40 to 85°C) Symbol VIL VIH VHys VOL VOH IOL IOL IOL IOL IOH IOH IOH Parameter Maximum Low Level Input Voltage (Din, CLK, ENB) Minimum High

Key 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 REFout pin. This minimizes interference caused by.

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145202/D MC145202 Low-Voltage 2.0 GHz PLL Frequency Synthesizer Includes On–Board 64/65 Prescaler 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 BitGrabber Plus without requiring leading dummy bits or address bits in the serial data stream. In addition, BitGrabber Plus peripherals may be cascaded with existing BitGrabber™ peripherals.
