Overview

This tuner IC requires a power supply of 5 V and performs the function of three separate oscillators an mixers, SAWF-driver, L.O.-output and tri-state band switch. This tuner IC is decigned for high performance tuners for TV, VCR and PCs.

  • 5 V supply voltage
  • Frequency range from 48 to 860 MHz
  • Band A: balanced high impedance mixer input and amplitude controlled oscillator
  • Band B + C: balanced low impedance mixer input and symmetrical oscillator
  • Balanced L. O.-outputs for prescalers or PLL
  • SAW filter driver with low impedance output
  • Voltage regulator for stable operating characteristics
  • ESD protection on all pins except oscillator pins and RF-inputs Benefits
  • The integration of 3 bands and the small SSO28 package allows to design very small and economical 3-band tuners with high performance.
