ROHM BU16024KV

HDMI Switch ICs
No.10063EET01
BU16006KV, BU16018KV, BU16024KV, BU16027KV
●Description
These devices control are simple. It requires only 3.3V source and a few GPIO controls.
Termination resistors (50Ω) 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 50Ω termination 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

●Note for use
1). Attention on use as “repeater” or “source” equipment.
Y and Z terminals are connected to Vcc through ESD diode as Figure 7. When Vcc＋0.4 < AVcc, leak current flows from
AVcc to Vcc. For this current, BU16006KV/BU16027KV can’t pass the compliance test as “Repeater” and “Source”
equipment (Test ID 7-3 VOFF). BU16018KV/BU16024KV is able to pass the compliance test using external element like

2). HPD_SINK Pull down resistance.
HPD_SINK have a 5V tolerant structure shown in Figure 9.It needs some drive current to pull down HPD_SINK "H" to "L".
So to pull down HPD_SINK, please use 10kΩ(or under 10kΩ) resistor.

4). About serial connection notice.
When BU160xxKV output connect to other HDMI sw input like following application the specification of Jitter tolerance is
downed. Especially when system needs 1080p (12bit) data rate and cable or PCB trace lengths between BU160xxKV input
and output is small, Deteriorations of Jitter tolerance is outstanding. This problem also depends on receiver IC
characteristic. When system is required 1080p (12bit), Rohm doesn’t recommend serial connect application.

5). AC Coupling notice
BU160xxKV can also communicate using AC coupling capacitor with TMDS line. But even connecting AC coupling
capacitor, AC current may flow if input common mode voltage between two devices is different. For this current, the lower
common mode voltage devices like PCIe or DP may be damaged by AC current.
Figure 15 AC Coupling connection notice
6). TMDS output offset voltage notice.
Offset voltage may appear to TMDS output when there is no signal to TMDS input differential line. OE should set to “H” to
avoid it.
7). Limitation of Master and slave direction as shown Figure 16.
