Configurable I/O Chip Enables Bi-Directional Communication on Single BNC

摘要

National Semiconductor announced a configurable I/O chip for serial digital interface (SDI) broadcast video equipment. This I/O chip allows manufacturers to program their BNCrninterface connectors as either inputs (equalizer) or outputs (cable driver). The PowerWise LMH0387 targets 3C/HD/SD video capture and editing cards that have a limited number of coax BNC connectors, as well as processing and distribution equipment that support a wide variety of I/O configurations.
