CXD2300Q

CXD2300Q 8-bit 18MSPS Video A/D Converter with 3.3V Power Supply Operation Function Description The CXD2300Q is an 8-bit CMOS A/D converter for video with synchronizing clamp function and can operate on 3.3 V power supply. The adoption of 2 step-parallel method achieves ultra-low power consumption and a maximum conversion speed of 18MSPS. Features Resolution: 8-bit ± 1/2LSB (DL) Maximum sampling frequency: 18MSPS Low power consumption: 18 mW (at 18MSPS typ.) (reference current excluded) Synchronizing clamp function Clamp ON/OFF function Reference voltage self-bias circuit Input CMOS compatible 3-state TTL compatible output Single 3.3 V power supply Low input capacitance: 8 pF Reference impedance: 330 Ω (typ.) 32 pin QFP (Plastic) Absolute Maximum Ratings (Ta=25 °C) Supply voltage VDD 7 Reference voltage VRT, VRB VDD + 0.5 to VSS – 0.5 Input voltage VIN VDD + 0.5 to VSS – 0.5 (Analog) Input voltage VI VDD + 0.5 to VSS – 0.5 (Digital) Output voltage VO (Digital) Storage temperature Tstg V V V V VDD + 0.5 to VSS – 0.5 V –55 to +150 °C Applications Wide range of applications that require high-speed A/D conversion such as TV and VCR.
