Rohm BU16018KV 2 for input 1 output switch with termination sense correspondence (sync with hpd sink) Datasheet

HDMI Switch ICs
2 for input 1 output switch with
Termination sense
correspondence
(Sync with HPD_SINK)
BU16006KV
No.09063EDT01
●Description
BU16006KV is 2 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 and a few GPIO controls.
Terminated resistors(50Ω) are integrated at each input port. When channel is not selected, termination resistors are
disconnected. 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) 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

2. tsk(o) is the magnitude of the difference in propagation delay times between any specified terminals of channel of a
devices when inputs are tied together.
3. tsk(pp) is the magnitude of the difference in propagation delay times between any specified terminals of channel of two
devices, or between channel 1 of two devices, when both devices operate with the same source, the same supply voltages,
at the same temperature, and have identical packages and test circuits.

1). HPD_SINK Pull down resistance.
HPD_SINK is a 5V tolerant structure shown in Figure 6-1.
It needs some drive current to pull down HPD_SINK "H" to "L"(max10uA@HPD_SINK=2V).
So to pull down HPD_SINK, please use 10kΩ(or under 10kΩ) resistor.
