ADDI9020

60 MHz的CCD信号处理器， V型驱动器和精确定时发生器 60 MHz CCD Signal Processor with V-Driver and Precision Timing Generator

Product Details

The is a complete 60 MHz front-end solution for digital still cameras and other charge-coupled device CCD imaging applications. The ADDI9020 includes the analog front end AFE, a fully programmable timing generator TG, and a 12-channel V-driver. A _Precision Timing_® core allows adjustment of high speed clocks with approximately 260 ps resolution at 60 MHz operation.

The on-chip V-driver supports up to 12 channels for use with multifield CCDs.

The analog front end includes black level clamping, CDS, VGA, and a 12-bit ADC. The timing generator and V-driver provide all the necessary CCD clocks: RG, H-clocks, vertical clocks, sensor gate pulses, a substrate clock, and substrate bias control. The internal registers are programmed using a 3-wire serial interface.

Packaged in a 7 mm × 7 mm CSP_BGA, the ADDI9020 is specified over an operating temperature range of −25°C to +85°C.
