Dual-Channel, 14-Bit CCD Signal Processor  
with Precision Timing™ Core  
AD9942  
FEATURES  
GENERAL DESCRIPTION  
40 MHz correlated double sampler (CDS)  
The AD9942 is a highly integrated dual-channel CCD signal  
0 dB to 18 dB, 9-bit variable gain amplifier (VGA)  
40 MSPS analog-to-digital converter (ADC)  
Optical black clamp (CLPOB) with variable level control  
Complete on-chip timing driver  
Precision Timing core with <550 ps resolution  
On-chip 3 V horizontal and RG drivers  
4-phase H-clock mode  
processor for digital still camera applications. Each channel is  
specified at pixel rates of up to 40 MHz. The AD9942 consists of  
a complete analog front end with analog-to-digital conversion,  
combined with a programmable timing driver. The Precision  
Timing core allows high speed clocks to be adjusted with  
550 ps resolution.  
The analog front end uses black level clamping and includes a  
VGA, a 40 MSPS ADC, and a CDS. The timing driver provides  
the high speed CCD clock drivers for RG_A and RG_B, as well  
as the H1A to H4A and H1B to H4B outputs. The 6-wire serial  
interface is used to program the AD9942.  
100-lead, 9 mm × 9 mm, CSP_BGA package  
APPLICATIONS  
Signal processor for dual-channel CCD outputs  
Digital still cameras  
Digital video cameras  
High speed digital imaging applications  
Available in a space-saving, 9 mm × 9 mm, CSP_BGA package,  
the AD9942 is specified over an operating temperature range of  
−25°C to +85°C.
