Switches turn to high-resolution displays

The FSAV430 is a high-performance quad SPDT (2:1 multiplexer/demultiplexer) video switch.

The FSAV430 is a high-performance quad SPDT (2:1 multiplexer/demultiplexer) video switch.

Its ultrawide 800MHz (-3dB) bandwidth allows full design flexibility while maintaining absolute signal fidelity.

The FSAV430's low-power (less than 1uA) operation reduces power consumption in LCD monitors and portable systems, and its excellent off isolation (-75dB) eliminates annoying monitor ghosting effects.

The switch's low differential gain and phase maintain stable colour saturation and hue consistency over the full range of brightness levels.

In slim DVD designs for video output connection sharing, the FSAV430 is ideal for emerging high-resolution video applications including HDTV and UXGA monitors.

The FSAV430 device addresses designers' specific challenges in high-resolution video applications.

The combination of wide bandwidth, excellent off isolation and low differential gain offers superb high-resolution performance for portable designs and space-constrained applications requiring small package size and low power consumption.

Fairchild's FSAV430 is designed specifically for switching high-definition YPbPr and computer RGB (up to UXGA) signals in LCD televisions and monitors.

This video switch comes in a choice of ultracompact DQFN packaging as well as traditional TSSOP and QSOP configurations.

For space-constrained designs, DQFN (depopulated quad very thin flatpack no leads) offers a 75% space savings over TSSOP devices, as well as other important design benefits.

For example, noise and crosstalk are reduced to a greater degree between I/O terminals due to the lower capacitance and inductance of the DQFN package, which also runs cooler than leaded package types due to the former's exposed die attach paddle underneath.

These lead-free (Pb-free) products meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020B and are compliant with European Union requirements that will take effect in 2005.

Engineering samples are available now, and production volumes are scheduled for October 2004.
