摘要:
In one embodiment, an interface may include various mechanisms to handle incoming clock and data signals. More specifically, the interface includes a first multiplexer to receive a first data signal via a serial peripheral interface (SPI) bus coupled to a first pin and a second multiplexer to receive a first clock signal via the SPI bus coupled to a second pin of the first IC and a second clock signal via an inter-integrated circuit (I2C) bus coupled to a third pin. In addition, the interface may include a decoder to receive the second clock signal and a second data signal via the I2C bus coupled to a fourth pin.
摘要:
A multi-standard single-chip receiver for digital demodulation of TV signals broadcasted over any of multiple digital television means, e.g., satellite, cable and terrestrial, is provided. The receiver can receive and demodulate a variety of different signal types received from one or more up-front tuners. A demodulator architecture in accordance with an embodiment of the present invention can be optimized to re-use common demodulation processing blocks for the different incoming signal types.

摘要:
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.

摘要:
In the slaving process, a reference signal is sampled by a clock signal of an oscillator and then digitized. The value representative of a phase error is then deduced from the sampled and digitized signal. A correction value is then deduced from this phase error to correct a digital value representing the oscillator control voltage. The device of the invention allows this process to be implemented. The invention also relates to a voltage-controlled crystal oscillator incorporating such a device.
