Dual-Channel, 14-Bit, CCD Signal  
Processor with Precision TimingCore  
AD9974  
FEATURES  
GENERAL DESCRIPTION  
1.8 V analog and digital core supply voltage  
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 analog-to-digital converter (ADC)  
Black level clamp with variable level control  
Complete on-chip timing generator  
The AD9974 is a highly integrated, dual-channel CCD signal  
processor for high speed digital video camera applications. Each  
channel is specified at pixel rates of up to 65 MHz. The AD9974  
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 approximately 240 ps resolution at 65 MHz operation.  
Precision Timing core with 240 ps resolution @ 65 MHz  
On-chip 3 V horizontal and RG drivers  
100-lead, 9 mm × 9 mm, 0.8 mm pitch, CSP_BGA package  
Internal LDO regulator circuitry  
Each 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 the RG_A, RG_B, H1_A to H4_A,  
and H1_B to H4_B outputs. A 3-wire serial interface is used to  
program each channel of the AD9974.  
APPLICATIONS  
Available in a space-saving, 9 mm × 9 mm, CSP_BGA package,  
the AD9974 is specified over an operating temperature range of  
−25°C to +85°C.
