Notes:
1. All typical values are at 25
°C and with a 3.3V supply.
2.
tsk(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 VDD pins are recommended to have a 0.01μF capacitor tied from VDD to GND to filter supply noise
TMDS inputs
Standard TMDS terminations have already been integrated into Pericom’s PI3HDMI301 device. Therefore, external terminations
are not required. Any unused port must be left floating and not tied to GND.
