CXA1665AM-S

CXA1665AM/AM-S All Band TV Tuner IC (VHF-CATV-UHF) Description The CXA1665AM/AM-S is a single chip TV tuner IC which performs as an oscillator, mixer for VHF/CATV and UHF bands. An IF amplifier is also provided. This IC adopts a 16-pin SOP package in response to the trend toward miniaturizing the tuner and automatic IC mounting. This IC achieves a large reduction of external parts in addition to miniaturizing the tuner and increasing manufacturing productivity, reliability and design efficiency. Features On-chip oscillator and mixer for UHF band Low noise figure Reduced spurious interference Superior cross modulation distortion Stable oscillating characteristics Absolute Maximum Ratings (Ta = 25°C) Supply voltage VCC 11 V Storage temperature Tstg –65 to +150 °C Allowable power dissipation PD 980 mW (When mounted on a board) 16 pin SOP (Plastic) Structure Bipolar silicon monolithic IC Applications CTV tuner CATV UP-DOWN converter FM detector for 2nd IF satellite broadcasts Operation Conditions Supply voltage Operating temperature VCC 9.0 ± 0.9 Topr –20 to +75 V °C Block Diagram and Pin Configuration (Top View) UOSC B2 UOSC E2 UOSC E1 VOSC C UOSC B1/SW UHF IN2 16 15 14 13 REG 12 11 10 SW UHF OSC UHF MIX VHF OSC – IF + AMP 1 2 3 4 5 V.
