Advance Information
PLL Frequency Synthesizer
with Serial Interface
CMOS
The new MC145170鈥? is pin鈥揻or鈥損in compatible with the MC145170. A
comparison of the two parts is shown in the table below. The MC145170鈥? is
recommended for new designs.
The MC145170鈥? is a single鈥揷hip synthesizer capable of direct usage in the
MF, HF, and VHF bands. A special architecture makes this PLL the easiest to
program in the industry. Either a bit鈥?or byte鈥搊riented format may be used. Due
to the patented BitGrabber鈩?registers, no address/steering bits are required for
random access
of the three registers. Thus, tuning can be accomplished via a
2鈥揵yte serial transfer to the 16鈥揵it N register.
The device features fully programmable R and N counters, an amplifier at the
fin pin, on鈥揷hip support of an external crystal, a programmable reference
output, and both single鈥?and double鈥揺nded phase detectors with 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 minimizing noise and interference.
In order to reduce lock times and prevent erroneous data from being loaded
into the counters, a patented jam鈥搇oad feature is included. Whenever a new
divide ratio is loaded into the N register, both the N and R counters are
jam鈥搇oaded with their respective values and begin counting down together. The
phase detectors are also initialized during the jam load.
