Data Sheet
AD9928
FEATURES
GENERAL DESCRIPTION
60 MHz grade available (AD9928BBCZ-60)
Registers similar to AD9920A and AD9990
Timing generator with 18-channel V-driver
The AD9928 is a highly integrated CCD signal processor for
digital still-image camera applications. It includes a dual analog
front end with analog-to-digital conversion, combined with a full-
Serial data output with reduced range LVDS interface
1.8 V dual AFE core
Internal LDO regulators for compatibility with 3 V systems
Correlated double sampler (CDS) with −3 dB, 0 dB, +3 dB,
and +6 dB gain
6 dB to 42 dB, 10-bit variable gain amplifier (VGA)
14-bit, 40 MHz analog-to-digital converter (ADC)
Black level clamp with variable level control
Precision Timing core with ~390 ps resolution at 40 MHz
On-chip 3 V horizontal and RG drivers
function, programmable timing generator and an 18-channel
vertical driver (V-driver) for a 2-channel output CCD. The timing
generator is capable of supporting up to 24 vertical clock signals
internally, and the on-chip V-driver supports up to 18 high voltage
outputs. A Precision Timing® core allows adjustment of high speed
clocks with approximately 390 ps resolution at 40 MHz operation.
The AD9928 also contains seven general-purpose outputs, which
can be used for shutter and system functions.
Each analog front end includes black level clamping, CDS,
VGA, and a 14-bit ADC. The timing generator provides all the
necessary CCD clocks: RG, H-clocks, V-clocks, sensor gate
pulses, substrate clock, and substrate bias control.
General-purpose outputs (GPOs) for shutter support
On-chip driver for external crystal
128-ball CSP_BGA package, 9 mm × 9 mm, 0.65 mm pitch
The AD9928 is specified over an operating temperature range
of −25°C to +85°C.
