Peripheral device receiver detection in a high noise environment |
摘要 |
A peripheral device includes a data port having high and low impedance terminations, a transmitter having a data signal generator and a receiver detector. The data signal generator is electrically coupled to the low impedance termination of the data port when in a low impedance operating mode, and to the high impedance termination when in a high impedance operating mode. The receiver detector includes a noise detector adapted to detect a presence or an absence of rail-to-rail noise at the data port when the transmitter is in the high impedance operating mode.
