port which is SPI compatible. The serial port is byte-oriented to facilitate
control via an MCU. Due to the innovative BitGrabber Plus
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
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.

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.
