HIGH-PERFORMANCE CONVERSION BETWEEN SINGLE-ENDED AND DIFFERENTIAL/COMMON-MODE SIGNALS

摘要

A signal conversion apparatus (40, 50) includes first and second input ports (4 IA and 41B, 51B and 51A) and first and second output ports (41C and 41D, 52A and 52B). A first splitter (44) is coupled to convert a first single-ended signal received on the first input port into a differential signal including first and second opposite-phase components, and to provide the first and second opposite-phase components respectively on the first and second output ports. A second splitter (48) is separate from the first splitter and is coupled to convert a second single-ended signal received on the second input port into a common-mode signal including first and second in-phase components, and to provide the first and second in-phase components respectively on the first and second output ports together with the first and second opposite-phase components.
