APPLICATIONS

l VIDEO ROUTING AND MULTIPLEXING (CROSSPOINTS) l RADAR SYSTEMS l DATA ACQUISITION l DISC R/W TEST SYSTEMS l xDSL TEST SYSTEMS The MPC102 consists of four identical monolithic, integrated, open-loop buffer amplifiers. Two buffer outputs are each connected internally at the output. The bipolar complementary buffers form a unidirec- tional transmission path and offer extremely high output-to-input isolation. The MPC102 multiplexer enables the user to connect one of two input signals to the corresponding output. The output of the multi- plexer is in a high-impedance state when no channel is selected. When one channel is selected with a digital “1” at the corresponding SEL input, the component acts as a buffer with high input impedance and low output impedance. The wide bandwidth of over 210MHz at 1.4Vp-p signal level, high linearity and low distortion, and low input voltage noise of 4nV/√Hz make this crosspoint switch suitable for RF and video applications. All performance is specified with ±5V supply voltage, which reduces power consumption in comparison with ±15V designs. The multiplexer is available in a space- saving SO-14 and DIP packages. Both are designed and specified for operation over the industrial tem- perature range (–40°C to +85°C.) SEL 1 SEL 2 SEL 3 SEL 4 VOUT1 VOUT2 0 0 0 0 HI-Z HI-Z

DESCRIPTION

The MPC102 is dual, wide-bandwidth, differential 2- to-1 multiplexer, which can be used in a wide variety of applications. It was designed for wide-bandwidth systems, includ- ing high-definition television and broadcast equip- ment. Although it is primarily used to route video signals, the harmonic and dynamic attributes of the MPC102 also make it appropriate for other analog signal routing applications such as radar, communica- tions, computer graphics, and data acquisition sys- tems.

PACKAGE/ORDERING INFORMATION ELECTROSTATIC DISCHARGE SENSITIVITY This integrated circuit can be damaged by ESD. Burr-Brown 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 degrada- tion 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.

shorter than the typical SEL-to-channel-OFF time of 250ns. following tips are offered as suggestions, not as absolutes. high-speed components when they are used incorrectly.

• Bypass power supplies very close to the device pins. Use tantalum chip capacitors (approximately 2.2µF), a parallel 470pF ceramic chip capacitor may be added if desired. Surface-mount types are recommended due to their low lead inductance.
• PC board traces for signal and power lines should be wide to reduce impedance.
• Make short and low inductance traces. The entire circuit layout should be as small as possible.
• Use a low-impedance ground plane on the component side to ensure that low-impedance ground is available through- out the layout. Grounded traces between the input traces are essential to achieve high interchannel crosstalk rejec- tion.
• Do not extend the ground plane under high-impedance nodes sensitive to stray capacitances, such as the buffer’s input terminals.
• Sockets are not recommended, because they add signifi- cant inductance and parasitic capacitance. If sockets are required, use zero-profile solderless sockets.
• Use low-inductance and surface-mounted components for best ac-performance.
• A resistor (100Ω to 200Ω ) in series with the input of the buffers may help to reduce peaking. Place the resistor as close as possible to the pin.
• Plug-in prototype boards and wire-wrap boards will not function well. A clean layout using RF techniques is essential.
