Wide-Bandwidth 2 x 1 VIDEO MULTIPLEXER
FEATURES
q BANDWIDTH: 210MHz (1.4Vp-p) q LOW INTERCHANNEL CROSSTALK: –79dB (30MHz, SO); –77dB (30MHz, DIP) q LOW SWITCHING TRANSIENTS: +13mV/–4mV q LOW DIFFERENTIAL GAIN/PHASE ERRORS: 0.03%, 0.01° q LOW QUIESCENT CURRENT: One Channel Selected: ±4.6mA No Channel Selected: ±120µA The MPC104 consists of two identical monolithic, integrated, open-loop buffer amplifiers, which are connected internally at the output. The bipolar complementary buffers form a unidirectional transmission path and offer extremely high output-to-input isolation. The MPC104 multiplexer enables the user to connect one of two input signals to the output. The output of the multiplexer 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 5nV/√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 spacesaving 8-pin SO and DIP packages. Both are designed and specified for operation over the industrial temperature range (–40°C to +85°C.)

q VIDEO ROUTING AND MULTIPLEXING (CROSSPOINTS) q RADAR SYSTEMS q DATA ACQUISITION q INFORMATION TERMINALS q SATELLITE OR RADIO LINK IF ROUTING
DESCRIPTION
The MPC104 is a wide-bandwidth, 2-to-1 channel video signal multiplexer, which can be used in a wide variety of applications. It was designed for wide-bandwidth systems, including high-definition television and broadcast equipment. Although it is primarily used to route video signals, the harmonic and dynamic attributes of the MPC104 also make it appropriate for other analog signal routing applications such as radar, communications, computer graphics, and data acquisition systems.
