BU16027KV

HDMI Switch ICs 1 for input 1 output buffer with Termination sense correspondence (Sync with HPD_SINK) BU16024KV No.09063EDT03 ●Description BU16024KV is 1 for input 1output HDMI/DVI buffer LSI. Each port supports 2.25Gbps. (HDMI 1.3a). This device control is simple. It requires only 3.3V and a few GPIO controls. Terminated resistors(50Ω) are integrated at each input port. When HPD_SINK is L, 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) 5V tolerance to all DDC and HPD_SINK inputs 4) Integrated DDC buffer 5) Integrated switchable 50Ωreceiver termination 6) Integrated equalizer circuit to adapt long cable 7) Selectable output De-Emphasis Supports 8) High Impedance outputs when disabled 9) HBM ESD protection exceed 10kV 10) 3.3-V supply operation 11) 48-Pin VQFP package 12) ROHS compatible ●Applications Digital TV, DVD Player, Set-Top-Box, Audio Video Receiver, Digital Projector, DVI or HDMI Switch Box, PC ●Line up matrix Part No. BU16020KV BU16018KV BU16027KV BU16006KV BU16024KV Power Supply (V) 3 to 3.6 3 to 3.6 3 to 3.6 3 to 3.6 3 to 3.6 ESD (KV) 10 10 10 10 10 Input (ch) HDMI 4ch HDMI 3ch HDMI 3ch HDMI 2ch HDMI 1ch Output (ch) HDMI 1ch HDMI 1ch HDMI 1ch HDMI 1ch HDMI 1ch Data rate (Gbps) 2.7 2.25 2.25 2.25 2.25 Hot Plug Control Yes Yes Yes Yes Yes Termination Sense Correspondence Yes Yes Yes Yes Yes Switching Method GPIO/I C GPIO GPIO GPIO 2 DDC Buffer Yes Yes Yes Yes Yes Equalizer Yes (adaptive) Yes Yes Yes Yes De emphasis Yes Yes Yes (Always ON) Yes (Always ON) Yes Package VQFP100 VQFP80 VQFP64 VQFP64 VQFP48C RoHS Yes Yes Yes Yes Yes www.rohm.com © 2009 ROHM Co., Ltd.
