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
