Quick Detail:

 

 Low-Voltage 2.0 GHz PLL Frequency Synthesizer Includes On-Board 64/65 Prescaler

 

 

Description:

 

The MC145202 is a low–voltage single–package synthesizer with serial interface capable of direct usage up to 2.0 GHz.

The counters are programmed via a synchronous serial port which is SPI compatible. The serial port is byte-oriented to facilitate control via an MCU. Due to the innovative BitGrabber Plus registers, the MC145202 may be cascaded with other peripherals featuring Bit Grabber Plus without requiring leading dummy bits or address bits in the serial data stream. In addition, Bit Grabber Plus peripherals may be cascaded with existing Bit Grabber peripherals.

The device features a single–ended current source/sink phase detector A output and a double–ended phase detector B output. Both phase detectors have linear transfer functions (no dead zones). The maximum current of the single–ended 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.

Slew–rate control is provided by a special driver designed for the REF out pin.

This minimizes interference caused by REF out. This part includes a differential RF input that may be operated in a single–ended mode. Also featured are on–board 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 part 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, on–board 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 double–buffered R register allows new divide ratios to be presented to the three counters (R, A, and N) simultaneously.
