The TUA 4401 is the first Infineon Carradio IC using BICMOS technology.
The combination of an analog FM receiver circuit and a digital PLL synthesizer on the same chip reduces the
over all pin count in comparision to two separate IC’s and in addition the number of necessary external com-
ponents. 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.
General Description
TUA 4401 features:
Frontend
- High level, high impedance mixer input with improved dynamic range
- High input / output 3rd order intercept point
- Integrated prestage AGC generation and control for PIN diodes and MOS tetrode
- Bus controlled AGC threshold
- 2 pin 1st local oscillator with improved low phase noise, internally coupled to PLL
- Strictly symmetrical RF parts
- PLL with fast acquisition mode
- Resolution 100 kHz, 50 kHz, 25 kHz, 12,5 kHz, 10 kHz and 6.25 kHz
- High running (61.5 MHz) crystal oscillator to avoid interference with bus controlled adjustment
