CXA3185/3186N
All Band TV Tuner IC with On-chip PLL
Description The CXA3185/3186N is a monolithic TV tuner IC which integrates local oscillator and mixer circuits for VHF band, local oscillator and mixer circuits for UHF band, an IF amplifier and a tuning PLL onto a single chip, enabling further miniaturization of the tuner. Features • Low noise figure • Low power consumption (5 V, 54 mA typ.) • On-chip tuning PLL (3-wire bus format) • Selection of frequency steps 31.25 kHz, 50 kHz and 62.5 kHz • On-chip 4-output band switch Applications • TV tuners • VCR tuners • CATV tuners Structure Bipolar silicon monolithic IC 30 pin SSOP (Plastic)
Absolute Maximum Ratings (Ta = 25 °C) • Supply voltage VCC1,VCC2 –0.3 to +5.5 VCC3 –0.3 to +10.
