2 / 32 page MC145170-2 Technical Data, Rev. 5 2 Freescale Semiconductor Introduction 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: 2.7 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 • Programs through Standard Serial Peripheral Interface (SPI) • See Application Notes AN1207/D and AN1671/D • Contact Freescale for MC145170 control software.
