Product Description

PI3HDMI511 is TMDS Redriver supporting HDMI 1.4 and DVI specifications up to a data rate of 3.4Gbps with 48-bit per pixel Deep ColorTM. It also support enhanced robust ESD/EOS protection of 8kV, which is required by many consumer video networks today.

It converts the DC and AC coupled source devices into the HDMI compliant signal with proper signal swing, espically in the Notebook HDMI and Dual mode DP PC systems.

Programmable termination settings at TMDS input help to avoid the compatibility issue caused by non standard HDMI source to determine the connection status of TMDS channel with proper termination voltage setting.

With Diodes' intelligent power management techniques, the PI3HDMI511 can automatically enter low power states when no valid signal presents on the TMDS link.
