The MC145202–1 is pin–for–pin compatible with the previous generation
MC145200, MC145201, and MC145202. Table 1 highlights the different
features in these four devices. The MC145202–1 is recommended for new
designs, and also offers 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.

Slew–rate control is provided by a special driver designed for the 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.

(TSSOP–20)
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.
