HDMI Switch ICs

1 for input 1 output buffer

(Sync with OE)

BU16025MUV

No.11063EAT06

●Description

BU16025MUV is HDMI Buffer IC for Source, Sink, and repeater equipment. Each TMDS input has internal 50ohm resistor.

These resistors can be turned off by OE pin control. And BU16025MUV has selectable equalizer circuit and DDC active

buffer to isolate capacitor between input and output.

●Features

1) Support 480i/p, 720p, and 1080i/p 12bit deep color and 2.70Gbps data rate

2) 5V Tolerance to all DDC and HPD_SINK Inputs

3) Integrated active DDC buffer

4) Integrated DDC data line delay mode to get hold margin

5) Integrated Switchable 50ΩReceiver Termination

6) Integrated Low TMDS output swing mode for High speed signal

7) High Impedance Outputs When Disabled

8) TMDS Inputs and output HBM ESD Protection Exceeds 8kV

9) Support AC coupling input (TMDS input common mode voltage is 3.3V)

10) Selectable Receiver Equalization

11) Integrated I²C Identification Data for HDMI/DVI distinction (Display port translator mode)

12) 48-Pin VQFN Package

13) ROHS Compatible

●Applications

Digital TV, DVD player, set-top box, AV receiver, Digital projector, Desktop/Note book PC

(*1) HPD_OFF mode sets Hot plug detect output to High impedance. Except HPD_OFF mode, HPD is always active.

(*2) SDAx/SCLx, SDAy/SCLy have different L level input and output voltage. Please refer recommended operating condition in detail

(*3) HDMIID_EN, I2C_ONB don’t need to be Enable except using internal I²C slave.

(*4) Data hold time increases when DDC_TI= “L”. But Data setup time and holdtime of Start condition decrease.

3)Serial connection of TMDS differential line

The serial connections of TMDS differential line like fig15 decrease the jitter tolerant characteristic. Especially when

system needs 1080p (12bit) data rate, deterioration of Jitter tolerance is outstanding. This problem also depends on

receiver IC characteristic. When 1080p (12bit) is required , Rohm doesn’t recommend cascade connect application.

5)AC Coupling

This IC 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. This AC current may damage the

lower common mode voltage devices like PCIe or DisplayPort.

6)TMDS output offset voltage

Offset voltage may appear to TMDS output when there is no signal to TMDS input differential line. OE should be set to

“H” to avoid it.
