Product Information

CXD1267AN CCD Vertical Clock Driver Description The CXD1267AN is a vertical clock driver for CCD image sensors. This IC is the successor of the CXD1250N with attractive features. Power consumption is reduced approximately 30% for the CXD1267AN version. Features 1) Substrate voltage (Vsub) generator is built-in. • Variable Vsub in the range of 4.0V to 18.5V. • Reduction of peripheral parts saves space. 2) Only two power supplies (+15V and –8.5V) are needed. 3) 3.3V clock interface is acceptable. 4) 20-pin SSOP package is used. 5) Low power consumption 90mW (CXD1267N) 62mW (CXD1267AN) approximately 30% reduction 20 pin SSOP (Plastic) Appllications CCD cameras Structure CMOS Absolute Maximum Ratings (Ta = 25°C) VL • Supply voltage 0 to –10 • Supply voltage VH VL – 0.3 to 2VL + 35 • Supply voltage VM VL – 0.3 to 3.0 • Input voltage VI VL – 0.3 to VH + 0.3 • Output voltage (V2, V4) MVφ VL – 0.3 to VM + 0.3 • Output voltage (V1, V3) HVφ VL – 0.3 to VH + 0.3 • Output voltage (VSHT) HHVφ VL – 0.3 to VH + 0.3 • Operational amplifier output current IDCOUT ±5 • Operating temperature Topr –25 to +85 • Storage temperature Tstg –40 to +125 Recommended Operating Conditions • Supply voltage VH • Supply voltage VM • Supply voltage VL • Input voltage (except for pin 3) VI • Operational amplifier input voltage VIOP • Operating temperature Topr V V V V V V V mA °C °C 14.5 to 15.5 0 –6.0 to –9.0 0 to 6.0 1.0 to 4.5 –20 to +75 V V V V V °C Sony reserves the right to change products and specifications without prior notice.
