FSHDMI04 Wide-Bandwidth Differential Signaling HDMI Switch
Features
1.65 Gbps throughput 8kV ESD protection -26dB non-adjacent channel crosstalk at 825MHz Isolation ground between channels Low skew - Inter-pair skew <150ps - Intra-pair skew <90ps * Fast turn on/off time * Low power consumption (1A maximun) * Control input: TTL compatible * * * * *
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 TMDS-based DVI digital 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 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.
Applications
* UXGA and 1080p DVI and HDMI video source selection

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 conditions 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.
