Data Sheet
AD9970
FEATURES
GENERAL DESCRIPTION
1.8 V analog and digital core supply voltage
The AD9970 is a highly integrated CCD signal processor for
Serial data link with reduced range LVDS outputs
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, 65 MHz ADC
high speed digital video camera applications. Specified at pixel
rates of up to 65 MHz, the AD9970 consists of a complete analog
front end with analog-to-digital conversion combined with a
programmable timing driver. The Precision Timing core allows
adjustment of high speed clocks with 240 ps resolution at
65 MHz operation. The AD9970 also contains a reduced range
LVDS interface for data outputs.
Black level clamp with variable level control
Complete on-chip timing generator
Precision Timing core with 240 ps resolution at 65 MHz
On-chip, 3 V horizontal and RG drivers
5 mm × 5 mm, 32-lead LFCSP_VQ
The analog front end includes black level clamping, CDS, VGA,
and a 65 MSPS, 14-bit ADC. The timing driver provides the high
speed CCD clock drivers for RG, HL, and H1 to H4. Operation
is programmed using a 3-wire serial interface.
APPLICATIONS
Professional HDTV camcorders
Professional/high end digital cameras
Broadcast cameras
Packaged in a space-saving 5 mm × 5 mm, 32-lead LFCSP_VQ,
the AD9970 is specified over an operating temperature range of
−25°C to +85°C.
Industrial high speed cameras
High speed data acquisition systems
