AD9978集成電路（IC）的模擬前端（AFE）規(guī)格書PDF中文資料

AD9978屬于集成電路（IC）的模擬前端（AFE）。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD9978模擬前端（AFE）模擬前端 (AFE) 是一種用于信號調(diào)節(jié)的半導(dǎo)體器件，由模擬放大器、運(yùn)算放大器、濾波器和集成電路構(gòu)成。這種可配置功能塊能連接各種傳感器。分辨率范圍從 8 位至 42 位不等，通道數(shù)范圍為 1 至 256 個。

GENERAL DESCRIPTION

The AD9978 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 and consists of a complete analog front end with ADC conversion. The Precision Timing? core allows adjustment of the correlated double sampler (CDS) and sample-and-hold amplifier (SHA) clocks with 240 ps resolution at 65 MHz operation. The AD9978 also contains a reduced range, low voltage differential signaling (LVDS) interface for the dual-channel data outputs.
