SGM330A Quad, Wide-Bandwidth SPDT Video Analog Switch

Transcription

1 GERAL DESCRIPTION The SGM330A is a quad, bidirectional, single-pole/doublethrow (SPDT) CMOS video analog switch (Mux/DeMux) designed to operate at a single +5V supply. This 2-channel multiplexer/demultiplexer is recommended for both RGB and composite video switching applications. The video switch can be driven from a current output RAMDAC or voltage output composite video source. Wide bandwidth (500MHz), low on-resistance (6Ω), and low crosstalk make it suitable for high-frequency and other applications. Also this device has exceptionally high current capability which is far greater than most analog switches offered today. The SGM330A offers a high-performance, low-cost solution to switch between video sources. It is specified -40 to +85 temperature range. The SGM330A has lead (Pb) free SO-16, TSSOP-16 and QSOP-16 packages. FEATURES Wide Bandwidth: 500MHz Low On-Resistance: 6Ω (TYP) Low Crosstalk: -60dB at 10MHz (TYP) Single Power Operation: +5V Fast Switching Time Rail-to-Rail Operation Typical Power Consumption (0.1µW) TTL/CMOS Compatible Micro Size Packages SO-16 TSSOP-16 QSOP-16 P CONFIGURATIONS (TOP VIEW) SGM330A APPLICATIONS 1 16 V+ Personal Video Recorders Terrestrial Set-Top Boxes Hard Disk Recorders DVD Players Game Consoles Digital VCRs Desktop Video Editors Audio and Video Switching S 1 A S 2 A D A S 1 B S 2 B D B GND S 1 D S 2 D D D S 1 C S 2 C D C QSOP-16/SO-16/TSSOP-16 REV.

SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
