    摘要: A flexible asymmetrical digital subscriber line (ADSL) transmitter is able to operate simultaneously with integrated services digital network (ISDN) terminal equipment (TE) using a common telephone line (18). The ADSL transmitter changes the frequency content of a frequency-encoded ADSL signal (104) so that its frequency content does not overlap the frequency content of the ISDN TE signal. A corresponding ADSL receiver located within a central office (CO) adapts to the changed frequency content, allowing the ADSL signal to be transmitted over the telephone line without substantial loss of signal integrity. In one embodiment, an ADSL transmitter (100) converts ADSL symbols making up the frequency-encoded ADSL signal (104) into a corresponding time domain signal. The transmitter (100) then interpolates the time domain signal and high pass filters the interpolated signal. This high pass filtered signal is then converted to analog form, bandpass filtered, and driven onto the telephone line (18).

    摘要: Systems and methods for controlling operation of an integrated circuit by applying below ground voltage to one or more pins of the integrated circuit, and in which the application of a below ground pin voltage may be employed as an initiator of (or condition for) a given mode of circuit operation in a manner that prevents the inadvertent initiation of the given mode of operation that may otherwise occur due to accidental application of an above ground voltage to one or more pins of the integrated circuit.

    摘要: A method for mitigating interference from a switched-mode power supply begins by comparing a channel of interest of a plurality of channels with a switching rate of a switch-mode power supply. The method continues when the channel of interest compares unfavorably to the switching rate by adjusting the switching rate of the switch-mode power supply until the channel of interest compares favorably to the switching rate.

A digital clock generator generates a first in-phase digital clock signal having a plurality of first in-phase digital clock cycles over a predetermined period and a first quadrature phase digital clock signal having a plurality of first quadrature phase digital clock cycles over the predetermined period. The plurality of first in-phase digital clock cycles are substantially interleaved with the plurality of first quadrature phase digital clock cycles over the predetermined period.
