TUA 4401K
Wireless Components
Specification, 17.02.00
2.1 General Description
The TUA 4401K 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 comparison to two separate
IC’s 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 back-
ground receivers, capable for all world standards.
TUA 4401K 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. Double frequency operation possible
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
IF amplification, demodulation and STS
Low noise IF amplifier
Gain adjust with DC control voltage or serial bus possible
7 stage IF limiter with extended fieldstrength range suitable for the IF fre-
quency range of 10.7 MHz ... 21.4 MHz
Fieldstrength DC output and ADC output available
Low distortion coincidence demodulator (using short loop AFC principle)
with MPX output
Wideband multipath detector with analog output and ADC output
IF counter for search tuning stop with selectable IF center frequency,
window width and programmable thresholds for fieldstrength and multipath
evaluation
STS informations -in window-,-below-,-beyond- available
