3:1 Active Switch for HDMI™ Signals with Optimized

Equalization for Enhanced Signal Integrity

Description

Features

Pericom Semiconductor’s PI3HDMI301 3:1 active switch circuit

is targeted for high-resolution video networks that are based

• Supply voltage, V = 3.3V ±5%

• Each of the three input ports can support HDMI™ or DVI

signals

on DVI/HDMI™ standards and TMDS signal processing. The

PI3HDMI301 is an active 3 TMDS to 1 TMDS receiver switch

with Hi-Z outputs. The device receives differential signals from

selected video components and drives the video display unit. It

provides controllable output swings, as well as provides a unique

advanced pre-emphasis technique to increase rise and fall times

which are reduced during transmission across long distances.

• Supports both AC-coupled and DC-coupled inputs

• Supports DeepColor™

• High Performance, up to 2.5 Gbps per channel

• Switching support for 3 side band signals

(SCL, SDA and HPD)

Each complete HDMI/DVI channel also has slower speed, side

band signals, that are required to be switched. Pericom’s solution

provides a complete solution by integrating the side band switch

together with the high speed switch in a single solution. Using

Equalization at the input of each of the high speed channels,

Pericom can successfully eliminate deterministic jitter caused by

long cables from the source to the sink. The elimination of the

deterministic jitter allows the user to use much longer cables (up

to 25 meters).

• 5V Tolerance on all side band signals

• SCL, SDA, and HPD pins are the only pins that can support

HOT INSERTION

• Integrated 50-ohm (±10%) termination resistors at each high

speed signal input

• TMDS input termination control on all high speed inputs

• HDCP reset circuitry for quick communication when

switching from one port to another

• Conﬁgurable output swing control

• Conﬁgurable Pre-Emphasis levels

• Conﬁgurable De-Emphasis

The maximum DVI/HDMIBandwidth of 2.5 Gbps provides 36-bit

Deep Color™ support, which is offered by HDMI™ revision 1.3.

Due to its active uni-directional feature, this switch is designed

for usage only for the video receiver’s side. For consumer video

networks, the device sits at the receiver’s side to switch between

multiple video components, such as PC, DVD, STB, D-VHS,

etc. The PI3HDMI301 also provides enhanced robust ESD/EOS

protection of 8kV, which is required by many consumer video

networks today.

• Optimized Equalization

Single default setting will support all cable lengths

• 8kV Contact ESD protection on all input data/clock channels

per IEC61000-4-2

• Propagation delay ≤ 2ns

• High Impedance Outputs when disabled

• Packaging (Pb-free & Green):

− 80-pin LQFP (FF80)

The Optimized Equalization provides the user a single optimal

setting that can provide passing results for HDMI jitter tests for

all cable lengths: 1meter to 20meters with DeepColor support up

to 36bits.

− 64-pin TQFN (ZL64)

Pericom also offers the ability to ﬁne tune the equalization settings

in situations where cable length is known. For example, if 25meter

cable length is required, Pericom's solution can be adjusted to

16dB EQ to accept 25meter cable length.
