LR38585
Single-chip Driver IC for 270 k/320 k-pixel
B/W CCDs with Dual-power-supply Operation
DESCRIPTION
The LR38585 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 1/3-type 270 k/320 k-pixel B/W CCD
area sensors with a dual-power-supply operation
• Switchable between EIA and CCIR modes
www.DataS•heEelet4cUtr.ocnoimc shutter and EE control are possible
• Maximum shutter speed is selectable from
approx. 1/100 000 s, 1/50 000 s and 1/30 000 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 V power supplies
• Package :
48-pin QFP (P-QFP048-0707) 0.5 mm pin-pitch

output
DESCRIPTION
An output pin of phase comparator. The pulse is
generated by comparing the phase of the inner VSYNC
pulse with mono-multivibrator output which is made from
the falling edge of LLIN (pin 13) adjusted by mono-multi-
vibrator or with the falling edge of VD2I (pin 14).
