U2309B
Overview
This tuner IC requires a power supply of 9 V and performs the function of three separate oscillators an mixers, SAWF-driver, L.O.-output and tri-state band switch. Additional to TV-tuner application this IC is usable for DAB (Digital Audio Broadcast) tuners.
- 9 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.
