Dual-Channel, 16-Bit HD Image Signal Processor with Precision Timing Core ADDI7018 Data Sheet FEATURES GENERAL DESCRIPTION Pin-compatible with the AD9978A Dual AFE channels 1.8 V analog and digital core supply voltage Serial data output with reduced range LVDS outputs Differential analog inputs CDS or SHA configuration (CDS bypass) with −3 dB, 0 dB, +3 dB, and +6 dB gain 6 dB to 42 dB, 10-bit variable gain amplifier (VGA) 16-bit, 75 MHz analog-to-digital converter (ADC) Black level clamp with variable level control Precision Timing core with 210 ps resolution at 75 MHz The ADDI7018 is a highly integrated, dual-channel, chargecoupled device (CCD) signal processor for high speed digital video camera applications. Each channel is specified at pixel rates of up to 75 MHz and consists of a complete analog front end (AFE) with ADC conversion. The Precision Timing® core allows adjustment of the correlated double sampler (CDS) and sample-and-hold amplifier (SHA) clocks with 210 ps resolution at 75 MHz operation. The ADDI7018 also contains a reduced range low voltage differential signaling (LVDS) interface for the dual-channel data outputs. Each analog front end includes black level clamping, a CDS, a VGA, and a 75 MHz, 16-bit analog-to-digital converter (ADC). Operation is programmed using a 3-wire serial interface. APPLICATIONS HD broadcast cameras High speed industrial cameras Professional digital cameras Digital copiers Packaged in a space-saving, 6 mm × 6 mm, 40-lead LFCSP, the ADDI7018 is specified over an operating temperature range of −25°C to +85°C.
