Include On–Board 64/65 Prescalers
The MC145190 and MC145191 are single–package synthesizers with serial
interfaces capable of direct usage up to 1.1 GHz. A special architecture makes
these PLLs very easy to program because a byte–oriented format is utilized.
Due to the patented BitGrabber
registers, no address/steering bits are
required for randomaccessof the three registers. Thus, tuning can be
accomplished via a 3–byte serial transfer to the 24–bit A register. The interface
is both SPI and MICROWIRE
compatible.
Each device features a single–ended current source/sink phase detector
output and a double–ended phase detector 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.
The MC145190 features logic–level converters and high–voltage phase/
frequency detectors; the detector supply may range up to 9.5 V. The
MC145191 has lower–voltage phase/frequency detectors optimized for
single–supply systems of 5 V
±
10%.
Each part includes a differential RF input which 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 parts 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.
