LR38580
Single-chip Driver IC for 270 k/320 k-pixel
B/W CCDs with Dual-power-supply Operation
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
