  • Bit rate agile onboard telemetry formatter
    Patent number: 7228465
    Abstract: A bit rate Agile Onboard Telemetry formatting system addresses the increased demands on the efficiency of telemetry systems. The present invention thins and reorders data streams, adjusting bit rates of a PCM stream using a bit-locked loop to match the desired information rate exactly. The present invention accomplishes the adjustment through hardware by synthesizing a clock whose operating frequency is derived from the actual timing of the input format. Firmware manages initialization and error management.
