U2305B
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.
