1.1 GHZ PLL FREQUENCY SYNTHESIZER

The MC145193 is recommended for new designs and offers reduced power consumption. 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 MC145193 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.

•Maximum Operating Frequency: 1100 MHz @ – 10 dBm
