The MC145202–1 is recommended for new designs and has improved  
suppression of reference sideband spurs. 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 MC145202–1 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.

TECHNICAL DATA  
Slew–rate control is provided by a special driver designed for the REF  
out  
pin. This minimizes interference caused by REF  
.

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.
