摘要： A direct downconversion receiver architecture having a DC loop to remove DC offset from the signal components, a digital variable gain amplifier (DVGA) to provide a range of gains, an automatic gain control (AGC) loop to provide gain control for the DVGA and RF/analog circuitry, and a serial bus interface (SBI) unit to provide controls for the RF/analog circuitry via a serial bus. The DVGA may be advantageously designed and located as described herein. The operating mode of the VGA loop may be selected based on the operating mode of the DC loop, since these two loops interact with one another. The duration of time the DC loop is operated in an acquisition mode may be selected to be inversely proportional to the DC loop bandwidth in the acquisition mode. The controls for some or all of the RF/analog circuitry may be provided via the serial bus.

摘要： A shared real-time counter is configured to provide an accurate counter output based on a fast clock period when driven by a fast clock signal or by a slow clock signal. Combinational logic circuitry provides glitch free switching between a fast clock signal input to the counter and a slow clock input to the counter. The counter is always on and increases its count by an appropriate rational number of counts representing fast clock cycles for every cycle of the fast clock while in a fast clock mode, and by an appropriate rational number of fast clock periods for every cycle of the slow clock signal while in a slow clock mode.

摘要： In a particular embodiment, a single step increment calculation module is responsive to a first ramp control value and a second ramp control value. The single step increment calculation module generates a single step frequency adjustment as an output. The generated single step frequency adjustment is applied to a system clock signal having a first frequency to change the system clock signal to a second clock signal having a second frequency. The first frequency is different from the second frequency and the system clock signal has a first duty cycle that is within a tolerance range of a second duty cycle of the second clock signal.
