MAX3816ACUE+

MAX3816ACUE+ is an I2C 2-wire extender for DDC in DVI™, HDMI™ and VGA interfaces. The DDC/I2C extender automatically compensates for excess load capacitance of long DVI™, HDMI™ and VGA cables. The MAX3816A features compensation for cable capacitance with a guaranteed range up to 3000pF, typically beyond 5000pF. The MAX3816A detects state change assertion by the logical “AND” of the source side and display side. It asserts the new state with a rail-to-rail slew-rate-limited driver capable of meeting I2C rise- and fall-time requirements under the full load of the cable. After assertion of the new state, a hold off period of 2.5μs prevents a subsequent state change while cable channel settles. Suitable for front-projector DVI/HDMI inputs, high-definition televisions, displays, and computer monitors, DVI/HDMI cable-extender modules and active, cable assemblies.

• Supply voltage range from 3V to 5.5V
• DDC or I2C cable extension up to 60meters at 100Kbps for both clock and data channels
• Single-sided solution requires only one MAX3816A at the display side
• Parallel and serial operating modes
• Prevents ringing due to reflections by terminating transmission line impedance after transitions
• Use with MAX3815 TMDS equalizer to form a complete digital video extension solution
• Optional voltage translation between 5V cable DDC and 3.3V display DDC levels
• 3mA max supply current Icc (VCC=5.5V, VDD =5.5V, 100kbps, 60pF load on cable, 10pF load on display)
• 16 pin TSSOP package
