The MC145193 is recommended for new designs and offers reduced  
power consumption. 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  
MC145193 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.

TECHNICAL DATA  
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.  
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.
