Sharp LZ93N61 Datasheet

LZ93N61

DESCRIPTION

The LZ93N61 is a CMOS timing generator LSI which provides timing pulses used to drive a

CCD

area sensor, in combination with the SSG

LSI (LZ93NI 9, LZ93B53).

FEATURES

●

Switchable

320000 pixels CCD

●

Switchable between NTSC

(CCIR)

●

Internal electronic shutter :

Shutter speed is selectable from 1/W, 1/125,

1/250, 1/500, 1/1 000, 1/2 000, 1/4 000 and 1/10 000 s, in addition to this, 1/100 s (PAL : 1/120 s) in Flicker-less mode using parallel or serial code. Shutter speed can also be controlled in 1 H period using an external trigger to the EXST input.
