Notes:
1. All typical values are at 25

C and with a 3.3V supply.
2.
t
sk(o)
is the magnitude of the difference in propagation delay times between any specified terminals of channel 2 to 4 of a device when inputs
are tied together.
Application Information
Supply Voltage
All V
CC
pins are recommended to have a 0.01uF capacitor tied from V
CC
to GND to filter supply noise
TMDS inputs
Standard TMDS terminations have already been integrated into Pericom’s PI3HDMI341ART device. Therefore, external termina-
tions are not required. Any unused port must be left floating and not tied to GND.
