eP9452 è un ripetitore HDMI 1.4 4-IN 2-OUT con MHL, ARC e OSD, adatto per applicazioni di Switch Box, TV con PIP/POP e ricevitori AV. Il chip supporta 1 porta di ingresso HDMI/MHL (RX0), 3 porte di ingresso HDMI (RX1, RX2, RX3) e 2 porte di uscita HDMI (TX0, TX1). Il chip supporta 4 cifrari HDCP RX e 2 cifrari HDCP TX. Con 4 cifrari HDCP RX, il chip supporta una commutazione molto rapida delle porte senza la necessità di ripetere l'autenticazione HDCP quando si cambia porta. Questa funzione è denominata Instant Port Switching (IPS). Il chip supporta anche 4 porte di RAM eDID on-chip per risparmiare sui costi del sistema.
Il chip supporta uscite audio in IIS e SPDIF. L'uscita audio e le uscite HDMI possono essere selezionate dalla stessa fonte o da fonti diverse. L'audio per l'uscita HDMI può provenire da una sorgente audio LPCM rigenerata (ingresso dai pin IIS_*_IN) o dall'audio originale della porta di ingresso HDMI selezionata. Il chip supporta l'ARC (Audio Return Channel) RX ed è conforme a HDMI 1.4. Il chip supporta audio SD/HD e video HD/3-D/4K2K fino a un clock TMDS di 340 Mhz.
Il chip supporta anche l'OSD (On-Screen-Display) con 8 finestre OSD, dimensioni dei caratteri configurabili, palette di colori programmabile e varie funzioni di sovrapposizione.

Caratteristica

•On-chip 4-IN 2-OUT HDMI Repeater with equalizer
