NX5DV330 device highlight

The NX5DV330 is a quad, 1-of-2, high-speed, TTL-compatible video multiplexer/demultiplexer. The low on resistance of the switch allows all inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. It has a digital select input (S), four independent inputs/outputs (nY0, nY1), a common input/output (nZ), and an active LOW enable input (E). All four switches can be quickly turned on and off with the single enable pin. Digital select pin is used to select the I/O channel. Schmitt-trigger action at the enable input and select input makes the circuit tolerant to slower input rise and fall times across the entire V_CC range from 4.0V to 5.5V. The NX5DV330 is characterized for operation from -40°C to +85°C.

Functional Diagram of NX5DV330

• Higher signal bandwidth for more details and high fidelity in images
• Schmitt trigger at control inputs to better tolerate slow edges
• Low R_ON (typically 5Ω) for high-quality color reproduction with higher dynamic range
• Low R_ON for low voltage drop across the switch and reduced signal attenuation
• Low R_ON flatness for reduced total harmonic distortion
• Low leakage current and high isolation for noise free images
• Low crosstalk for low interference between active and idle display terminals
• Bidirectional design results in easy PCB layout for multiplexing/demultiplexing applications
• Low supply current for lower power consumption
• Low differential phase offset for low output skew
• TTL compatible inputs for mixed CMOS/TTL designs
• High isolation between I/O pins to prevent false switching

An analog switch can be modeled as a first order low pass filter. Frequency response of filter is used to estimate the available channel bandwidth. Cutoff frequency is the frequency at which signal is reduced by 3dB. It is typically used as the signal bandwidth of switch. Signals with frequencies above this value are filtered out and the associated data is lost. The figure below shows a cutoff frequency of 420MHz for the NX5DV330.

In the figure below, the on state resistance of NX5DV330 remains low across the entire input voltage range for each V_CC value. With low R_ON, lossless switching of video signals can be achieved for high picture quality.

NX5DV330 switch can be used to select either YUV or YCbCr video formats for a video processor in a video conferencing application, when there are two different video sources e.g. a web cam and a surveillance camera. Video processor can convert the YUV or YCbCr data into digital RGB format for display screen as shown below.
