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.
Slew–rate control is provided by a special driver designed for the REFout pin.
This minimizes interference caused by REFout.
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.
