Viewing:

Overview

  • 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
  • Dual AFE channels
  • Pin- compatible with AD9978A
  • 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 @ 75 MHz

The ADDI7018 is a highly integrated, dual-channel, charge-coupled 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.

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.
