PI3HDMI412-AZHE

COMPANY CONFIDENTIAL PI3HDMI412-A 4-Differential Channel, 2:1 Mux/DeMux, DVI/HDMI Compliant Signal Switch based on TMDS Signaling Standard Features 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 PI3HDMI412-A is a 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 TMDS Signaling Data Rate: 1.65Gbps Crosstalk: -25dB@825MHz Switching speed: 4ns Isolation: -30dB@825MHz 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): - 42-pin TQFN (ZH) - 48-pin BQSOP (B) 
 
 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.

  The maximum DVI/HDMI data rate of 1.65Gbps 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.
