MC145202F

Product Summary

The MC145202F 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 MC145202F 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.
