HD49335HF

www.DataSheet4U.com HD49335F/HF CDS/PGA & 10-bit A/D TG Converter REJ03F0100-0100Z Rev.1.0 Feb.25.2004 Description The HD49335F/HF is a CMOS IC that provides CDS-PGA analog processing (CDS/PGA) suitable for CCD camera digital signal processing systems together with a 10-bit A/D converter and timing generator in a single chip. There are address map and timing generator charts besides this specification. May be contacted to our sales department if examining the details. Functions Correlated double sampling PGA Serial interface control 10-bit ADC Timing generator Operates using only the 3 V voltage Corresponds to switching mode of power dissipation and operating frequency Power dissipation: 220 mW (Typ), maximum frequency: 36 MHz (HD49335HF) Power dissipation: 150 mW (Typ), maximum frequency: 25 MHz (HD49335F) ADC direct input mode QFP 64-pin package Features Suppresses low-frequency noise, which output from CCD by the correlated double sampling. The S/H response frequency characteristics for the reference level can be adjusted using values of external parts and registers. High sensitivity is achieved due to the high S/N ratio and a wide dynamic range provided by a PG amplifier. PGA, pulse timing, standby mode, etc., is achieved via a serial interface. High precision is provided by a 10-bit-resolution A/D converter. Difference encoded gray code can be selected as an A/D output code. It is effective in suppression of solarization (wave pattern). ...
