... Atmel ’s silicon-germanium BiCMOS process (SiGMOS). The ATR2732N1 carries out all functions of RF and IF processing, as well as the clock-signal generation for these functions. Therefore, there is an integrated fractional PLL, which, equivalent to most of the other functions, can be controlled via an external digital bus. The RF functions include LNA, down-conversion mixing, amplifying, detec- tion, and gain control ...

... Functional Description The ATR2732N1 front-end IC was developed as a tuner IC for DAB reception. It was designed for operation in L-band (1452 MHz to 1492 MHz) and VHF BIII (167 MHz to 240 MHz). The front end contains gain-controlled LNAs, an L-band mixer with a corresponding PLL, and a VHF-band mixer with a fractional PLL ...

... Figure 3-1. 3.2 AGC in General There are three AGCs in the ATR2732N1, one for the RF signals (around the LNAs) (1) and (3), one for the very beginning of the IF path (mainly VHF mixer), and one for the IF amplifiers (5) down to the output to baseband (7). In these AGCs, the output signals of the relevant blocks are amplified, weakly band-pass fil- tered, rectified, and, finally, low-pass filtered ...

... RSSI Measurement The ATR2732N1 offers the option of getting information about the field strength. This is not an absolute real-field-strength value, but an indication of in which range the field strength is avail- able. This information can be obtained from the 8 low bits of the status register. ...

... IF frequency of 38.912 MHz for VHF or converted L-band signal is done by an additional on-chip VCO using an internal fractional-N PLL. Due to the digital tuning option of the reference frequency, the ATR2732N1 is able to support the single reference clock design if the baseband can support such a feature (as the ATR2740 does) ...
