The new MC1451702 is pinforpin compatible with the MC1451701. A
comparison of the two parts is shown in the table below. The MC1451702 is
recommended for new designs and has a more robust poweron 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 µA
additional supply current. Note that the maximum specification of 100 µA
quiescent supply current has not changed. The MC1451702 is a singlechip 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 byteoriented 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 2byte serial transfer to the 16bit N register.
The device features fully programmable R and N counters, an amplifier at
the fin pin, onchip support of an external crystal, a programmable reference
output, and both single and doubleended phase detectors with lineartransfer 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 jamload feature is included. Whenever
a new divide ratio is loaded into the N register, both the N and R counters are
jamloaded with their respective values and begin counting down together.
The phase detectors are also initialized during the jam load. Operating Voltage Range: 2.7 to 5.5 V Maximum Operating Frequency:
185 MHz @ Vin = 500 mVpp, 4.5 V Minimum Supply
100 MHz @ Vin = 500 mVpp, 3.0 V Minimum Supply Operating Supply Current:
0.6 mA @ 3.0 V, 30 MHz
1.5 mA @ 3.0 V, 100 MHz
3.0 mA @ 5.0 V, 50 MHz
5.8 mA @ 5.0 V, 185 MHz Operating Temperature Range: 40 to 85°C R Counter Division Range: 1 and 5 to 32,767 N Counter Division Range: 40 to 65,535 Direct Interface to Motorola SPI Serial Data Port See Application Notes AN1207/D and AN1671/D See web site motsps.com for MC145170 control software.
