3:1 Active HDMI^TMCompatible Switch with Optimized

Equalization for Enhanced Signal Integrity

Description

Features

Pericom Semiconductor’s PI3HDMI431AR 3:1 active switch

circuit is targeted for high-resolution video networks that are

• Supply voltage, V = 3.3V ±5%

• Each Port is compatible w/ DVI, HDMI^TM1.1, HDMI^TM1.2 or

based on DVI/HDMI^TMstandards and TMDS signal processing.

The PI3HDMI431AR 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 three controllable output swings that can be

controlled through a single bit. The allowable output swings are

500mV, 750mV and 1000mV. This solution also provides a unique

advanced pre-emphasis technique to increase rise and fall times

which are reduced during transmission across long distances.

HDMI^TM1.3 signals

• Supports both AC-coupled and DC-coupled inputs

• Deep Color^TMSupport

• High Performance, up to 2.5 Gbps per channel

• Switching support for 3 side band signals

(SCL, SDA and HPD)

• 5V Tolerance on all side band signals

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

HOT INSERTION

Each complete HDMI^TM/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).

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

speed signal input

• Conﬁgurable output swing control

(500mV, 750mV, 1000mV)

• Conﬁgurable Pre-Emphasis levels

(0dB, 1.5dB, 3.5dB, & 6.0dB)

• Conﬁgurable De-Emphasis

(0dB, -3.5dB, -6.0dB, -9.5dB)

The maximum DVI/HDMI^TMBandwidth of 2.5 Gbps provides 12-

bit deep color support, which is offered by HDMI^TMrevision 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 PI3HDMI431AR is the industry’s ﬁrst active

DVI/HDMI^TMswitch compatible with HDMI^TM1.1, 1.2, and 1.3

which ensures transmitting high-bandwidth video streams from

video components to the display unit. The PI3HDMI431AR also

provides enhanced robust ESD/EOS protection of 12kV, which is

required by many consumer video networks today.

• Optimized Equalization

Single default setting will support all cable lengths

• 12kV HBM ESD protection on all high speed data channels

• Propagation delay ≤ 2ns

• High Impedance Outputs when disabled

• Packaging (Pb-free & Green): 64-contact TQFN (ZL64)

The Optimized Equalization provides the user a single optimal

setting that can provide HDMI^TMcompliance for all cable lengths:

1meter to 20meters and color depths of 8bit/ch, or 12bit/ch.

Pericom also offers the abiility 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.
