Description

IFLB

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.
