2.0 GHz PLL Frequency Synthesizers

Include On–Board 64/65 Prescalers

The MC145200 and MC145201 are single–package synthesizers with serial interfaces capable of direct usage up to 2.0 GHz. A special architecture makes these PLLs very easy to program because a byte–oriented format is utilized. 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 3–byte serial transfer to the 24–bit A register. The interface is both SPI and MICROWIRE? compatible.

The double–buffered R register allows new divide ratios to be presented to the three counters (R, A, and N) simultaneously.

? Maximum Operating Frequency: 2000 MHz @ Vin = 200 mV p–p

? Operating Supply Current: 12 mA Nominal

? Operating Supply Voltage Range (VDD and VCC Pins): 4.5 to 5.5 V

? Operating Supply Voltage Range of Phase Detectors (VPD Pin) —

MC145200: 8.0 to 9.5 V

MC145201: 4.5 to 5.5 V

? Current Source/Sink Phase Detector Output Capability: 2 mA Maximum

? Gain of Current Source/Sink Phase/Frequency Detector Controllable via Serial Port

? Operating Temperature Range: – 40 to +85°C

? R Counter Division Range: (1 and) 5 to 8191

? Dual–Modulus Capability Provides Total Division up to 262,143

? High–Speed Serial Interface: 4 Mbps

? OUTPUT A Pin, When Configured as Data Out, Permits Cascading of Devices

? Two General–Purpose Digital Outputs — OUTPUT A: Totem–Pole (Push–Pull) OUTPUT B: Open–Drain

? Power–Saving Standby Feature with Orderly Recovery for Minimizing Lock Times, Standby Current: 30 μA

? Evaluation Kit Available (Part Numbers MC145200EVK and MC145201EVK)

? See Application Note AN1253/D for Low–Pass Filter Design, and AN1277/D for Offset Reference PLLs for Fine Resolution or Fast Hopping
