FSHDMI04 Wide-bandwidth Differential Signaling HDMI Switch
October 2005 Revised October 2005
FSHDMI04 Wide-bandwidth Differential Signaling HDMI Switch (Preliminary)
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 resolution. It can also be used to switch other LVDS or TMDS based DVI digital video signals as well as 1000-BaseT Gigabit Ethernet. Possible applications include LCD TV, DVD, Set-Top Box, and notebook computer and other designs with multiple digital video interfaces. The FSHDMI04 switch allows the passage of HDMI link signals with low non-adjacent channel crosstalk and superior 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.
Features O 1.65 Gbps Throughput O -25dB non-adjacent channel crosstalk at 825MHz O Isolation ground between channels O Fast turn on/off time O Low power consumption (1PA max) O Control input: TTL compatible O Available in 48-lead QVSOP package Applications O UXGA and 1080p DVI and HDMI video source selection

Note 1: 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 rating. The Recommended Operating Conditions tables will defined the conditions for actual device operation. Note 2: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. Note 3: Unused control inputs must be held HIGH or LOW. They may not float
