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.
Applications
• UXGA and 1080p DVI and HDMI video source

Absolute Maximum Ratings
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The
device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are
not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table defines the condi-
tions for actual device operation.

Notes:
1. The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are
observed.
2. Unused control inputs must be held HIGH or LOW. They may not float.
3. Measured by the voltage drop between A and B pins at the indicated current through the switch. On resistance is
determined by the lower of the voltages on the two (A or B) pins.
4. Flatness is defined as the difference between the maximum and minimum value on resistance over the specified
range of conditions.
