BA7653AFV-E2

High-performance Video Signal Switchers Single-circuit Video Switchers BA7654F,BA7653AF,BA7653AFV,BA7652AF No.11066EAT04 ●Description The BA7654F, BA7653A F/FV or BA7652AF is a video signal (display signal) switch containing one 2-input or 3-input circuit. Each of the input pin formats is “sync-tip clamp input” that matches the synchronous tips of video signals (display signals) to the same potential. The inputs have an high input impedance configuration, in which they can utilize a small clamp capacitor (0.01 µF (FZ) ceramic capacitor is recommended). ●Features 1) Low value clamp capacitance can be used (Min. 3000 pF Recommended 0.01µF (FZ) ceramic capacitor) 2) Low voltage operation is possible (Operating range 4.0～7.0V) 3) Superimposed can be applied since switching speed of SW is fast and there is little switching noise (Typ. 70ns) 4) Low power consumption (Typ. 25mW when Vcc=5V) 5) Large dynamic range (Typ. 3.1VP-P when Vcc=5V) 6) Good frequency characteristics (Typ. 10 MHz 0 dB) 7) Low interchannel crosstalk (Typ. –70 dB) 8) Voltage can be applied to the CTL pin without a VCC voltage. 9) Built-in mute function (BA7652AF) ●Applications VCR, TV, and other applications that use display signals. ●Product lineup Part No. Input type Mute BA7654F 2 in 1 Circuit － BA7653AF, BA7653AFV 3 in 1 Circuit － BA7652AF 3 in 1 Circuit ○ Supply voltage(V) 4.0 ～ 7.0 ●Absolute maximum ratings(Ta=25℃) Parameter Symbol Supply voltage Ratings BA7654F BA7653AF VCC BA7653AFV BA7652AF 9 Unit V Pd 500*1 500*1 350*2 500*1 mW Operating temperature Topr -25～+75 -30～+80 -30～+80 -30～+80 ℃ Storage temperature Tstg Power dissipation -55～+125 ℃ *1 Reduce by 5.0mW/℃ over 25℃, when mounted on a 50mm×50mm PCB board.(BA7654F, BA7653AF, BA7652AF) *2 Reduce by 3.5mW/℃ over 25℃, when mounted on a 50mm×50mm PCB board.(BA7653AFV) www.rohm.com © 2011 ROHM Co., Ltd.

Numbers and data in entries are representative design values and are not guaranteed values of the items. 2. Although ROHM is confident that the example application circuit reflects the best possible recommendations, be sure to verify circuit characteristics for your particular application. Modification of constants for other externally connected circuits may cause variations in both static and transient characteristics for external components as well as this Rohm IC. Allow for sufficient margins when determining circuit constants. 3. Absolute maximum ratings Use of the IC in excess of absolute maximum ratings, such as the applied voltage or operating temperature range (Topr), may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode) when such damage is suffered. A physical safety measure, such as a fuse, should be implemented when using the IC at times where the absolute maximum ratings may be exceeded. 4. GND potential Ensure a minimum GND pin potential in all operating conditions. Make sure that no pins are at a voltage below the GND at any time, regardless of whether it is a transient signal or not. 5. Thermal design Perform thermal design, in which there are adequate margins, by taking into account the permissible dissipation (Pd) in actual states of use. 6. Short circuit between terminals and erroneous mounting Pay attention to the assembly direction of the ICs. Wrong mounting direction or shorts between terminals, GND, or other components on the circuits, can damage the IC. 7. Operation in strong electromagnetic field Using the ICs in a strong electromagnetic field can cause operation malfunction. 8. For clamp operation stability Set the output impedance of the stage before input pin no more than 1 kΩ. 9. An input clamp capacitor will cause delay in operation at power on. Therefore, it is recommended to use a clamp capacitor no larger than 0.1 µF (0.01µF (FZ) ceramic capacitor is recommended). 10. TheBA7653AF, BA7653AFV and BA7652AF are 3-input, 1-output switch. If it is used as a 2-input, 1-output switch, by leaving one input Open and unused, the Open input pin will oscillate. However, this does not affect other pins and is not particularly a problem for operation. If necessary, connect the input pin to GND via a capacitor or connect the input pin directly to VCC to stop oscillation. 11. CTL pin is in indeterminate status when left Open. Set it at “H” or “L” level. 12. For superimposed, a 1.7v DC voltage should be applied directly to an input pin. www.rohm.com © 2011 ROHM Co., Ltd.
