A special architecture makes this PLL easy to program. 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 ref- 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 minimiz- ing noise and interference. In order to reduce lock times and prevent erroneous data from being 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 count- ing down together. The phase detectors are also initialized during the jam load. • Operating Voltage Range: 2.7 to 5.5 V • Operating Temperature Range: TA = –40º to +85º C • 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 • 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 www.lansdale.com for ML145170 control software BitGrabber™ is a trademark of Motorola/Freescale erence output, and both single and double–ended phase detectors with loaded into the counters, a patented jam load feature is included.
