HDMI Repeater IC

HDMI repeater IC is a chip that can regenerates HDMI signals to improve the quality. With using equalization technologies, our signal repeater can adjust and correct for known channel losses at the transmitter and restore signal integrity at the receiver.


Explore EP92A6SQ is a 3-in-1-out repeater IC that supports HDMI 2.0 and MHL 2.1 with HDCP 1.4 and 2.2. This chip has 1 HDMI/MHL dual mode input port and 2 HDMI input port. For content security, it supports HDCP decryption, audio outputs, audio inputs and HDCP re-encryption in repeater mode. And it can perform HDCP 1.4 to HDCP 2.0 conversion or vice versa.

EP92A6SQ supports even/odd or left/right dual 3G to single 6G conversion. And it also supports 6G to 3G conversion that convert 4K2K 60Hz YCbCr444 to 4K2K 60Hz YCbCr420 to reduce bandwidth. This chipĀ supports audio output in IIS and SPDIF. The audio for the HDMI output can be from a regenerated LPCM audio source or by-passed audio from the selected HDMI input port. It has high supportability for SD/HD audio and HD/3D/4K2K video up to 60Hz frame rate. And it also has ARC receiver and transmitter function.

It can be used in Home Theatre or Sound Bar Speaker, receiving the HDMI signal from source like BluRay player and transmitting the high definition video signal to TV, while audio can be played from speaker.
