2.3 GHz to 76.5 MHz down-converter
High-performance single signal path for
satellite and terrestrial signals
Operation in the 2320 to 2345 MHz band
Low-power consumption, 3.3V operation
On-chip PLL with lock flag
Fractional synthesizer including integrated
VCO
Direct Xtal connection
High-Performance Linear RF/IF AGC
Low cost external components
IIC-bus slave control interface
The STA210N is assembled in a VFQFPN68
package. The front-end architecture is a down
converter (see
Figure 1),
with one RF down
conversion path, with an on chip image frequency
suppression, on chip AGC system, and one IF
variable gain path.
The IF output is usable for IF sampling
architecture.
The front-end processes both satellite and
terrestrial signals.
The IC is able to split the three Sirius broadcast
component signals into their respective sub-
bands via three different SAW filters. The
STA210N includes all the RF functions up to IF,
and it manages the signals going to and coming
from the base-band.
