VHF/UHF Tuner-IC
U2320B
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
D Frequency range from 48 to 860 MHz
D Band A: balanced high impedance mixer input and
amplitude controlled oscillator
D Band B: balanced low impedance mixer input and
symmetrical oscillator
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
