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.
FSAV433 devices are specifically designed to provide seamless switching and minimal signal routing complexity for
emerging high-definition LCD systems,” says Jerry Johnston, Fairchild product manager for analog switches.
“The FSAV433 simplifies designs, reduces cost and enhances image quality. By replacing two
traditional devices with a single three-port switch, the FSAV433 provides a more cost-effective solution for
processing up to three HD video signals from DVDs, Set-Top Boxes, PCs and other remote devices.”
Key features of the FSAV433 3:1 video switch include:
• High bandwidth: 550 MHz, -3 dB;
• Low differential gain: 0.2%, typical;
Low differential phase: 0.1 degree, typical;
• Ultra-low power consumption: less than 1 µA;
• Excellent Off Isolation: less than 75 dB;
• Superior crosstalk characteristics:
• Low On Resistance: 6.5 Ohms, typical.
Designed with full application
flexibility in mind, the FSAV433 comes in a choice of 20-pin TSSOP (Thin Shrink Small Outline Package) or
ultra-compact 20-terminal DQFN configurations. For space-limited designs, DQFN (Depopulated Quad very thin Flat pack
No leads) is 75% smaller than TSSOP devices, runs cooler and generates lower noise and crosstalk between I/O
terminals due to DQFN’s lower capacitance and inductance.
The lead (Pb)-free FSAV433 meets or
exceeds the requirements of the joint IPC/JEDEC standard J-STD-020B and is compliant with European Union
requirements now in effect.
