No Preview Available ! CXA3125N All Band TV Tuner IC (VHF-CATV-UHF) For the availability of this product, please contact the sales office. Description The CXA3125N is a TV tuner IC which integrates 16 pin SSOP (Plastic) local oscillator and mixer circuits for VHF band, local oscillator and mixer circuits for UHF band, and an IF amplifier onto a single chip. This IC adopts a 16-pin SSOP package and is suitable for miniaturizing voltage synthesizer tuner. Features • Low noise figure • Superior cross modulation • Low power consumption (5 V, 43 mA typ.) • IF output can be selected from symmetrical or asymmetrical • SSOP 16-pin package Applications • TV tuners • VCR tuners • CATV tuners Absolute Maximum Ratings (Ta=25 °C) • Supply voltage VCC –0.3 to +5.5 V • Storage temperature Tstg –55 to +150 °C • Allowable power dissipation PD 625 mW (when mounted on a printed circuit board) Operating Conditions • Supply voltage • Operating temperature VCC Topr 4.75 to 5.30 –20 to +75 V °C Structure Bipolar silicon monolithic IC Sony reserves the right to change products and specifications without prior notice.
