CXA3186N - 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.
