HDMI Switch ICs

3 for input 1 output switch with

Termination sense

non correspondence

(Unsync with HPD_SINK)

BU16027KV

●Description

BU16027KV 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

Ω) are integrated at 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) 5V tolerance to all DDC and HPD_SINK inputs

4) Integrated DDC buffer

5) Integrated switchable 50

Ωreceiver termination

6) Integrated equalizer circuit to adapt long cable

7) HBM ESD protection exceeds 10kV

8) 3.3V fixed supply to TMDS I/Os

9) 64Pin VQFP package

10) ROHS compatible

●Applications

Digital TV, DVD Player, Set-Top-Box, Audio Video Receiver, Digital Projector, DVI or HDMI Switch Box
