Patent ID: 7489177

Claim:
A wireless communication device having a transmitter that generates electromagnetic interference when operating in a transmit mode, the transmit mode being a mode during which the wireless communication device transmits data over a wireless network, comprising: a clock circuit including a first clock element configured to generate a first clock output, and a second clock element configured to generate a second clock output; and a controller configured to switch between the first clock output and the second clock output when the transmitter is operating in the transmit mode such that the second clock output is output from the clock circuit when the wireless communication device is operating in the transmit mode and the first clock output is output from the clock circuit when the wireless communication device is not operating in the transmit mode; wherein the first clock element is an analog clock element and the first clock output is an oscillating clock output; and wherein the second clock element is a digital clock element and the second clock output is a digital clock output.
