MOTOROLA RF/IF DEVICE DATA
The new MC145170–2 is pin–for–pin compatible with the MC145170–1. A
comparison of the two parts is shown in the table below. The MC145170–2 is
recommended for new designs and has a more robust power–on reset
(POR) circuit that is more responsive to momentary power supply
interruptions. The two devices are actually the same chip with mask options
for the POR circuit. The more robust POR circuit draws approximately 20
μ
A
additional supply current. Note that the maximum specification of 100
μ
A
quiescent supply current has not changed.
The MC145170–2 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 accessof 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 reference
output, and both single– and double–ended 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–load feature is included. 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 counting down together.
The phase detectors are also initialized during the jam load.
