Description

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 out­ puts. 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. The maximum DVI/HDMI data rate of 1.65Gbps provides the reso­ lution 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. Pin Description

This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. Maximum Ratings (Above which useful life may be impaired. For user guidelines, not tested.)

RT = Termination resistance: should be equal to ZOUT of the Pulse Generator 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. All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, ZO = 50Ω, tR ≤ 2.5ns, tF ≤ 2.5ns. The outputs are measured one at a time with one transition per measurement.
