1/19 www.rohm.com 2009.05 - rev.d ? 2009 rohm co., ltd. all rights reserved. hdmi switch ics 3 for input 1 output switch with termination sense correspondence (sync with hpd_sink) bu16018kv description bu16018kv is 3 for input 1 output hdmi/dvi switch lsi. each port supports 2.25gbps. (hdmi 1.3a). this device control is simple. it requires only 3.3v source and a few gpio controls. terminated resistors(50 ? ) are integrated at each input port. when channel is not selected, termination resistors are turned off. tmds inputs are high impedance. this device is integrated equaliz ation function and ddc buffer function, so it can adapt long cable. features 1) supports 2.25 gbps signaling rate for 480i/p , 720i/p, and 1080i/p resolution to 12-bit color depth 2) compatible with hdmi 1.3a 3) each port supports hdmi or dvi inputs 4) 5v tolerance to all ddc and hpd_sink inputs 5) integrated ddc buffer 6) integrated switchable 50 receiver termination 7) integrated equalizer circuit to adapt long cable 8) high impedance outputs when disabled 9) hbm esd protection exceeds 10kv 10) 3.3v supply operation 11) vqfp80 package 12) rohs compatible applications digital tv, dvd player, set-top-box, audio video re ceiver, digital projector, dvi or hdmi switch box line up matrix part no. power supply (v) esd (kv) input (ch) output (ch) data rate (gbps) hot plug control termination sense correspondence switching method ddc buffer equalizer de emphasis package rohs bu16020kv 3 to 3.6 10 hdmi 4ch hdmi 1ch 2.7 yes yes gpio/i 2 c yes yes (adaptive) yes vqfp100 yes bu16018kv 3 to 3.6 10 hdmi 3ch h d mi 1c h 2. 25 yes yes g pi o yes yes yes vq f p8 0 yes bu16027kv 3 to 3.6 10 hdmi 3ch h d mi 1c h 2. 25 yes yes g pi o yes yes yes (always on) vqfp64 yes BU16006KV 3 to 3.6 10 hdmi 2ch h d mi 1c h 2. 25 yes yes g pi o yes yes yes (always on) vqfp64 yes bu16024kv 3 to 3.6 10 hdmi 1ch h d mi 1c h 2. 25 yes yes - yes yes yes vq f p4 8c yes no.09063edt02
