Video Section Components

Part Number	Functional Description
	The MAX3845 is a TMDS® 2-to-4 fanout switch and cable driver for multimonitor distribution
	of DVI or HDMI™ ( high-definition multimedia interface) signaling up to 1.65Gbps. Both inputs
	and outputs are standard TMDS signaling, as per DVI and HDMI standards. Because TMDS
	links are “point-to-point,” buffering is required for fanout applications. Four DVI/HDMI TMDS
	outputs are provided for fanout distribution. Each TMDS output can be independently
	sourced from either input or can be turned off. Each TMDS input or output is composed of
	four differential channels that can be arbitrarily assigned to the three data signals and the
MAX3845	1/10th-rate clock. The data rate depends on resolution, but it can vary from 250Mbps (VGA)
	to 1.65Gbps (UXGA or 1080p/60).
	Typical applications include multiroom display of the same video source, and industrial and
	commercial signage applications such as airport monitors or trading-room floor displays. The
	MAX3845 includes selectable output preemphasis that extends output cable reach up to an
	additional 7m.

	The MAX3814 TMDS EQ/driver compensates for FR-4 and cable losses to the DVI/HDMI
	transmit connector, and provides a fully compliant DVI/HDMI TMDS output. The device can
MAX3814	also be used in DVI/HDMI cable applications to extend reach and improve jitter margin of
	cable channels at the receive-side connector.

	The MAX4814E bidirectional 2:4 HDMI switch provides routing for low-frequency signals. The
	MAX4814E operates from a single +5.0V ±10% supply voltage and is ideal for connecting
MAX4814E	multiple HDMI sources to multiple loads.

MAX3208	The MAX3208E is a low-capacitance, ±15kV ESD-protection diode array with an integrated
	transient voltage suppressor (TVS) clamp. The device is suitable for high-speed and general-
	signal ESD protection. Low input capacitance makes this device ideal for ESD protection of
	signals in HDTV; PC monitors (DVI, HDMI); PC peripherals (FireWire®, USB 2.0); server
	interconnect (PCI Express®, Infiniband®); datacom;and interchassis interconnect.
