1.1 GHz PLL Frequency Synthesizers
MC145190 MC145191
Include OnBoard 64/65 Prescalers
The MC145190 and MC145191 are singlepackage synthesizers with serial interfaces capable of direct usage up to 1.1 GHz. A special architecture makes these PLLs very easy to program because a byteoriented format is utilized. Due to the patented BitGrabberTM registers, no address/steering bits are r e q u i r e d for random access of the three registers. Thus, tuning can be accomplished via a 3byte serial transfer to the 24bit A register. The interface is both SPI and MICROWIRETM compatible. Each device features a singleended current source/sink phase detector output and a doubleended phase detector output. Both phase detectors have l i n e a r transfer functions (no dead zones). The maximum current of the singleended phase detector output is determined by an external resistor tied from the Rx pin to ground. This current can be varied via the serial port. The MC145190 features logiclevel converters and highvoltage phase/ f r e q u e n c y detectors; the detector supply may range up to 9.5 V. The M C 1 4 5 1 9 1 has lowervoltage phase/frequency detectors optimized for singlesupply systems of 5 V ± 10%. Each part includes a differential RF input which may be operated in a singleended mode. Also featured are onboard support of an external crystal and a programmable reference output. The R, A, and N counters are fully programmable. The C register (configuration register) allows the parts to be configured to meet various applications. A patented feature allows the C register to shut off unused outputs, thereby minimizing system noise and interference. In order to have consistent lock times and prevent erroneous data from being loaded into the counters, onboard circuitry synchronizes the update of the A register if the A or N counters are loading. Similarly, an update of the R register is synchronized if the R counter is loading. The doublebuffered R register allows new divide ratios to be presented to the three counters (R, A, and N) simultaneously. · Maximum Operating Frequency: 1100 MHz @ Vin = 200 mV pp · Operating Supply Current: 7 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) -- MC145190: 8.0 to 9.5 V MC145191: 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 · DualModulus Capability Provides Total Division up to 262,143 · HighSpeed Serial Interface: 4 Mbps · OUTPUT A Pin, When Configured as Data Out, Permits Cascading of Devices · Two GeneralPurpose Digital Outputs -- OUTPUT A: TotemPole (PushPull) OUTPUT B: OpenDrain · Patented PowerSaving Standby Feature with Orderly Recovery for Minimizing Lock Times, Standby Current: 30 µA · Evaluation Kit Available (Part Numbers MC145190EVK and MC145191EVK) · See Application Note AN1253/D for LowPass Filter Design, and AN1277/D for Offset Reference PLLs for Fine Resolution or Fast Hopping
