Type
TDA 4360X
1.2
The TDA 4360X is an integrated dual conversion AM receiver for use in car radios.
The input signal passes a linear mixer for conversion into the 1. IF (~ 10 MHz). Via an
external bandpass filter (CER filter, quartz filter) the 1. IF is converted in a second linear
mixer to the 2. IF (~ 460 kHz).
After an external narrowband selectivity (CER filter) the 2. IF passes an automatic gain
controlled (AGC) amplifier and is then demodulated to the AF. The AGC time constant
can be switched with a ratio of 20.
For counter controlled search tuning stop (STS) the frequencies of the 1. LO and the
2. IF are available.
