HDMI Repeater > Switcher

Part Number:EP9431

 

Overview

EP9431 is a 4 inputs HDMI 1.3b switch with integrated Equalizer and DDC/HPLG switches. The chip provides 4 HDMI receiver inputs and one HDMI transmitter output. The chip uses Re-Sample and Re-Drive architecture which re-samples data at the receiver side and re-drive data at the transmitter side. This architecture will not pass through noise from inputs to output and hence provides reliable transmission. The chip supports TMDS clock from 25 Mhz to 225 Mhz (12-bit color 1080p).
