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 PI3HDMI413
is a 12- to 4-Differential Channel Mux/DeMux Switch. The device
multiplexes differential signals to one of three 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 bitto-bit skew and high channel-to-channel noise isolation.
4-Differential Channel 3:1 Mux/DeMux
TMDS Signaling
Data Rate: 1.65Gbps
Crosstalk: [email protected]
Switching speed: 4ns
Isolation: [email protected]
ESD: Data bits @ 8kV HBM, select bit @ 2 kV HBM
Near-Zero Prop Delay: 250ps max.
Low bit-to-bit skew
Hot insertion capable
Enable/Disable Time: 9ns
Bidirectional
Packaging (Pb-free & Green):
64-pin TSSOP (A)
The maximum DVI/HDMI data rate of 1.65Gbps provides the resolution required by the next generation HDTV and PC graphics.
Because of its passive bidirectional feature, this switch can be
used either at the video drivers side or at the receiver side. For PC
graphics applications, the device sits at the drivers side to switch
between multiple display units such as PC LCD monitor, projector,
TV, etc. For consumer video applications, the device sits at the
receiver end to switch between the source components such as
DVD, D-VHS, STB, etc.

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.
