Quad-Channel, 16-Bit CCD Signal
Processor with Precision Timing Core
Data Sheet
ADDI7015
FEATURES
GENERAL DESCRIPTION
4 independent AFE channels
The ADDI7015 is a highly integrated, quad-channel, CCD
signal processor for high speed digital imaging applications.
Each channel is specified at pixel rates of up to 65 MHz and
consists of a complete analog front end (AFE) with analog-to-
digital conversion. The Precision Timing® core allows adjust-
ment of the correlated double sampler (CDS) and sample-and-
hold amplifier (SHA) clocks with 240 ps resolution at 65 MHz
operation. There are eight independent horizontal clock outputs
to support a variety of CCD timing requirements. The
ADDI7015 also features a programmable ISATG for vertical
timing generation.
1.8 V analog and digital core supply voltage
Complete on-chip ISATG timing generator with 16 XV
outputs and 4 general-purpose outputs (GPO)
Differential analog inputs
CDS or SHA (CDS bypass) with 7 gain settings
0 dB to 36 dB, 10-bit variable gain amplifier (VGA)
16-bit, 65 MSPS analog-to-digital converter (ADC)
Precision Timing core with 240 ps resolution at 65 MHz
8 programmable H-clock outputs
On-chip sync generator with external sync input
8 mm × 8 mm CSP_BGA package with 0.65 pitch
Each analog front end includes black level clamping, a CDS, a
VGA, and a 65 MSPS, 16-bit analog-to-digital converter (ADC).
Operation is programmed using a 4-wire serial interface.
APPLICATIONS
Industrial cameras
Surveillance cameras
Medical imaging
Professional photography
Packaged in a space-saving, 8 mm × 8 mm, CSP_BGA, the
ADDI7015 is specified over an operating temperature range of
−25°C to +85°C.
