U2300B
VHF/ UHF-Tuner-IC
Description
This tuner IC requires a power supply of 12 V and per-
forms 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.
Features
D Frequency range from 48 to 860 MHz
D Band A: balanced high impedance mixer input and
amplitude controlled oscillator
D Band B + C: balanced low impedance mixer input and
symmetrical oscillator
D Balanced L.O.-output for prescalers or PLL
D SAW filter driver with low impedance output
D Voltage regulator for stable operating characteristics
D ESD protection on all pins except oscillator pins and
RF-inputs
Benefits
D The integration of 3 bands allows to design economi-
cal 3-band tuners
