Clock signal synthesizer for ultra-wideband (UWB) transmitter or transceiver applications

A method, comprising:

• generating a clock signal;
• generating first, second, and third clock signals based on the clock signal;
• generating a transmit baseband digital signal based on the first clock signal;
• generating an ultra-wideband (UWB) pulse signal based on the transmit baseband digital signal and the second clock signal;
• and
• generating a transmit radio frequency (RF) signal based on the UWB pulse signal and the third clock signal.

An apparatus, comprising:

• means for generating a clock signal;
• means for generating first, second, and third clock signals based on the clock signal;
• means for generating a transmit baseband digital signal based on the first clock signal;
• means for generating an ultra-wideband (UWB) pulse signal based on the transmit baseband digital signal and the second clock signal;
• and
• means for generating a transmit radio frequency (RF) signal based on the UWB pulse signal and the third clock signal.

An apparatus, comprising:

• an oscillator configured to generate a clock signal;
• a first frequency divider configured to frequency divide the clock signal by a first divider ratio to generate a local oscillator (LO) clock signal;
• a second frequency divider configured to frequency divide the clock signal or the LO clock signal by a programmable second divider ratio to generate a first oversampling clock signal;
• a third frequency divider configured to frequency divide the first oversampling clock signal by a third divider ratio to generate a baseband clock signal;
• and
• a fourth frequency divider configured to frequency divide the LO clock signal by a fourth divider ratio to generate a second oversampling clock signal.
