CXA3025N

CXA3025N All Band TV Tuner IC (VHF-CATV-UHF) Description The CXA3025N is a single chip TV tuner IC which performs as a mixer, oscillator for UHF and VHFCATV bands. An IF amplifier is also provided. This IC adopts a 24-pin SSOP package (0.8mm pitch) in response to the trend towards miniaturizing the tuner and automatic IC mounting. Features Low noise figure Superior cross modulation Low spurious Stable oscillating characteristics Local oscillator output for PLL Double tune filter connectable to MIX output Low thermal resistance package Structure Bipolar silicon monolithic IC Applications TV tuner CATV tuner VCR tuner Block Diagram and Pin Configuration (Top View) BANDSW UOSCB2 UOSCE2 UOSCE1 PLLOUT UOSCB1 VOSCC GND NC VOSCB IFOUT GND 24 pin SSOP (Plastic) Absolute Maximum Ratings (Ta = 25°C) 10.5 V Supply voltage VCC Storage temperature Tstg –65 to +150 °C Allowable power dissipation PD 1200 mW (when mounted on a board) Operating Conditions Supply voltage Operating temperature VCC Topr 9.0 ± 0.9 –20 to +75 V °C 24 23 22 21 20 19 18 17 16 15 14 13 OSC BUFF BAND SW UHF OSC VHF OSC IF AMP REG VHF MIX UHF MIX 1 2 3 4 5 6 7 8 9 10 11 12 IFIN2 GND MIXOUT2 MIXOUT1 Sony reserves the right to change products and specifications without prior notice.
