Packet data receiver with sampled data output and background light cancellation.

摘要

A digital burst-mode packet data receiver receives (by PD1) high-speed burst-mode packet data signals superimposed on a lower frequency data signal. The receiver includes a first detector (PEAK DETECTOR) for detecting the received high-speed burst-mode packet data which is reset (by RESET) during the time period between consecutive bursts of the high-speed packet data signal. A second detector (SHI) detects the lower frequency data signal during a predetermined portion of the time period between consecutive bursts of the high-speed packet data.
