20130077662 | SYSTEMS AND METHODS FOR DIGITAL INTERFACE TRANSLATION - Systems and methods of digital interface translation are described. One embodiment of the invention includes multiple receiver lanes, where at least one of the receiver lanes is configured to receive a data channel at a first data rate and encoded in accordance with an input digital interface standard, an auxiliary channel input configured to receive an auxiliary data channel, and a single transmitter lane configured to output a single data channel at a second data rate and encoded in accordance with an output digital interface standard. In addition, the multilane to single lane digital interface translator is configured to decode the received data into data streams, and interleave the data streams to form packets, the multilane to single lane digital interface translator is configured to insert auxiliary data received via the auxiliary channel input and idle data between the packets to produce an output data stream that is rate matched to the second data rate, and the multilane to single lane digital interface translator is configured to encode the output data stream in accordance with the output digital interface standard. | 03-28-2013 |

One embodiment includes a system configured to select at least one content channel from an input signal including a plurality of content channels modulated onto a carrier, the system including: a digital channelizer switch including: a high speed analog to digital converter configured to digitize an intermediate frequency signal; a digital channelizer configured to digitally tune a content channel from the digitized intermediate frequency signal; and a high speed digital to analog converter configured to generate an analog output signal using the content channel digitally tuned from the digitized intermediate frequency signal by the digital channelizer. | 07-26-2012 |
20100060496 | MINIMIZING ADVERSE EFFECTS OF SKEW BETWEEN TWO ANALOG-TO-DIGITAL CONVERTERS - Skew between a first clock signal received by a first analog-to-digital converter (ADC) and a second clock signal received by a second ADC is adjusted to minimize error. Each ADC has an ADC element that produces a respective first or second digital output signal in response to an analog input signal and a respective first or second clock signal. A correction signal is produced in response to the first and second digital output signals. The skew between the first and second clock signals is then adjusted in response to the correction signal. | 03-11-2010 |
20100033359 | NONLINEAR COMPENSATION IN ANALOG TO DIGITAL CONVERTERS - An apparatus for converting an analog signal to a digital signal comprising a first analog to digital converter for generating a first digital value from an analog value. A second analog to digital converter for generating a second digital value from the analog value. Logic for determining a correction factor for the second digital value based on a difference between the first digital value and the second digital value, wherein the logic updates the correction factor. | 02-11-2010 |
