U2309B - VHF/ UHF-Tuner-IC

General Description

This tuner IC requires a power supply of 9 V and performs the function of three separate oscillators an mixers, SAWF-driver, L.O.-output and tri-state band switch.

Additional to TV-tuner application this IC is usable for DAB (Digital Audio Broadcast) tuners.

Key Features
