Features

ring leading dummy bits or multiple address bits in the serial data stream. In addition, BitGrabber Plus peripherals may be cascaded with existing BitGrabber™ peripherals. Because this device is a dual synthesizer, a single steering bit is used in the serial data stream to direct the data to either side of the chip. The phase/frequency detectors have linear transfer functions (no dead zones). The current delivered by the current source/sink outputs is controllable via the serial port. Also featured are low
  –power standby for either one or both loops and on
  –board support of an external crystal. .
