Quad, High-speed, High-bandwidth HDMI/DVI Switch Maintains Signal Integrity, Doubles Inputs
Maxim Integrated Products introduced its MAX4886 quad, high-speed, high-bandwidth, HDMI/DVI passive switch capable of switching between two digital video signals into a single monitor or multiple HDMI/DVI connectors while maintaining a high level of signal integrity. To ensure signal integrity at fast switching rates, the device features a wide common-mode signal range that enables rail-to-rail signal switching at data rates in excess of 4 Gbps. As a result, this product performs in general-purpose, differential-switching applications such as full line-rate Gigabit Ethernet, Fibre Channel, and telecom/networking LVDS-based backplanes. Its ability to multiplex two HDMI/DVI video streams into a single port enables the design engineer to address multiple applications in the consumer video and PC marketplace, such as desktop PCs, HDTVs, digital projectors, and other video applications. The MAX4886 contains four differential pairs of 1:2 or 2:1 switches for multiplexing/demultiplexing RGB and CLK video signals in HDMI/DVI switching applications. Based on n-channel MOSFET architecture, these switches include an efficient, internal charge pump, resulting in low quiescent current for power-sensitive designs. Low on-capacitance is 2.5 pF, and on-resistance is 8 ohm, which enables it to meet stringent digital-switching requirements. The MAX4886 operates from a single +3.0V to +3.6V supply and is available in a 3.5 mm × 9.0 mm, 42-pin TQFN package. Pricing starts at $1.50 (1000-up).
