PI3HDMI341AR
3:1 Active HDMI 1.3 Compatible Switch with Optimized
Equalization for Enhanced Signal Integrity
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 PI3HDMI341AR device. Therefore, external termina-
tions are not required. Any unused port must be left floating and not tied to GND.
HPD Pins
The HPD pins on the PI3HDMI341AR require external pull down transistors to maintain a 0V signal when port is not selected, as
follows:
