The MC145192 is a low–voltage single–package synthesizer with serial
interface capable of direct usage up to 1.1 GHz. A special architecture makes
this PLL very easy to program because a byte–oriented format is utilized. Due
to the patented BitGrabber
registers, no address/steering bits are required for
randomaccess of 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.
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.
The MC145192 phase/frequency detector B
φ
R and
φ
V outputs can be
powered from 2.7 to 5.5 V. This is optimized for 3.0 V systems. The
phase/frequency detector A PDout output must be powered from 4.5 to 5.5 V,
and is optimized for a 5 volt supply.
This 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 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.
