U2300B
Overview
This tuner IC requires a power supply of 12 V and performs the function of three separate oscillators and mixers, SAWF-driver, L.O.-output and tri-state band switch. Applications are 12 V TV- and VCR-tuners.
- 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.-output 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 allows to design economical 3-band tuners
