Abstract: An integrated circuit includes a tuner, a digital television (DTV) demodulator, an analog television (ATV) demodulator, and a controller. The tuner includes an input for receiving a radio frequency (RF) signal including at least one of an analog television signal and digital television signal, and including a first output terminal and a second output terminal. The DTV demodulator includes a DTV input coupled to the first output terminal of the tuner and includes a DTV output terminal. The ATV demodulator includes an ATV input coupled to the second output terminal of the tuner and includes an ATV output terminal. The controller is coupled to the tuner, the DTV demodulator, and the ATV demodulator to configure the tuner and at least one of the DTV demodulator and the ATV demodulator for receiving television content in a selected television format.

Abstract: A transceiver includes a processor, which is adapted to in a transmit mode of the transceiver, form at least part of a transmitter and in a receive mode of the transceiver, form at least part of a receiver. The transceiver may include at least one analog-to-digital converter to provide digital signals to the processor in both the transmit and receive modes of operation; and the transceiver may include at least one digital-to-analog converter to receive digital signals from the processor in the transmit and receive modes of operation. The processor may be fabricated on an integrated circuit with at least one of the analog-to-digital converters and/or with at least one of the digital-to-analog converters.

Abstract: In one embodiment, a set of tracking filters to be coupled between an amplifier and a mixer is provided. The tracking filters may be differently configured depending on band of operation. For example, a first set of the filters can be configured to maintain a substantially constant Q value across their operating bandwidth while a second set of the filters can be configured to maintain a substantially constant bandwidth across their operating bandwidth.

Abstract: A transceiver includes a processor and an analog-to-digital converter. The processor is adapted to in a transmit mode of the transceiver, generate a modulated signal in response to a first digital signal. In a receive mode of the transceiver, the processor is adapted to generate a demodulated signal in response to a second digital signal. The analog-to-digital converter provides the first digital signal in the transmit mode and provides the second digital signal in the receive mode.

Abstract: A radio receiver such as a frequency modulation (FM) receiver, for example, includes a radio frequency (RF) amplifier having an adjustable gain output. The RF amplifier may be configured to receive and amplify an incoming RF signal. The receiver also includes an intermediate frequency (IF) amplifier having an adjustable gain output. The IF amplifier may be configured to receive and amplify an IF signal that corresponds to the RF signal. The receiver also includes a gain control unit that is coupled to the RF amplifier and the IF amplifier. The gain control unit may be configured to independently adjust the gain of each of the RF amplifier and the IF amplifier, dependent upon a peak output level of both the RF amplifier and the IF amplifier.
