Description
The PI3V514 is a true bi-directional 5-Port 4:1 multiplexer/
demultiplexer with Hi-Z outputs that is recommended for both RGB
and composite video switching applications. With the additional 2
ports, vertical and horizontal synchronous signals can be switched
in addition to switching the RGB and composite signals between
different components, such as DVD, VCR, PCs and etc. With the
increased 4:1 channels, multiple components, such as VCR, DVD,
PC1, PC2 and etc. can be put on the video networks. The Video
switch can be driven from a current output RAMDAC or voltage
output composite video source.
Low On-Resistance, Low Crosstalk, Low OFF Isolation and wide
bandwidth features make it ideal for video and other applications.
Industry leading advantages include a near-zero propagation delay,
resulting from its low channel resistance and I/O capacitance. The
switch is bidirectional and offers little or no attenuation of the high-
speed signals at the outputs. The device also has exceptional high
current capability which is far greater than most analog switches
offered today. The PI3V514 offers a high-performance (400 MHz),
low-cost solution to switch between video sources.
Applications
Projection TV and LCD TV
Video consumer applications
Analog video signal processing

Notes:
1. N.C. = No internal connection
Notes:
1. For video applications: In order to control Muxing and DeMuxing
of all the 20 to 5 channels with the same control plane, the follow-
ing connectoins need to be made on the board:
a. EN1, EN2 and EN3 need to be tied together
b. S1, S3 and S5 need to be tied together
c. S0, S2, and S4 need to be tied together

Notes:
1. See test circuit and waveforms.
2. This parameter is guaranteed but not tested on Propagation Delays.
3. The switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load
capacitance. The time constant for the switch alone is of the order of 0.30ns for 10pF load. Since this time constant is much
smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational
delay of the switch when used in a system is determined by the driving circuit on the driving side of the switch and its
interaction with the load on the driven side.
