Description
The STHDMI002A is a differential Single Pole Double Throw (SPDT) 2 to 1, low Ron, bi-directional HDMI switch designed for advanced TV applications supporting HDMI/DVI which demand high definition superior image quality. The differential signal from the 2 ports of HDMI is multiplexed through the switch to form a single output HDMI channel going to the HDMI receiver while the unselected output goes to the high-Z state.
It is designed for very low cross-talk, low bit-to-bit skew, high channel-to-channel noise isolation and low I/O capacitance. The switch offers very little or practically no attenuation of the high-speed signals at the outputs, thus preserving the signal integrity to pass stringent requirements.
The STHDMI002A also includes the DDC as well as the HPD line switching. The pin layout is optimized for easy PCB routing to the HDMI connector and HDMI receivers.
The maximum DVI/HDMI data rate of 1.65Gbps provides the resolution required by the advanced HDTV and PC...
