2:1 ActiveEye™ HDMI™ Switch with Automatic Power Down
and Dual SEL Control for Source Applications
Description
Features
ÎÎ2
Fully compatible HDMI™ signal support with backward compatibility to the DVI 1.0 standard, Pericom’s new “ActiveEye™”
switch technology is all you need to connect multiple, unknown
sources, to a single display. Without any affect on HDCP, these
switches can be used almost anywhere. In addition to supporting
DC coupled HDMI and DVI inputs, Pericom's PI3HDMI221-A
can also level shift an AC coupled HDMI to a DC coupled HDMI
output.
Pericom’s HDMI product family has been designed specifically
to support color depths of up to 12bits per channel, as specified
in the HDMI revision 1.3 standard. We have integrated the entire
interface solution so the TV designer doesn’t have to think about
it. This includes, integrated DDC switching.
digital video inputs can be switched to a single output
ÎÎEach
input can be AC coupled video or DC coupled, while
the output will maintain its DC coupled, current-steering,

ÎÎTMDS

2.5Gbps per lane)
ÎÎDeep

Recommended Power Supply Decoupling Circuit
Figure 1 is the recommended power supply decoupling circuit configuration. It is recommended to put 0.1µF decoupling capacitors
on each VDD pins of our part, there are four 0.1µF decoupling capacitors are put in Figure 1 with an assumption of only four VDD
pins on our part, if there is more or less VDD pins on our Pericom parts, the number of 0.1µF decoupling capacitors should be adjusted according to the actual number of VDD pins. On top of 0.1µF decoupling capacitors on each VDD pins, it is recommended to put a
10µF decoupling capacitor near our part’s VDD, it is for stabilizing the power supply for our part. Ferrite bead is also recommended
for isolating the power supply for our part and other power supplies in other parts of the circuit. But, it is optional and depends on the
power supply conditions of other circuits.

Requirements on the Decoupling Capacitors
There is no special requirement on the material of the capacitors. Ceramic capacitors are generally being used with typically materials of X5R or X7R.
Layout and Decoupling CapacitorPlacement Consideration
i. Each 0.1µF decoupling capacitor should be placed as close as possible to each VDD pin.
ii. VDD and GND planes should be used to provide a low impedance path for power and ground.
iii. Via holes should be placed to connect to VDD and GND planes directly.
iv. Trace should be as wide as possible
v. Trace should be as short as possible.
vi. The placement of decoupling capacitor and the way of routing trace should consider the power flowing criteria.
vii. 10µF capacitor should also be placed closed to our part and should be placed in the middle location of 0.1µF capacitors.
viii.Avoid the large current circuit placed close to our part; especially when it is shared the same VDD and GND planes. Since large
current flowing on our VDD or GND planes will generate a potential variation on the VDD or GND of our part.
