MC145201 Overview
Key Features
- a single–ended current source/sink phase detector output and a double–ended phase detector 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
- The MC145200 features logic–level converters and high–voltage phase/ frequency detectors; the detector supply may range up to 9.5 V
- The MC145201 has lower–voltage phase/frequency detectors optimized for single–supply systems of 5 V ± 10%
- Each part includes a differential RF input which may be operated in a single–ended mode
- Also featured are on–board support of an external crystal and a programmable reference output
- The R, A, and N counters are fully programmable
- The C register (configuration register) allows the parts to be configured to meet various applications
