BA7627FV

TECHNICAL NOTE High performance video signal Switcher Triple Circuits Video Signal Switchers BA7602F, 03F, 06F/FS, 07F, 09F, 27FV ●Description These video switching ICs, which contain two or three 2-input circuits, were developed for switching TV, DVD, and other video signals. Input pin formats can be selected from bias mode (R=20 kΩ), sync-tip mode, and pedestal clamp mode. Having a large dynamic range and broad frequency characteristics, these switches are suited to a wide range of applications from audio signals to video signals. ●Features 1) Contain three 2-input, 1-output switch circuits (BA7602F,03F,06F/06FS,07F,09F,27FV) 2) Power supply voltage (4.5~5.5 V) 3) Low power consumption 4) Good frequency characteristics 5) Large dynamic range 6) Bias input (BA7602F) Sync-tip clamp input (BA7603F) Pedestal clamp input (BA7606F/06FS) Bias input + sync-tip clamp input (BA7607F,09F, 27FV) 7) Large input impedance (Typ.20kΩ) 8) Fast switching speed (Typ. 50ns) ●Use For switching TV, DVD, and Other video signals ●Lineup Circuit current （mA） 14.0 13.0 15.0 12.5 12.5 12.5 Distortion （％） － － － 0.007 0.007 0.007 Maximum output level （VP-P） 3.1 2.9 2.6 3.0 3.0 3.0 Part No. BA7602F BA7603F BA7606F/FS BA7607F BA7609F BA7627FV Built-in circuit 2 in 3 circuits 2 in 3 circuits 2 in 3 circuits 2 in 3 circuits 2 in 3 circuits 2 in 3 circuits Input type Bias Clamp Pedestal Clamp Clamp 2 Bias1 Clamp 1 Bias 2 Clamp 2 Bias1 Package SOP16 SOP16 SOP16/ SSOP-A16 SOP16 SOP16 SSOP-B16 Aug. 2008 ●Absolute Maximum Ratings（Ta=25℃） Parameter Symbol Supply voltage Vcc BA7602F BA7603F BA7606F Power BA7607F Pd dissipation BA7609F BA7606FS BA7627FV Operating temperature Topr Storage temperature Tstg Limits 9 500 *1 Unit V mW 650 *2 450 *1 －40～＋85 －55～＋125 ℃ ℃ *1 Deratings is done at 5.0mW/℃ above Ta=25℃.（BA7604N, 05N ,02F, 03F, 06F, 07F, 09F, 27FV） *2 Deratings is done at 6.5mW/℃ above Ta=25℃.（BA7606FS） ●Operating Range（Ta=25℃） Parameter Symbol Supply voltage Vcc Min. 4.5 Typ. 5.0 Max. 5.5 Unit V ●Electrical characteristics (Unless otherwise noted, Ta=25℃ and Vcc=5.0V) Typical value Parameter Symbol 02F 03F 06F/FS 07F Circuit current Icc Vom1 Vom2 VomU VomD Gv CT Gf THD VTH Vct 14.0 ― 3.1 ― 13.0 2.9 ― 15.0 ― ― 09F 12.5 27FV Unit mA VP-P VP-P VP-P VP-P Conditions ― f=1kHz, THD=0.5%, with clamp f=1kHz, THD=0.5%, without clamp Dynamic range on positive side of clamp level Dynamic range on negative side of clamp level ｆ=1MHz, VIN＝1 VP-P ｆ=4.43MHz, VIN=1 VP-P 10MHz/1MHz, VIN= VP-P ｆ=1kHz, 1Vp-p, Bias type H: IN1 L: IN2 Only BA7606F/FS Maximum output level1 Maximum output level2 Maximum output level U Maximum output level D Clamp Bias Pedestal clamp Pedestal clamp 2.9 3.0 ― 1.65 0.95 0 -65 ― ― Voltage gain Interchannel crosstalk Frequency characteristic Total harmonic distortion CTL pin switching level Clamp input level 0 ― -1 0 0.007 2.5 dB dB dB % V V L≦0.75 H≧2.2 ●Cautions on use 1) Numbers and data in entries are representative design values and are not guaranteed values of the items. 2) Although we are confident in recommending the sample application circuits, carefully check their characteristics further when using them. When modifying externally attached component constants before use, determine them so that they have sufficient margins by taking into account variations in externally attached components and the Rohm LSI, not only for static characteristics but also including transient characteristics. 