SI4136-F-GM

Clock Generator 2MHz to 50MHz Input 28Pin QFN EP

Description

The Si4136 is a monolithic integrated circuit that performs both IF and RF synthesis for wireless communications applications. The Si4136 includes three VCOs, loop filters, reference and VCO dividers, and phase detectors. Divider and powerdown settings are programmable through a three-wire serial interface.
