Fairchild Semiconductor Announces Industry’s First High-Bandwidth Three-Input Video Switch for High-Definition Video Signals
San Jose, CA - Fairchild Semiconductor’s (NYSE: FCS) FSAV433 is the industry’s first high-bandwidth 3-port 3:1 video switch. The FSAV433 optimizes high-performance operation for LCD displays that require switching of three computer RGB or high-definition YPbPR analog video signals. The FSAV433’s high bandwidth and low differential gain and phase provide minimal signal distortion, high video image integrity and “transparent” switching operation. The ultra-low power FSAV433 is complemented by excellent Off Isolation and crosstalk characteristics eliminating active channel-to-channel noise and annoying ghosting effects in the display. Moreover, the switch’s low On Resistance (RON) results in minimal signal insertion loss, further increasing signal quality.
