HDMI Switch ICs
BU16006KV, BU16018KV, BU16024KV, BU16027KV
No.10063EET01
Description
These devices control are simple. It requires only 3.3V source and a few GPIO controls.
Termination resistors (50) are integrated at all TMDS input port. When channel is not selected, TMDS input termination
resistors are turned off and TMDS inputs are high impedance. These devices are also integrated equalizer circuit to adapt
long cable and DDC active buffer function to isolate capacitance.
Features
1) Supports 2.25 Gbps signaling rate for 480i/p, 720p, 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 active DDC buffer
5) Integrated switchable 50termination resistors
6) Integrated equalizer circuit to adapt long cable
7) HBM ESD protection exceeds 10kV
8) 3.3V fixed supply
9) RoHS compatible
Applications
Digital TV, Audio Video Receiver, Digital Projector, DVI or HDMI Switch Box
