FSHDMI08 — Low-Voltage, Wide-Bandwidth, HDMI Switch with DDC and CEC Multiplexer Features Description The FSHDMI08 is a wide-bandwidth switch designed for routing HDMI link data, clock, and the relevant DDC and CEC control signals that support the data rate up to 1.65Gbps per channel for UXGA resolution. Applications include LCD TVs, DVD, set-top boxes, and notebook designs with multiple digital video interfaces. -25db Non-Adjacent Channel Crosstalk at 1.65Gbps Low Signal Loss: -1.5dBg attenuation at 1.65Gbps Isolation Ground Between Channels Fast Turn-on/off Time (< 6ns) 1.65Gbps Throughput This switch allows the passage of HDMI link signals with ultra-low non-adjacent channel crosstalk and ultralow off isolation. This 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 with minimal additive skew and phase jitter. The pinout supports an HDMI standard-A connector PCB layout. 8kV ESD Protection Low Skew: Intra-pair <90ps, Inter-pair < 150ps Low Power Consumption: 1µA Maximum Applications XGA and 720p DVI and HDMI Video Source Selection IMPORTANT NOTE: For additional information, analogswitch@fairchildsemi.com.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
