VHF/UHF Tuner-IC
Description
This tuner IC requires a power supply of 12 V and
performs the function of two separate oscillators and
mixers, SAW-filter driver and dual state band switch.
Features
Frequency range from 48 to 860 MHz
Band A: balanced high impedance mixer input and
amplitude controlled oscillator
Band B: balanced low impedance mixer input and
symmetrical oscillator
SAW filter driver with low impedance output
Voltage regulator for stable operating characteristics
ESD protection on all pins except oscillator pins and
RF-inputs
