General Description

The FSHDMI04 is a wide bandwidth switch for routing

HDMI Link Data and Clock signals. This device supports

data rates up to 1.65Gbps per channel for UXGA resolu-

tion. It can also be used to switch TMDS-based DVI digi-

tal video streams. Possible applications include LCD TV,

DVD, Set-Top Box, notebook computers and other

designs with multiple digital video interfaces. The

FSHDMI04 switch allows the passage of HDMI link sig-

nals with low non-adjacent channel crosstalk and supe-

rior OFF-Isolation. This performance is critical to

minimize ghost images between active video sources in

video applications. The wide bandwidth of this switch

allows the high speed differential signal to pass through

the switch with minimal additive skew and phase jitter.
