Pericom Semiconductor’s PI3HDMI series of switch circuits
are targeted for high-resolution video networks that are based
on DVI/HDMI standards, and TMDS signal processing. The
PI3HDMI412FT-A is an 8- to 4-Channel Mux/DeMux Switch. The
device multiplexes differential signals to one of two corresponding
outputs. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. It is designed for low
bit-to-bit skew and high channel-to-channel noise isolation.
4-Differential Channel 2:1 Mux/DeMux
HDMI 1.1, 1.2, and 1.3 compatible
Allowable Data Rate: > 5.0 Gbps
Supports both AC coupled and DC coupled signals
Switching speed: 4ns
Isolation: -40dB @ 2.0 Gbps
Crosstalk: -31dB @ 2.0 Gbps
ESD: Data bits @ 8kV contact, select bit @ 2kV HBM
Low bit-to-bit skew
Enable/Disable Time: 9ns
Bidirectional
Packaging (Pb-free & Green):
— 42-pin TQFN (ZH42)
— 48-pin BQSOP (B48)
The allowable data rate of 5.0Gbps provides the resolution required
by the 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.
Due to its integrated pull-up resistors, the product has been designed
specifically for applications where the part is used as a 2 to 1 mux,
not 1 to 2 demux. Therefore, Pericom only recommends the part
to be used as a 2 to 1 mux when dealing with HDMI signals. Even
though the passive circuitry does not eliminate the bi-directional
functionality, it is not ideal when used with HDMI signals. If DVI
are used, either direction can be used.

Notes:
1. CL = Load capacitance: includes jig and probe capacitance.
2. RT = Termination resistance: should be equal to ZOUT of the Pulse Generator
3. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
4. All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, ZO = 50Ω, tR ≤ 2.5ns, tF ≤ 2.5ns.
5. The outputs are measured one at a time with one transition per measurement.
