main receiver chipset
• Low power consumption to support Energy Star
Compliance
• Data rate support up to 3.4Gbps (16bit color depth per
channel)
• 2 pin control for port selection
• 3.3V power and 5V standby power
• ESD protection on all I/O pins
→ ±8kV contact per IEC61000-4-2
→ 7kV HBM per JESD22
• Packaging (Pb-free & Green): 72 - Contact TQFN
Pericom Semiconductor’s PI3HDMI™ series of switch circuits
are targeted for high-resolution video networks that are based on
DVI/HDMI standards. The PI3HDMI1310-A is a 3-to-1 HDMI
Mux/DeMux Switch. It is designed for low bit-to-bit skew and
high channel-to-channel noise isolation. The maximum DVI/
HDMI data rate of 3.4Gbps provides the resolution required
by next generation HDTV and PC graphics. Three differential
channels are used for data (video signals for DVI or audio/video
signals for HDMI), and one differential channel is used for Clock
for decoding the TMDS signals at the outputs.

BLOCK DIAGRAM EXPLANATION
DDC Switch Block
Passive NMOS based 3:1 mux for DDC channels from each HDMI/DVI input connector. This section can remain active even when
3.3V supply is gone, as long as 5.0V from TMDS connector is connected to the PI3HDMI1310-A IC.
3:1 High speed Differential Channel Block
4-differential channels per port. 3 channels are targeted for high speed data channels (250Mbps to 3.4Gbps) and 1 channel is
targeted for high speed clock signal (25MHz to 340MHz).
HPD Control Channels Block
Drives each HPD channels through the input pin, HPD_Sink.
This signal will need to drive external pull-down transistor circuit before connecting to the HDMI/DVI connector. The external
pull down circuit will look like the following:
