1 / 27 page MC145170–1 MOTOROLA 1 Advance Information PLL Frequency Synthesizer with Serial Interface CMOS The 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 COMPARISION OF THE PLL FREQUENCY SYNTHESIZERS Parameter MC145170–1 MC145170 Technology 1.2 µm CMOS 1.5 µm CMOS Maximum Frequency with 5 V ± 10% Supply, fin 185 MHz 160 MHz Maximum Frequency with 5 V ± 10% Supply, OSCin 25 MHz 20 MHz Maximum Supply Voltage 5.5 V 6.0 V Maximum Input Capacitance, fin 7 pF 5 pF This document contains information on a new product.
