PLL Frequency Synthesizer with Serial Interface;

Introduction\nThe new MC145170-2 is pin-for-pin compatible with the MC145170-1. A comparison of the two parts is shown in Table 1 on page 2. The MC145170-2 is recommended for new designs and has a more robust power-on reset (POR) circuit that is moreresponsive 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.Operating Voltage Range: 2.7 to 5.5 V\nMaximum Operating Frequency:\n  185 MHz @ Vin= 500 mVpp, 4.5 V Minimum Supply\n  100 MHz @ Vin= 500 mVpp, 3.0 V Minimum Supply\nOperating Supply Current:\n  0.6 mA @ 3.0 V, 30 MHz\n  1.5 mA @ 3.0 V, 100 MHz\n  3.0 mA @ 5.0 V, 50 MHz\n  5.8 mA @ 5.0 V, 185 MHz\nOperating Temperature Range: -40 to 85°C\nR Counter Division Range: 1 and 5 to 32,767\nN Counter Division Range: 40 to 65,535\nPrograms through Standard Serial Peripheral Interface (SPI)\nSee Application Notes AN1207/D and AN1671/D\nContact Freescale for MC145170 control software.
