delivering guaranteed no-missing-codes performance with 0.8 LSB_rms total output noise at 6 dB gain.

For engineers reviewing the ADDI7100BCPZRL datasheet, ADDI7100BCPZRL pinout, ADDI7100BCPZRL application, or ADDI7100BCPZRL equivalent, this page details its CDS timing accuracy (±0.5 dB gain error), VGA monotonicity, 3-wire serial interface register mapping, and system-level noise performance under 3 V single-supply operation.

Technical Context

The ADDI7100BCPZRL implements a single-channel analog front-end optimized for CCD pixel readout: its CDS uses SHP/SHD rising-edge sampling with 4 ns internal delay and supports −3 dB to +6 dB programmable gain; the 10-bit VGA provides 1024-step monotonic gain control via serial interface, with gain equation VGA Gain (dB) = (VGA Code × 0.0358) + 5.4 dB.

Its 12-bit ADC features 2.0 V full-scale input range, ±0.5 LSB differential nonlinearity, and 15-cycle pipeline latency; the optical black clamp operates during CLPOB-aligned shielded pixels, using a DAC-based correction loop updated per horizontal line with 2048-step resolution and configurable settling speed.

FAQ

What is the absolute maximum supply voltage rating for ADDI7100BCPZRL?

The ADDI7100BCPZRL has an absolute maximum analog/digital supply rating of −0.3 V to +3.9 V relative to respective ground pins (AVSS, DVSS, DRVSS). Exceeding these limits may cause permanent damage. Operating voltage must remain within 2.7 V to 3.6 V for functional specification compliance, as verified in Table 1 of the Rev. F datasheet.

Does ADDI7100BCPZRL support both interlaced and progressive scan CCDs?

Yes, ADDI7100BCPZRL is explicitly designed for both interlaced and progressive scan area CCD arrays, as stated in the General Description section. Its CDS architecture, timing flexibility (SHP/SHD edge alignment), and 45 MHz sampling rate accommodate field-based and frame-based readout schemes without modification.

How is the optical black clamp function configured in ADDI7100BCPZRL?

The optical black clamp is enabled/disabled via Register 0x00 Bit 2 (CLAMP_EN). When enabled, it uses CLPOB pulses aligned with CCD shielded pixels to update a DAC-based correction loop. Clamp level is set in Register 0x04 with 2048-step resolution, and settling speed is adjustable via FASTCLAMP (Bit 3) and FASTUPDATE (Bit 4) bits.

What is the purpose of the PBLK pin on ADDI7100BCPZRL?

The PBLK (preblanking) pin on ADDI7100BCPZRL controls blanking behavior during dummy pixel intervals. When asserted, it forces digital outputs to zero (if PBLK_LVL = 0) or to the programmed clamp level (if PBLK_LVL = 1), preventing invalid pixel data from propagating to downstream image processors. It is optional and may be tied low if unused.

Can ADDI7100BCPZRL operate from a single 3 V supply without separate analog/digital rails?

Yes, ADDI7100BCPZRL operates from a single 3 V supply applied to AVDD, DVDD, and DRVDD simultaneously. The datasheet specifies normal operation at AVDD = DVDD = DRVDD = 3 V, with 2.7 V to 3.6 V tolerance. Separate supplies are optional for noise isolation but not required for functionality.
