FREQUENCY TRANSLATION MODULE PROTECTION CIRCUIT |
摘要 |
<p>An architecture for protecting circuitry used for signal communications between a frequency translation module (20) and a decoder (60) from transient voltage surges. According to an exemplary embodiment, the apparatus comprises a first signal path between a transmission line and a first reference potential for conducting negative voltage surges between said transmission line and said first reference potential, comprising a first diode and a first clamping diode, wherein a second reference potential is coupled to a junction of the first diode and the first clamping diode, and a second signal path between the transmission line and the first reference potential, comprising a second diode and a second clamping diode for conducting positive voltage surges between said transmission line and said first reference potential, wherein a second reference potential is coupled to a junction of the second diode and the second clamping diode.</p> |
