HDMI Switch ICs 3 for input 1 output switch with Termination sense correspondence (Sync with HPD_SINK) BU16018KV No.09063EDT02 ●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(50Ω) 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 equalization 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 50Ωreceiver 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 Receiver, Digital Projector, DVI or HDMI Switch Box ●Line up matrix Part No. Power Supply (V) ESD (KV) BU16020KV 3 to 3.6 10 BU16018KV 3 to 3.6 10 BU16027KV 3 to 3.6 10 BU16006KV 3 to 3.6 10 BU16024KV 3 to 3.6 10 Input (ch) HDMI 4ch HDMI 3ch HDMI 3ch HDMI 2ch HDMI 1ch Output (ch) Data rate (Gbps) Hot Plug Control Termination Sense Correspondence Switching Method DDC Buffer Equalizer De emphasis Package RoHS 2 Yes VQFP100 Yes Yes VQFP80 Yes VQFP64 Yes HDMI 1ch 2.7 Yes Yes GPIO/I C Yes Yes (adaptive) HDMI 1ch 2.25 Yes Yes GPIO Yes Yes HDMI 1ch 2.25 Yes Yes GPIO Yes Yes HDMI 1ch 2.25 Yes Yes GPIO Yes Yes HDMI 1ch 2.25 Yes Yes - Yes Yes www.rohm.com © 2009 ROHM Co., Ltd.
