LANSDALE
The Lansdale ML145170 is a single–chip synthesizer capable of direct
usage in the MF, HF and VHF bands. A special architecture makes this
PLL easy to program. Either a bit– or byte–oriented format may be used.
Due to the patented BitGrabber™ registers, no address/steering bits are
required for random access of the three registers. Thus, tuning can be
accomplished via a 2–byte serial transfer to the 16-bit N register.
The device features fully programmable R and N counters, an amplifier
at the fin pin, on–chip support of an external crystal, a programmable ref-
linear transfer functions (no dead zones). A configuration (C) register
allows the part to be configured to meet various applications. A patented
feature allows the C register to shut off unused outputs, thereby minimiz-
ing noise and interference.
In order to reduce lock times and prevent erroneous data from being
Whenever a new divide ratio is loaded into the N register, both the N and
R counters are jam–loaded with their respective values and begin count-
ing down together. The phase detectors are also initialized during the jam
load.
