DATASHEET WIDE BANDWIDTH VIDEO SIGNAL SWITCH, 5 PORT General Description Features The IDTVS512 is a bi-directional 5-Port 2:1 multiplexer/demultiplexer with Hi-Z outputs for both RGB and composite video switching applications. With the additional two ports, vertical and horizontal synchronous signals can be switched in addition to switching the RGB and composite signals between different components (DVDs, VCRs, PCs, etc.). The VideoSwitch can be driven from a current output RAMDAC or voltage output composite video source. • • • • • • • • • • Low on-resistance, low crosstalk, low OFF isolation and wide bandwidth features make it ideal for video and other applications. The IDTVS512 offers a high-performance (600 MHz), low-cost solution to switch between video sources.

For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Guaranteed by design., 3. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 10pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interactions with the load on the driven side.

For example, given a +3.3V supply, the output enables or select pins may be driven low to 0V and high to 3.6V. Driving IN Rail-to-RailÆ minimizes power consumption. Power-supply Sequencing Proper power-supply sequencing is advised for all CMOS devices. It is recommended to always apply VCC before applying signals to the input/output or control pins. 700 3dB Bandwidth 600 500 400 300 200 100 0 0 10 20 30 40 50 Capacitance Load Bandwidth vs. Capacitance WIDE BANDWIDTH VIDEO SIGNAL SWITCH, 5 PORT 5 CONFIDENTIAL IDTVS512 7013/7 IDTVS512 WIDE BANDWIDTH VIDEO SIGNAL SWITCH, 5 PORT COMMERCIAL TEMPERATURE RANGE Test Circuit For Electrical Characteristics 6V VCC Switch Position 200Ω Pulse Generator Test VOUT VIN D.U.T.
