PLL FREQUENCY SYNTHESIZER WITH SERIAL INTERFACE
Advance Information! !" -
CMOSThe new MC145170–1 is pin–for–pin compatible with the MC145170. A
comparison of the two parts is shown in the table below. The MC145170–1 is
recommended for new designs.
The MC145170–1 is a single–chip 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– 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 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. Operating Voltage Range: 2.5 to 5.5 V Maximum Operating Frequency:
185 MHz @ Vin = 500 mV p–p, 4.5 V Minimum Supply
100 MHz @ Vin = 500 mV p–p, 3.0 V Minimum Supply Operating Supply Current: 0.6 mA @ 3 V, 30 MHz
1.5 mA @ 3 V, 100 MHz
3.0 mA @ 5 V, 50 MHz
5.8 mA @ 5 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 and National MICROWIRE Serial Data
Ports Chip Complexity: 4800 FETs or 1200 Equivalent Gates See Application Note AN1207/D
