Overview
The LA1844, LA1844M is designed for use in mini systems and is a single-chip tuner IC that provides electronic tuning functions using SD/IF-count technique. It incorporates a pilot canceler and an adjustment-free MUX VCO circuit, thus allows additional parts to be reduced.
Features
⢠Integrated MPX VCO (ceramic resonators are no longer required.)
⢠Built-in adjacent channel interference rejection function (114kHz, 190kHz)
⢠Supports both SD and IF-count techniques
⢠Both FM SD sensitivity and bandwidth can be set
⢠Pilot canceler built in.
⢠Package : DIP24S(300mil) [LA1844], MFP24S(300mil) [LA1844M]
