General Description:
The TUA 4401 is a carradio IC using BICMOS technology. The combination of
an analog FM receiver and a digital PLL synthesizer on the same chip reduces
the overall pin count in comparison of two separate ICs and in addition the
number of necessary external components. This gives the flexibility both for
high performance and low cost applications. The recommended applications for
this device are FM only carradios and background receivers, capable for all
world standards.
1. Frontend
Features:
strictly symmetrical RF sections
high level, high impedance mixer input with improved dynamic range
high input / output 3rd order interception point
balanced or unbalanced use of the mixer