3) Absolute maximum ratings If applied voltage, operating temperature range, or other absolute maximum ratings are exceeded, the LSI may be damaged. Do not apply voltages or temperatures that exceed the absolute maximum ratings. If you think of a case in which absolute maximum ratings are exceeded, enforce fuses or other physical safety measures and investigate how not to apply the conditions under which absolute maximum ratings are exceeded to the LSI. 4) GND potential Make the GND pin voltage such that it is the lowest voltage even when operating below it. Actually confirm that the voltage of each pin does not become a lower voltage than the GND pin, including transient phenomena. 5) Thermal design Perform thermal design in which there are adequate margins by taking into account the allowable power dissipation in actual states of use. 6) Shorts between pins and misinstallation When mounting the LSI on a board, pay adequate attention to orientation and placement discrepancies of the LSI. If it is misinstalled and the power is turned on, the LSI may be damaged. It also may be damaged if it is shorted by a foreign substance coming between pins of the LSI or between a pin and a power supply or a pin and a GND. 7) Operation in strong magnetic fields Adequately evaluate use in a strong magnetic field, since there is a possibility of malfunction. 8) A bias input coupling capacitor on the order of 10 μF~33 μF is appropriate. 9) A clamp input coupling capacitor on the order of 0.1 μF~1 μF is appropriate. 10) Make the clamp pulse width of the BA7606F/FS at least 1 μs. 2/8 ●Block diagram Fig.1 BA7602F Fig.2 BA7603F Fig.3 BA7606F/FS Fig.4 BA7607F, BA7627FV CTL pin settings CTL Ｌ Ｈ OUTPUT IN2 IN1 Fig.5 BA7609F 3/8 ●Reference data Pin DC voltage（VCC=5V, Ta=25℃） Pin DC voltage (V) Pin No. BA7602F 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 3.27 4.91 1.84 0 1.84 1.84 4.91 3.27 3.27 0 3.27 4.91 5.00 3.27 0 3.27 BA7603F 2.05 4.91 0.65 0 0.65 0.65 4.91 2.05 2.05 0 2.05 4.91 5.00 2.05 0 2.05 BA7606F/FS 2.96 4.91 1.54 0 1.54 1.54 4.91 2.96 2.96 4.97 2.96 4.91 5.00 2.96 0 2.96 BA7607F BA7627FV 2.05 4.91 0.65 0 0.65 1.76 4.91 2.48 2.48 0 2.05 4.91 5.00 2.05 0 2.05 BA7609F 2.48 4.91 1.76 0 1.76 0.65 4.91 2.05 2.05 0 2.48 4.91 5.00 2.48 0 2.48 Input/Output impedance Limits (Typical) 02F Bias Clamp 20k ― 30 30※ 03F ― 06F/FS ― 1.7M 30 07F/27FV 20k 09F Unit Ω Ω Ω Parameter Input impedance Input impedance Output impedance ※The 6pin output impedance in the BA7606F/FS is 130Ω. 4/8 ●Measurement circuit 1/2 (BA7602F,BA7603F,BA7607F, BA7609F) Fig.6 BA7602F, BA7603F, BA7607F, BA7609F, BA7627FV 5/8 ●Measurement circuit 2/2 (BA7606F/FS) Input waveform Output waveform Fig.7 BA7606F/FS 6/8 ●Reference data 30 CIRCUIT CURRENT : Icc (mA) 25 20 15 BA7603F Vcc=5.0V 0 -0.5 BA7603F Ta=25℃ Vcc=6.0V Vcc=5.0V 0 -0.5 -1 GAIN (dB) -1.5 -2 -2.5 -3 -3.5 -4 BA7603F Vcc=5.0V Ta=-30℃ Ta=25℃ Ta=-30℃ GAIN : Gf (dB) -1 -1.5 -2 -2.5 -3 Ta=25℃ Ta=90℃ 10 5 0 4 5 6 7 SUPPLY VOLTAGE : Vcc (V) Vcc=4.0V Ta=90℃ -3.5 -4 0.1 1 FREQUENCY : f (MHz) 10 100 0.1 1 FREQUENCY : f (MHz) 10 100 Fig.8 Circuit current vs. Supply voltage BA7606F Vcc=5.0V, Ta=25℃ Fig.9 Frequency characteristics vs. Supply voltage BA7606F INPUT IN2a(1pin) f=1MHz,1Vpp Vcc=5.0V, Ta=25℃ Fig.10 Frequency characteristics vs. temperature BA7606F INPUT IN2a(1pin) f=1MHz,1Vpp Vcc=5.0V, Ta=25℃ 0 -10 -20 GAIN (dB) -30 -40 -50 -60 -70 -80 0.1 OUTa (3pin) 500mV/DIV OUTa (3pin) 500mV/DIV CTLa (2pin) 2V/DIV 20nsec/DIV 0.2 0.3 0.5 CTLa (2pin) 2V/DIV 20nsec/DIV 1 2 3 5 10 FREQUENCY (MHz) Fig.12 Switching characteristics1 OFF→ON Fig.13 Switching characteristics2 ON→OFF Fig.11 Interchannel crosstalk ●Selection of order type B A 7 6 0 2 F E 2 Part.
