com MAX14886 The MAX14886 high-speed, low-skew, active redriver multiplexer is ideal for switching between outputs of dual-graphics systems and signal conditioning to meet HDMIK v.
1.
4 compliance up to 2.
25Gbps at an external HDMI connector.
It is used for switching between integrated (e.
g.
, Intel or AMD) and discrete graphics (e.
g.
, NVIDIA or ATI GPU).
The device is VESA DisplayPortK Interoperability Guideline v.
1.
1a-compliant (requires external DDC logic) and integrates seamlessly with an external HDMI connector on the motherboard.
The device accommodates differential inputs as low as 200mV and drives transition minimized differential signaling (TMDS®) outputs to 1000mV (typ).
A precision resistor on the output level adjust pin (ADJ) allows differentiated output back-termination resistors of 400I (typ) to better meet HDMI mask jitter compliance, while maintaining full TMDS swing requirements.
The device supports AC-(DisplayPort) or DC-(HDMI) coupling directly to the graphics IC and must be DC-coupled to the HDMI connector.
In addition, the device features current backflow protection at the HDMI connector and a low-power, active-high or active-low shutdown mode.
The device operates with a single +3.
3V supply, is specified over the 0NC to +70NC commercial temperature range, and is available in a 5mm x 5mm, 40-pin TQFN package.
