Z8300

The Z8300 is one kind of video system controller and consists of a parallel-to-serial converter which provides a cideo bit stream to on-chip attribute logic.This logic,under control of the attribute inputs,operates on  the bit stream to generate grey scale video.Video outputs from the VSC are of two forms-analog and digital.The digitally encoded outputs implement four video levels:blank,black,grey and white.Identical information is available in analog form via differential outputs(current driven) into a nominal 75 impedance.

The distinctive characteristics of the Z8300 are:(1)100 MHz video dot rate;(2)four-level current driven differential video output;(3)digital video output ECL option;(4)on-board crystal driven oscillator;(5)proportional spacing support(2-17 dots);(6)9-bit dot data parallel input with expansion capability to seventeen bits;(7)buffered and synchronized character clock outputs;(8)background color selection;(9)buffered and synchronized vertical and horizontal sync outputs.

The absolute maximum ratings of the Z8300 can be summarized as:(1)storage temperature:-65 to 150;(2)supply voltage to ground potential continuous:-0.5 to 7.0 V;(3)DC voltage applied to output for high output state:-0.5 V to Vcc;(4)DC input voltage:-0.5 to 5.5 V;(5)DC output current into outputs:30 mA;(6)DC input current:-30 to 5.0 mA.If you want to know more information about Z8300,please download the datasheet in www.seekic.com .
