Includes On–Board 64/65 Prescaler

The MC145202 is a low–voltage single–package synthesizer with serial  
interface capable of direct usage up to 2.0 GHz.

The counters are programmed via a synchronous serial port which is SPI  
compatible. The serial port is byte-oriented to facilitate control via an MCU. Due  
to the innovative BitGrabber Plus registers, the MC145202 may be cascaded  
with other peripherals featuring BitGrabber Plus without requiring leading  
dummy bits or address bits in the serial data stream. In addition, BitGrabber  
Plus peripherals may be cascaded with existing BitGrabber peripherals.  
The device features a single–ended current source/sink phase detector A  
output and a double–ended phase detector B output. Both phase detectors  
have linear transfer functions (no dead zones). The maximum current of the  
single–ended phase detector output is determined by an external resistor tied  
from the Rx pin to ground. This current can be varied via the serial port.

This part includes a differential RF input that may be operated in a  
single–ended mode. Also featured are on–board support of an external crystal  
and a programmable reference output. The R, A, and N counters are fully  
programmable. The C register (configuration register) allows the part to be  
configured to meet various applications. A patented feature allows the C  
register to shut off unused outputs, thereby minimizing system noise and  
interference.

In order to have consistent lock times and prevent erroneous data from being  
loaded into the counters, on–board circuitry synchronizes the update of the A  
register if the A or N counters are loading. Similarly, an update of the R register  
is synchronized if the R counter is loading.  
The double–buffered R register allows new divide ratios to be presented to  
the three counters (R, A, and N) simultaneously.
