DESCRIPTION

The LR38580 is a CMOS single-chip driver IC which

generates timing pulses for driving 270 k/320 k-

pixel B/W CCD area sensors with a dual-power-

supply operation, synchronous pulses for TV

signals and processing pulses for video signals.

FEATURES

• Designed for 270 k/320 k-pixel B/W CCD area

sensors with a dual-power-supply operation

• Switchable between EIA and CCIR modes

• Electronic shutter and EE control are possible

• Maximum shutter speed is selectable from

approx. 1/100 000 s, 1/56 000 s and 1/32 000 s

• Starting shutter speed is selectable from approx.

1/100 000 s and 1/1 000 s

• Flicker-less function

• Switchable between normal and mirror images

• External synchronization is possible

• Level shifter for readout and shutter pulses included

• Dual +5 V and +12.5 V power supplies

• Package :

48-pin QFP (QFP048-P-0707) 0.5 mm pin-pitch
